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.

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.

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.

Thunder Basin National Grassland

Thunder Basin National Grassland

Wyoming

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

547,499 acres

Website: https://www.fs.usda.gov/r02/mbrtb/recreation/thunder-basin-national-grassland-0

Overview

Thunder Basin is part of the Powder River Basin situated between the Big Horn Mountains and the Black Hills.  Elevations in the National Grassland range from 3,600 to 5,200 feet in the transition zone between the Great Plains and sagebrush steppe.  It was established in 1960 and is currently managed along with Routt and Medicine Bow National Forests.  Its acreage is interspersed with private inholdings and areas run by the Bureau of Land Management.

Highlights

Weston Recreation Area, Soda Well Picnic Site, reservoirs

Must-Do Activity

Although Thunder Basin National Grassland is mostly undeveloped for tourists, Weston Recreation Area is located 30 miles north of Gillette off Highway 59 with at least 15 miles of Off-Highway Vehicle (OHV) trails.  Fishing for warm water species like smallmouth bass and bluegill is possible at the following reservoirs: East Iron Creek, Kellogg, Little Powder, Little Thunder, Turner, and Weston (where there is a vault toilet).  There is a picnic shelter at Soda Well, site of the ghost town of Weston, Wyoming. 

Best Trail

The East Upton Trailhead and Kellogg Trailhead are both located in the northeastern-most corner of the National Grassland about two miles north of Upton.  Generally, it is possible to hike cross-country wearing sturdy boots to avoid hidden prickly pear and hedgehog cacti.  Be sure to wear bright colors during the various hunting seasons.

Watchable Wildlife

On our March visit to Thunder Basin National Grassland, we saw pronghorn, elk, and mule deer out grazing on the prairie.  Small rodents are prevalent, including white-tailed jackrabbits, cottontail rabbits, kangaroo rats, thirteen-lined ground squirrels, and black-tailed prairie dogs, a keystone species whose burrows create habitat for burrowing owls, prairie rattlesnakes, mountain plovers, and endangered black-footed ferrets.  Predatory mammals found here include the swift fox, red fox, badger, and coyote.   Sagebrush cover may support sage grouse, a species of management concern.

Photographic Opportunity

Early spring is a great time to visit to see large ungulates before they migrate to higher elevations and to hear the first mating calls of meadowlarks.

Peak Season

Spring

Fees

None

Road Conditions

The unpaved roads we drove were graded and accessible to passenger vehicles, but that is probably not the case when they are wet.

Camping

There are no developed campgrounds in this National Grassland, but dispersed camping is allowed on public land so use the app or get a good map to make sure you are not on the private land parcels interspersed throughout.  The Forest Service website recommends camping along Forest Road 1246.

Mark Twain National Forest

Mark Twain National Forest

Missouri

Managed by U.S. Forest Service, Eastern Region

3,012,464 acres (1,491,840 federal/ 1,520,624 other)

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

Overview

In the 1970s, the more northerly Clark National Forest in Missouri was administratively combined with Mark Twain National Forest, encompassing 11% of the state’s forests across 29 counties.  Much of the forest was planted by the Civilian Conservation Corps (CCC), with their work still visible at the Rolla Ranger Station and Winona Ranger Station Historic Districts.  Spread across nine separate units throughout southern Missouri’s Ozark Mountains, Mark Twain National Forest’s Karst topography is full of caves, sinkholes, streams, and springs.  Greer Spring is the second largest in Missouri with a daily flow of 222-million gallons as it drains 1.25 miles into the Eleven Point National Scenic River.  Greer Spring is accessible by a one-mile trail downhill from Highway 19, but no fishing or wading is allowed.

Highlights

Glade Top Trail Scenic Byway, Blue Buck Knob Scenic Byway, Greer Spring, Table Rock Lake, Council Bluff Recreation Area, Overcup Oak Sink, Silver Mine Recreation Area, Bellevue Trail, Cedar Creek Trail, Devil’s Backbone Trail, Ridge Runner National Recreation Trail, Big Piney Trail, Ozark Trail

Must-Do Activity

Most trails in Mark Twain National Forest are open to hikers, mountain bikers, and equestrians, including Ridge Runner National Recreation Trail that totals 33 miles.  Two areas at Chadwick and Sutton Bluff are designated for ATV, UTV, and motorcycle use.  Fishing is a popular activity on the Eleven Point National Scenic River and numerous lakes, like Noblett Lake and Table Rock Lake.  There are so many recreation areas spread around this massive National Forest, it is impossible to cover them all here.  We recommend you start with one of the spots listed under Highlights above.

Best Trail

Mark Twain National Forest has several long trails that explore its 78,000 acres of Wilderness areas, including sections of the 350-mile Ozark Trail.  Northeast of Branson, Hercules-Glades Wilderness protects 12,413 acres of forested hillsides, limestone outcroppings, and glades of native grasses.  There are three trailheads on the edge of the Wilderness, but we chose Blair Ridge because of its paved access 5.3 miles off Highway 160.  From a small roadside parking area, the trail follows a ridgeline for 1.2 miles to some excellent backpacking campsites that overlook the countryside before it drops 600 feet in the next mile.  At that point the trail intersects with Coy Bald Trail, which can be taken a short distance to a small scenic waterfall on Long Creek.

