Jefferson National Forest

Jefferson National Forest

Virginia, West Virginia, Kentucky

Managed by U.S. Forest Service, Southern Region

1,670,846 acres (723,531 federal/ 947,315 other)

Website: https://www.fs.usda.gov/gwj

Overview

In western Virginia, Jefferson National Forest contains Mt. Rogers, the state’s highest point at 5,729 feet (see our post on Mt. Rogers National Recreation Area).  There are 17 designated Wildernesses in Jefferson National Forest, second only to the 19 in Alaska’s massive Tongass National Forest.  In 1995, George Washington and Jefferson National Forests were administratively combined.  Is it just us, or does that name seem to celebrate George Jefferson from the 1970s sitcom?  It is supposed to commemorate native-Virginian Thomas Jefferson who was the original author of the 1776 Declaration of Independence and the third President of the U.S.  The Omnibus Public Land Management Act of 2009 created both the Bear Creek (5,503 acres) and Seng Mountain (6,455 acres) National Scenic Areas as specially designated parts of Jefferson National Forest.

Highlights

Blue Ridge Parkway, Mt. Rogers National Recreation Area, Seng Mountain National Scenic Area, Bear Creek National Scenic Area, Settlers Museum of Southwest Virginia, James River Gorge, Mountain Lake, Apple Orchard Falls, Cave Mountain Lake, Glenwood Iron Furnace, High Knob, Little Stony Creek, Lake Keokee, Olinger Gap Trail, Virginia Creeper Trail, Virginia Highlands Trail, Appalachian National Scenic Trail

Must-Do Activity

We have only visited the Mt. Rogers National Recreation Area (which made it on our Top 10 List) portion of Jefferson National Forest, which sits just north of the North Carolina border.  One popular day trip there is to bike the 33-mile-long Virginia Creeper Trail, which is also open to hikers and horse riders.  Last used in 1977, the former railroad grade runs 18 miles downhill from Whitetop Station Visitor Center to the town of Damascus, and local outfitters can provide shuttles to the trailheads and rental bikes.  The trail drops 1,600 feet in total (sometimes at a 7% grade); no wonder those steam locomotives were “creeping” up the hill.  Outside the National Forest, another 15 miles of railroad bed runs to Abingdon and includes the lowest point on the trail at the scenic South Holston Trestle.

Best Trail

Apple Orchard Falls has a drop of 200 feet and can be accessed from Sunset Fields Overlook at Milepost 78 on the Blue Ridge Parkway.  Considered the most popular hike in Jefferson National Forest, the steep trail is only 1.3 miles long one-way, but gains more than 1,000 feet in elevation.  A six-mile loop can be completed by connecting to the Cornelius Creek Trail with a total elevation gain of 1,438 feet.  Olinger Gap Trail is another short, scenic route that connects the 3.7-mile Lake Keokee Loop Trail and the 14-mile Stone Mountain Trail.

Watchable Wildlife

Jefferson National Forest has elevations ranging from 649 feet at the James River up to 5,729 feet, offering a variety of habitats.  Its most famous residents may be the wild miniature ponies that hang out in the heath balds around Mt. Rogers.  Like George Washington National Forest, there are several types of rare salamanders found here, including the golden pygmy salamander.  Noteworthy mammals are white-tailed deer, black bears, bobcats, raccoons, river otters, martens, and weasels.  Large birds found in Jefferson National Forest include wild turkeys, turkey vultures, bald eagles, peregrine falcons, and several types of hawks.

Spring and early summer are a great time to visit to see blooming azalea, mountain laurel, and rhododendron bushes.

Peak Season

Spring and fall

Fees

$5 day-use fee at Beartree Recreation Area

Road Conditions

The Peaks of Otter Visitor Center on the paved Blue Ridge Parkway is managed by the National Park Service adjacent to Jefferson National Forest.  There are unpaved roads scattered throughout the mountains, including a rough road off Forest Road 606 that comes close to the 15-foot-tall Falls of Dismal (also accessible by hiking trail).

Camping

Beartree, Hurricane, Cane Patch, Laurel Falls, Cave Springs, Bark Camp Lake, Cave Mountain Lake, Pines, and White Rocks are only a selection of the many designated campgrounds in Jefferson National Forest.  There is a 25-foot right-of-way for backpack camping on both sides of the Virginia Creeper Trail, except on private property.

