John D. Rockefeller, Jr. Memorial Parkway

John D. Rockefeller, Jr. Memorial Parkway

Wyoming

Managed by National Park Service

Established 1972

23,777 acres

Website: https://www.nps.gov/grte/planyourvisit/jodr.htm

Overview

John D. Rockefeller, Jr. Memorial Parkway shares 82 miles of two-lane road that is U.S. Routes 89, 191, and 287 from Grand Teton National Park National Park north to West Thumb Geyser Basin in Yellowstone National Park.  Its name honors the conservationist and philanthropist who contributed to the creation of Acadia, Grand Teton, Great Smoky Mountains, and Virgin Islands National Parks.  Originally part of Teton National Forest, this land includes the Flagg Ranch concession, which had its lodge, restaurant, gas station, and campground moved from along the Snake River to a point less visible from the road in 2002. 

Highlights

Flagg Ranch, Huckleberry Hot Springs, Polecat Hot Springs

Must-Do Activity

Huckleberry and Polecat Hot Springs are easily accessed by walking less than a mile down a closed dirt road not far from historic Flagg Ranch.  Polecat Creek Loop Trail can be completed as a 2.5-mile loop that is narrow and overgrown by vegetation in places.  Be on the lookout for grizzly bears, black bears, elk, and moose.  Trout fishing in the Snake River is also a popular activity in John D. Rockefeller, Jr. Memorial Parkway.  The parkway is plowed to Flagg Ranch in the winter, making it a shared trailhead for snowmobilers, snowshoers, and cross-country skiers. 

Best Trail

Flagg Canyon Trail is a five-mile out-and-back hike along the Snake River with 340 feet of cumulative elevation gain after it crosses the busy parkway east of Flagg Ranch.

Photographic Opportunity

Driving unpaved and potholed Grassy Lake Road provides views to the south of the Teton Range.

Fees

Grand Teton or Yellowstone National Park entrance fees apply (or America the Beautiful pass)

Road Conditions

The parkway is paved and closes for the winter at Flagg Ranch when the south entrance to Yellowstone National Park shuts down.  Closed annually for grizzly bear migration until June 1, Grassy Lake Road heads 49 miles west to Ashton, Idaho (the easternmost 36 miles are a potholed dirt track for high-clearance vehicles that enters Targhee National Forest, which is popular for dispersed camping).

Camping

There is a lodge at Flagg Ranch, plus Headwaters Campground takes reservations and offers 34 tent sites, 97 full-hookup RV sites, and 40 Camper Cabins (open June 7 to October 4, 2026).  Along rough Grassy Lake Road there are eight free camp areas with 14 first-come, first-served campsites equipped with vault toilets and bear boxes.  There are also campgrounds in Teton National Forest and primitive dispersed campsites near Grassy Lake once the road enters Targhee National Forest.

Monongahela National Forest

Monongahela National Forest

West Virginia

Managed by U.S. Forest Service, Northern Region

1,706,898 acres (921,150 federal/ 785,748 other)

Website: https://www.fs.usda.gov/r09/monongahela

Overview

Monongahela National Forest contains the highest point in West Virginia, 4,863-foot-tall Spruce Knob with an observation tower for seeing over the trees at its summit.  It is part of Spruce Knob-Seneca Rocks National Recreation Area (see our full blog post), which is very popular with rock climbers.  The National Forest’s initial 7,200 acres were purchased by the federal government in 1915, and it the grew to 150,367 acres over the next decade.  During World War II, the U.S. Army utilized the area as an artillery and mortar range, in addition to training soldiers in climbing techniques at Seneca, Nelson, and Champe Rocks.  This area receives an average of 60 inches of annual precipitation on the west side of the Allegheny Front and only half that on the rain shadow side.  It is the headwaters of six major rivers: the Monongahela, Potomac, Greenbrier, Elk, Tygart, and Gauley.

Highlights

Spruce Knob-Seneca Rocks National Recreation Area, Cranberry Glades Botanical Area, Highland Scenic Highway, Lake Sherwood Recreation Area, Gaudineer Knob Scenic Area, Cassell Cave, Sinks of Gandy, Stuart Memorial Drive, Champe Rocks, Dolly Sods Scenic Area

Must-Do Activity

There are 94,991 acres in eight designated Wildernesses in Monongahela National Forest, more than half of which is in the Cranberry Wilderness.  A boardwalk traverses the bogs at Cranberry Glades Botanical Area, which has a visitor center run by the Forest Service.  Fishing is a popular pastime, especially at Lake Sherwood, Spruce Knob Lake, and Lake Buffalo.  When winter conditions are right, there is a snowmobile area on Highland Scenic Highway.  The forest is mostly second growth, but 318 acres of old-growth remains, which can be seen at Fanny Bennett Hemlock Grove, Gaudineer Scenic Area (for red spruce), Shavers Mountain Spruce-Hemlock Stand, North Fork Mountain Red Pine Botanical Area, North Spruce Mountain Old Growth Site, and Virgin White Pine Botanical Area.