Watchable Wildlife

The Ozark Mountains provide habitat for common eastern species like white-tailed deer, wild turkeys, gray squirrels, cottontail rabbits, red foxes, and raccoons.  You may also encounter venomous copperheads, timber rattlesnakes, and pygmy rattlesnakes.  The oak savannahs are home to several endemic plants, as well as prickly pear cacti and animals more associated with the Southwest U.S., like roadrunners, collared lizards, scorpions, and tarantulas.  Gamefish include smallmouth bass, largemouth bass, rock bass, walleye, and rainbow trout.

Photographic Opportunity

Between Jefferson City and Columbia, Pine Ridge Recreation Area accesses Cedar Creek Trail, which has multiple trailheads and four loops totaling 36 miles.

Peak Season

Spring and fall

Fees

There are day use fees at several sites, including $5 at Noblett Lake and $2 at Blue Hole Trailhead and North Fork Recreation Area

Road Conditions

Many of the curvy back roads in Mark Twain National Forest are paved, such as Blair Ridge that led to a trailhead 5.3 miles off Highway 160.  There are likely some rough unpaved roads in the Ozarks, so check road conditions before departing.

Camping

There are numerous campgrounds in Mark Twain National Forest, although it can be harder to find good dispersed campsites due to the proximity to private land.  In the northernmost area outside Columbia, we paid to camp in the quiet Pine Ridge Recreation Area.  On the edge of the Hercules-Glades Wilderness at the Hercules Tower (with restrooms) and Coy Bald Trailheads, there are a handful of car camping sites for free.

Manti National Forest

Manti National Forest

Utah

Managed by U.S. Forest Service, Intermountain Region

735,358 acres

Website: https://www.fs.usda.gov/r04/manti-lasal

Overview

Manti Forest Reserve dates back to 1903, becoming a National Forest four years later and expanded in 1915 with the addition of Nebo National Forest.  Despite being separated by more than 100 miles, Manti and La Sal National Forests were combined in 1949, an early example of improved bureaucratic efficiency by the Forest Service.  Due to this longstanding association, it can be difficult to find information for the more northerly Manti National Forest alone.  Manti National Forest covers much of the Wasatch Plateau and also manages the busy Maple Canyon Trail system (technically in Uinta National Forest).

Highlights

Energy Loop, Skyline, Eccles Canyon, Drive Scenic Backway, Stuart Guard Station National Historic Site, Electric Lake, Nelson Mountain, Maple Canyon, Fish Creek National Recreation Trail, Left Fork of Huntington Creek National Recreation Trail

Must-Do Activity

Many visitors to Manti National Forest drive the Energy Loop, named for Utah’s coal country, which partially follows the paved Huntington and Eccles Canyons Scenic Byway.  Campgrounds, historic sites, reservoirs, trails, and trout streams are all accessible along the 86-mile drive.  The more adventurous can take on the unpaved Skyline Drive Scenic Backway that climbs the Wasatch Plateau.  This 58-mile route has many side roads popular with ATV and OHV drivers, and it is open to snowmobiles in the winter. 

Best Trail

Easily accessible from the Energy Loop drive, the six-mile long Left Fork of Huntington Creek National Recreation Trail follows the canyon gaining 847 feet in elevation.  It can be completed one-way downhill from Miller Flat Trailhead by leaving a vehicle at Forks of Huntington Campground.  Despite a wildfire on the south canyon wall and subsequent erosion, the creek remains a good fishing spot, especially the lower half-mile that has interpretive signs on hydrology for children.  The trail can also be joined with Horse Canyon, Scad Valley, and Mill Canyon Trails to form longer loops, but a vehicle shuttle would still be necessary to avoid walking the highway.  Nearby, Fish Creek National Recreation Trail is ten miles long and open to travel by foot, horse, and bicycle.

Watchable Wildlife

The Wasatch Plateau rises from 5,000 to over 10,000 feet in elevation, and its vertical escarpments and subalpine lakes support a diversity of habitats.  Huntington Creek is one of the premiere fly-fishing streams in Utah.  Joe’s Valley is a 1,200-acre reservoir that offers fishing for splake, and allows motor boats (as does Electric Lake).  Large mammals found here include black bears, mountain lions, bobcats, coyotes, elk, mule deer, and pronghorns.  Birds of Manti National Forest include bald eagles, golden eagles, northern goshawks, turkey vultures, wild turkeys, common ravens, and various species of owls and woodpeckers. 

Photographic Opportunity

Fremont cottonwood trees are named for explorer John C. Fremont and this riparian species is an indicator of permanent subsurface water, with trunks that can reach more than four feet in diameter.