Hawai‘i Volcanoes National Park

Hawai‘i Volcanoes National Park

Hawai‘i

Managed by National Park Service

Established 1916

344,812 acres

Website: nps.gov/havo

Overview

Hawai‘i National Park was created in 1916, before being split in 1961 into this park on the Big Island of Hawai‘i and Haleakala National Park on Maui.  Encompassing two of the world’s most active volcanoes (Kīlauea and Mauna Loa), Hawaiʻi Volcanoes National Park is constantly changing.  Indigenous people considered Kīlauea Caldera and its bubbling Halemaʻumaʻu Crater as the sacred home of Pele, goddess of the volcano.  This area first became a tourist attraction in the 1840s when Volcano House was still a grass shack.  A small, wooden hotel was built in 1877 that now serves as Volcano Art Center Gallery, before the larger lodge was finished in the 1940s on the edge of the caldera.  A strenuous backpacking trail summits the world’s largest shield volcano, 13,677-foot Mauna Loa, which erupted in 1926, 1942, 1950, 1984, and 2022. 

To learn more about the separate Kahuku Unit and how to find solitude in this National Park that saw 1.6-million visitors in 2023, check out our expanded 2nd edition of our guidebook A Park to Yourself: Finding Solitude in America’s 63 National Parks

Highlights

Volcano Art Center, Halemaʻumaʻu Crater, Chain of Craters Road, Kīlauea Iki Crater, Nāhuku (Thurston Lava Tube), Hōlei Sea Arch, Lava Tree Molds, Mauna Loa Overlook, Kīpukapuaulu Trail, Pu‘u Loa Petroglyphs Trail

Must-Do Activity

Arrive early or late at the visitor center to avoid tour bus crowds, then check with a ranger to find the best overlooks to view any volcanic activity in Halemaʻumaʻu Crater (depicted in our illustration below).  Consider returning to view the molten lava after dark, although parking can be a challenge.  The Chain of Craters Road leads 20 miles south from the forested caldera rim above 4,078 feet in elevation down to the sparsely vegetated seashore, descending through a wide range of environments before it dead ends into recent lava flows near the Hōlei Sea Arch and 1.5-mile Pu‘u Loa Petroglyphs Trail, where the crisp images chipped into the black lava have been spared from centuries of volcanic activity. 

Best Trail

Kīlauea Iki Trail makes a four-mile loop descending 400 feet to the bottom of the crater that was a lake of lava in 1959.  It is recommended to hike it in a counter-clockwise direction to avoid ascending the steepest sections. 

Instagram-worthy Photo

Kīlauea erupted nonstop from 1983 through 2018, when lava poured in a near constant stream into the ocean, and it has been sporadically active since then.  Lava made it into the #1 spot on our Top 10 Natural Phenomena to See in the U.S.

Peak Season

Year round or whenever a volcano is active

Hours

https://www.nps.gov/havo/planyourvisit/hours.htm

Fees

$30 per vehicle or America the Beautiful pass

Road Conditions

Chain of Craters Road is paved, but can be closed during volcanic eruptions, just as half of Crater Rim Drive has been closed since March 19, 2008.  The side road to Hilina Pali Overlook is usually closed beyond Kulanaokuaiki Campground.  The one-lane, potholed Mauna Loa Road is doable with a passenger vehicle if you take it slow, as is the unpaved road into the western Kahuku Unit. 

Camping

The name of Kulanaokuaiki Campground translates as “shaking earth,” and this nine-site primitive camp has no drinking water, unlike the concessionaire-run Nāmakanipaio Campground and Cabins on Highway 11.  Even though this is Hawai‘i, bring some warm clothes as it can be quite rainy and windy, especially when the volcano is erupting; the temperature around Halemaʻumaʻu Crater did not rise above 59°F all day during our 2023 visit.

Mono Basin National Scenic Area

Mono Basin National Scenic Area

California

Managed by U.S. Forest Service, Pacific Southwest Region

128,303 acres

Website: https://www.fs.usda.gov/detail/inyo/specialplaces/?cid=stelprdb5129903

Overview

Established in 1984, this portion of Inyo National Forest is a geological wonderland that was once part of the former Mono National Forest.  Along the edge of this ancient salt lake are ten-foot-tall tufa towers exposed after water levels dropped beginning in 1941 when river water was diverted to Los Angeles.  Tufa is limestone that precipitated when the alkaline lake water combined with calcium from underground springs.  Paoha Island in the center of Mono Lake is also a nesting area for snowy plovers and California gulls, giving its salty waters even more of a Pacific Ocean impression.  This entire region is volcanically active as evidenced by isolated hot springs, cinder cones that erupted as recently as 350 years ago, and the forest devastation caused by a 1989 release of carbon dioxide from Horseshoe Lake.  It is also rich in minerals, showcased by the mines at Bodie State Historic Park, a ghost town conserved in “arrested decay.” 