Best Trail

There is great hiking in Spruce Knob-Seneca Rocks National Recreation Area, and other trails can be found at Lake Sherwood Recreation Area, Falls of Hill Creek Scenic Area, Mt. Porte Canyon, and Stuart Recreation Area.  The 17,371-acreDolly Sods Wilderness encompasses much of the Red Creek drainage with high-elevation bogs and heaths like those found in southern Canada.

Watchable Wildlife

It is hard to believe given their abundant numbers today, but in the 1930s white-tailed deer had to be reintroduced from Michigan.  In 1969, 23 fishers were reintroduced from New Hampshire.  Other large mammals include black bear, red and gray fox, coyote, bobcat, snowshoe hare, beaver, river otter, raccoon, mink, skunk, and opossum.  Of the 230 bird species identified, 159 are known to breed here.  Approximately 90% of the trout waters in West Virginia are within the National Forest, and trout are stocked at Spruce Knob Lake and other locations.

Photographic Opportunity

The iconic Seneca Rocks are a 900-foot-tall quartzite crag heavily used by rock climbers.  On October 22, 1987, a prominent pinnacle dubbed “the Gendarme” fell to the ground.

Peak Season

Mendocino National Forest

Mendocino National Forest

California

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

1,079,850 acres (911,733 federal/ 168,117 other)

Website: https://www.fs.usda.gov/r05/mendocino

Overview

Originally called California National Forest in 1908, this area between Interstate 5 and Highway 101 was renamed Mendocino National Forest 24 years later.  It stretches north-south along the Coast Range covering parts of six counties north of San Francisco.  Similar to Los Padres National Forest, it contains rocky serpentine ridgelines where only specially adapted plants can tolerate the heavy metals in the soil, like Sargent cypress and the shorter McNab cypress.  Both species can be found along Frenzel Creek near Little Stoney Campground.  In 1953, a Forest Service employee and 14 volunteer firefighters died in the Rattlesnake Fire and a memorial overlooking Rattlesnake Canyon is located off Forest Highway 7 on Alder Springs Road.  Mendocino National Forest includes the northern portion of Berryessa Snow Mountain National Monument (see our full blog post), established in 2015 and administered in cooperation with the Bureau of Land Management.

Highlights

Berryessa Snow Mountain National Monument, Lake Pillsbury, Thomes Gorge, Hull Mountain, Frenzel Creek, Harvey Peak, Ide’s Cove Trail

Must-Do Activity

There are 18 National Forests in California (the most of any state), but Mendocino is the only one not crossed by a paved highway.  It is a wonderful destination for outdoor recreation, both motorized and non-motorized, including Hull Mountain which is popular with hang gliders.  Lake Pillsbury is 2,280 acres and offers boat ramps, campgrounds, and a resort, while 35-acre Letts Lake has a campground and access to hiking trails.

Best Trail

As we drove the winding road from Stonyford to the tiny roadside pullout for Deafy Glade Trail, we passed campgrounds full of RVs that were getting ready for a motorcycle event.  Our hike took us far from any road noise, as we dropped down to and waded across the frigid South Fork of Stony Creek and then climbed steeply to 5,300 feet in elevation.  The trail continued to the summit of 7,056-foot Snow Mountain, but we already had great views of the Rice Valley and decided to turn around at the 4.5-mile point, just inside the official boundary of the Snow Mountain Wilderness.  We expected a desolate landscape after reading about recent fires, but about three-quarters of the trees along the trail were still alive and showed only minor charring at their bases.

Watchable Wildlife

Mendocino National Forest protects a biodiverse area home to tule elk, black-tailed deer, river otters, black bears, and mountain lions.  Rivers that drain these highlands are used by California coastal chinook salmon and Northern California steelhead.  Fishing in the lakes is a popular activity and a chance to see ospreys and bald eagles.

Photographic Opportunity

On Deafy Glade Trail, there were congregations of lady bugs that numbered in the hundreds along the South Fork of Stony Creek.

Road Conditions

Fouts Springs Road (Forest Road M10) is a well-maintained gravel road that crosses the National Forest west of Stonyford.  That area is popular with motorcycles and OHVs, so keep an eye out for them while driving.

Berryessa Snow Mountain National Monument

Berryessa Snow Mountain National Monument

California

Managed by U.S. Forest Service and Bureau of Land Management

Established 2015

344,476 acres

Website: https://www.blm.gov/programs/national-conservation-lands/california/berryessa-snow-mountain-national-monument

Overview

North of the San Francisco Bay and west of Interstate 5, flat-topped 7,056-foot Snow Mountain sheds water into the Berryessa Valley and the Sacramento River.  High elevations are dominated by conifers, while below there are oak-studded hillsides, canyons full of riparian trees, and rocky serpentine ridgelines where only specially adapted plants can tolerate the heavy metals in the soil.  In 2024, the 13,696-acre Molok Luyuk (“Condor Ridge” in the Patwin language) was added to the National Monument since it contains evidence of human occupation dating back more than 10,000 years.