Highlights

Mono Basin National Forest Scenic Area Visitor Center, film, Mono Lake Tufa State Natural Reserve, Panum Crater, Mono Craters, Bodie State Historic Park, South Tufa Trail

Must-Do Activity

Open May through October, the Mono Basin National Forest Scenic Area Visitor Center is located on Highway 395, just east of Tioga Pass (the eastern entrance to Yosemite National Park).  It features interactive displays on geology and human history, the 20-minute film Of Ice and Fire: A Portrait of the Mono Basin, photo exhibits, and a bookstore.  Situated atop a hill on the lake’s western shore, it offers an overlook of Mono Lake, Paoha Island, and the Mono Craters.

Best Trail

On the lake’s south side is the fascinating Mono Lake Tufa State Natural Reserve, established in 1981.  A short trail leads from the unpaved parking area to the shoreline.  Just to the west, the 0.7-mile Plug Trail enters the cone of Panum Crater, a 650-year-old plugged dome volcano.

Instagram-worthy Photo

The fragile tufa formations are a great resting place for violet-green swallows and other migratory birds that come to feed on the lake’s abundant brine shrimp and alkali flies.

Peak Season

Summer

Fees

$3 per person at South Tufa Trail or America the Beautiful pass; $8 per person to enter Bodie State Historic Park

Road Conditions

There are well-graded dirt roads to Panum Crater, South Tufa, and Bodie State Historic Park.  However, the routes on the north and east sides of Mono Lake are loose sand that require a four-wheel-drive vehicle.

Camping

There are campgrounds at June Lake and along Highway 120 to Tioga Pass, but that road is closed in the winter.  Dispersed camping is allowed in Inyo National Forest, but be careful on the sandy roads around Mono Lake.

Inyo National Forest

Inyo National Forest

California, Nevada

Managed by U.S. Forest Service, Pacific Southwest Region

2,048,459 acres (1,948,726 federal/ 99,733 other)

Website: https://www.fs.usda.gov/inyo

Overview

Inyo National Forest was established by President Teddy Roosevelt in 1907 to accommodate the Los Angeles Aqueduct, so it is mostly sagebrush slopes without much dense forest cover.  We added it to our Top 10 Movies Filmed in National Forests after reading its history as a filming location.  Inyo National Forest offers the shortest route to Mt. Whitney, the tallest peak in the contiguous U.S. at 14,495 feet in elevation.  Its proximity to Badwater Basin (282 feet below sea level) in Death Valley National Park makes its rise all the more impressive.  You will need a permit to summit, since this popular peak lies within Sequoia National Park.  One added benefit is you will learn all about how to use a “W.A.G. bag.”  In addition to accessing the eastern Sierra Nevada (see Best Trail), Inyo National Forest also offers a portal to the beautiful White Mountains along the California-Nevada border (see Must-Do Activity) and 800,000 acres of designated Wilderness. 

Highlights

Mono Basin National Scenic Area (see our blog post), Lee Vining Canyon Scenic Byway, Tioga Pass, Ancient Bristlecone Pine Forest, Convict Lake, Hot Creek Geologic Site, Mammoth Lakes, Minaret Summit Vista, Crystal Lake, Mt. Whitney Trail, Minaret Falls, Pacific Crest National Scenic Trail

Must-Do Activity

In the White Mountains, a paved road leads to the U.S. Forest Service visitor center at the Ancient Bristlecone Pine Forest, where a 4.5-mile loop trail through the Methuselah Grove passes one live Great Basin bristlecone pine tree recorded at over 5,000 years of age.  That ranks it as the oldest living single-stem tree on the planet based on annual tree-ring measurements.  You can continue to drive above 11,000 feet in elevation along a narrow gravel road famous for puncturing tires (so bring a spare).  The route offers awesome views of the Owens Valley and Mt. Whitney, then takes you to the Patriarch Grove, a wonderful park of gnarled Great Basin bristlecone pine trees surrounded by snow throughout the summer. 

Best Trail

Onion Valley Road west of Independence dead ends at the trailhead for Kearsarge Pass in the Sierra Nevada.  The trail is a series of endless switchbacks that lead past beautifully twisted foxtail pines and unbelievably blue lakes up to the 11,823-foot pass at the boundary with Kings Canyon National Park.  The view from the pass is worth the effort, even if you do not proceed to enter the National Park, for which you need a permit to camp overnight.  John Muir called these mountains “the range of light,” and from up here you will surely see why. 

Watchable Wildlife

Inyo National Forest is on the rain-shadow side of the Sierra Nevada, so it generally receives less precipitation throughout the year than the western slopes, especially at lower elevations.  In the conifer forests of the mountains look for mule deer, black bears, weasels, martens, mountain lions, and bobcats.  California quail, mountain quail, sooty grouse, and wild turkeys are common game birds.  Watch the skies for raptors like bald eagles, ospreys, red-tailed hawks, and turkey vultures.

Sun-streaked and wind-blasted branches of bristlecone pine trees twist in backbreaking curls, stretching up towards the deep blue skies above 10,000 feet elevation.

Peak Season

Summer

Fees

There are no day use fees to our knowledge.

Road Conditions

The road is paved to the trailhead for the 4.5-mile loop through the Methuselah Grove in the Ancient Bristlecone Pine Forest.  The unpaved road beyond is famous for puncturing tires (so take it slow and bring a spare) and retains snow late into the summer.  A shuttle ticket or camping permit is required to drive into the National Forest west of the ski resort town of Mammoth Lakes to access Devils Postpile National Monument.

Camping

Grandview Campground near the Ancient Bristlecone Pine Forest lives up to its name.  There is a campground at Whitney Portal Trailhead and two on Onion Valley Road on the way to the trailhead for Kearsarge Pass (plus some epic dispersed campsites).

Gunnison National Forest

Gunnison National Forest

Colorado

Managed by U.S. Forest Service, Rocky Mountain Region

1,766,941 acres (1,671,941 federal/ 95,000 other)

Website: https://www.fs.usda.gov/gmug

Overview

Gunnison National Forest surrounds the town of Crested Butte, a prime destination for mountain bikers and winter sports enthusiasts.  It also shares mountainous borders and four of its eight designated Wilderness areas with neighboring Rio Grande, San Isabel, Uncompahgre, and White River National Forests.  It was originally called the Cochetopa Forest Reserve, created by President Teddy Roosevelt on June 13, 1905.  It is now co-managed with the Grand Mesa and Uncompahgre National Forests.

Highlights

Silver Thread Scenic Byway, Slumgullion Slide, Mt. Emmons Iron Bog, Taylor Park Reservoir, San Luis Peak, Fossil Ridge Recreation Area, Gothic Research Natural Area, Judd Falls, Alpine Tunnel, Mineral Creek Trail

Must-Do Activity

Much of the area was mined in the past, so there are many miles of four-wheel-drive roads to explore over mountain passes like Tomichi, Hancock, Taylor, Tincup, and Pearl Pass.  Near the Victorian-era town of Lake City, the famous Slumgullion Slide crosses Highway 149 where a massive earth flow created Lake San Cristobal about 700 years ago.  Visible from a pullout at Windy Point, a secondary flow of sludgy montmorillonite continues to move trees downslope to this day.

Best Trail

Just past the Bureau of Land Management (BLM) recreation site at Needle Rock, a gravel road enters Gunnison National Forest where two trailheads afford entrance into the West Elk Wilderness.  Throughline Trail heads northeast toward 12,719-foot Mt. Gunnison, but it can be connected with the Lone Pine Trail at the 3.5-mile point to form a loop with Sink Creek Trail (a total of 13 miles roundtrip).  We hiked a portion of Sink Creek Trail in late September when the aspen trees were changing colors and found a nice place for dispersed camping near the South Smith Fork Trailhead (high-clearance vehicle recommended).

Watchable Wildlife

There are presumably elk in the mountainous West Elk Wilderness, as well as mule deer and bighorn sheep (a herd overwinters near the junction of the East and Taylor Rivers).  Mountain lions, black bears, and pine martens also inhabit Gunnison National Forest.  On our hikes we came across a gopher snake and a dam built by a beaver.  Watch the skies for raptors like golden eagles, red-tailed hawks, and peregrine falcons.

Instagram-worthy Photo

A good gravel road east of Crawford leads into Gunnison National Forest past Needle Rock Outstanding Natural Area, run by the Bureau of Land Management (BLM).  The landmark is a 28-million-year-old volcanic plug which can be explored on a steep trail that does not completely circle it because of private land.

Peak Season

Summer and fall

Fees

None

Road Conditions

Several paved highways crisscross the National Forest, including a stretch of the Silver Thread Scenic Byway.  Not every back road requires a high-clearance vehicle, as good graded roads go over Kebler Pass, Ohio Pass, and Cumberland Pass into the town of Pitkin.  Popular four-wheel-drive routes include Pearl Pass Road, Old Monarch Pass Road, and Schofield Pass north into Crystal Canyon. 

Camping

There are many nice campgrounds in Gunnison National Forest, including Slumgullion Campground at 11,200 feet, Lost Lake Campground next to a wildflower meadow, and Dorchester Campground on the road to 11,928-foot Taylor Pass (accessible by four-wheel-drive vehicles).  Dispersed camping is also allowed throughout the National Forest; we found a nice spot near the South Smith Fork Trailhead (high-clearance vehicle recommended).