Highlights

Cache Creek Wilderness, Knoxville Recreation Area, Nye Cabin, Prather Mill, Deafy Glade Trail, Redbud Trail

Must-Do Activity

In the portion of the National Monument run by the Bureau of Land Management, Cache Creek Wilderness is one of the main attractions for whitewater rafting and backpacking.  Redbud and Judge Davis Trailheads off paved Highway 20 provide the easiest access for hikers.  Further south, Knoxville Recreation Area encompasses rugged terrain for exploration with off-highway vehicles (OHVs).  The northern portion of Berryessa Snow Mountain National Monument within Mendocino National Forest has a network of dirt roads that are also popular with OHV riders.  In the far north, Hull Mountain is utilized by hang gliders.

Best Trail

In Mendocino National Forest, Deafy Glade Trail starts at a tiny roadside pullout along Fouts Springs Road where campgrounds were full of RVs getting ready for a motorcycle event.  Our hike took us far from any road noise, past congregations of lady bugs that numbered in the hundreds as we waded across the frigid South Fork of Stony Creek and climbed steeply to the boundary of the 60,076-acre Snow Mountain Wilderness.  The trail continues to climb 4,300 feet total to the summit over the course of eight miles.  It is half that length with only 2,000 feet of elevation gain from the west via Summit Trail, although the last 1.5 miles of the access road may be impassable to vehicles.

Photographic Opportunity

From our turnaround spot on Deafy Glade Trail we got great views of the Rice Valley. 

Peak Season

Spring

Fees

None

Road Conditions

Fouts Springs Road (Forest Road M10) is a well-maintained gravel road that crosses the National Forest west of Stonyford.  That area is popular with OHVs, so keep an eye out for them.  Further south, Highway 20 is a paved route to trailheads in Berryessa Snow Mountain National Monument, but four-wheel-drive may be required to access Buck Island Campground.  The new Molok Luyuk section northeast of Clear Lake is reached by the gravel Walker Ridge Road that requires a high-clearance vehicle.

Camping

Mendocino National Forest manages Bear Creek Campground and Lower Nye Dispersed Campground, plus numerous others outside the National Monument boundaries.  There are several campgrounds on Lake Berryessa, in addition to the ones at Clear Lake State Park and Cache Creek Canyon Regional Park.

Chamizal National Memorial

Chamizal National Memorial

Texas

Managed by National Park Service

Established 1974

55 acres

Website: nps.gov/cham

Overview

The Rio Grande forms the international border between the U.S. and Mexico for 1,248 miles, but in El Paso the river changed course suddenly in 1864 creating Cordova Island and leading to a 630-acre land dispute that lasted a century.  An 1884 treaty agreed in principle that if the river changed course slowly by erosion, then the boundary moved with the deepest channel, but a commission investigating it a decade later found that Americans were settling land owned by Mexico.  The issue remained contentious, with a 1909 meeting between Presidents Taft and Diaz almost resulted in the assassination of them both.  Finally, a 1963 settlement involved displacing 5,600 Americans, as well as moving a railroad, school, bridge, and the river channel itself.  Chamizal National Memorial was authorized by Congress three years later to celebrate the goodwill inherent to this treaty with a history museum, as well as three art galleries and a 500-seat indoor theater. 

Highlights

Museum, film, Franklin G. Smith Gallery, Benito Juarez sculpture, Nuestra Herencia mural

Must-Do Activity

There is a film shown in the visitor center, in addition to the museum about the treaty and exhibits in the art galleries that change every few months.  Summer concerts take place in the outdoor amphitheater and the Chamizal Festival is held the first weekend in October featuring music, crafts, dance, and visual arts. The park annually holds a Siglo de Oro Drama Festival in the spring, when acting troupes performed plays from the golden age of Spanish theater, including those by Lope de Vega.  In September 2025, the first Chihuahuan Desert Festival was held throughout the city of El Paso.  Check the National Park Service website or Facebook page for events throughout the year. 

Best Trail

There are walking trails around the 55-acre property that pass some of the historic boundary markers along East Paisano Drive. 

Photographic Opportunity

Nuestra Herencia is a very colorful mural painted on the outside of the visitor center.

Peak Season

Spring and fall

Road Conditions

Access roads are paved, but be careful how you get there because it is very close to a border crossing station and you do not want to accidentally wind up in Ciudad Juarez, Mexico.

Camping

There are private campgrounds in El Paso, or visit Franklin Mountains State Park for camping, hiking, mountain biking, and rock climbing opportunities.  Encompassing 24,248 acres, this is one of the largest urban parks in the country lying completely within city limits.
