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

Summer

Fees

A day use fee applies at Lake Sherwood Recreation Area.

Road Conditions

Most roads are open year-round, including the paved road to the top of Spruce Knob when it is snow-free.

Camping

The National Forest has 23 campgrounds, including popular options in Spruce Knob-Seneca Rocks National Recreation Area at Seneca Shadows and Big Bend (with hot showers).

Sáttítla Highlands National Monument

Sáttítla Highlands National Monument

California

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

Established 2025

224,676 acres

Website: https://www.fs.usda.gov/visit/national-monuments/sattitla-highlands-national-monument

Overview

In the northeast corner of California is the largest shield volcano in North America: 7,921-foot Medicine Lake Volcano.  Sáttítla Highlands National Monument is spread across Klamath, Shasta, and Modoc National Forests just south of Lava Beds National Monument and features numerous cinder cones and lava fields.  Part of the Volcanic Legacy Scenic Byway loops around Medicine Lake, which the Modoc people view as a place of healing.  The Pit River Tribe opposed development of geothermal energy sources in this area, spearheading its protection.  In the 1960s, NASA astronauts trained at Pumice Crater, four of whom eventually landed on the moon.  Sáttítla Highlands National Monument is also important for biodiversity, providing habitat for wildlife species like the Cascades frog, long-toed salamander, and gray-headed pika, as well as numerous fungi, the parasitic sugarstick plant, and Pacific fuzzwort (a rare liverwort).

Highlights

Medicine Lake Recreation Area, Giant Crater lava tube, Glass Mountain, Black Lava Butte, Fourmile Hill Tree Molds Geologic Area

Must-Do Activity

Most of the developed recreation opportunities surround Medicine Lake, which offers boat ramps, trails, and campgrounds.  Giant Crater has the longest known lava tube system in the world at 18 miles, although it is partially collapsed.  This Geologic Special Interest Area can be accessed two miles off Medicine Lake Road on Forest Road 43N11.  Another unpaved road leads up Glass Mountain, which has a crater full of sharp pieces of rhyolite obsidian and glossy dacite.  This remote corner of California has some of the darkest skies in the continental U.S., so it is great for stargazing on moonless nights.  In the winter, snowmobiling and cross-country skiing are popular activities on groomed trails. 

Best Trail

There is a 4.4-mile loop around Medicine Lake, as well as the one-mile out-and-back Medicine Lake Glass Flow Trail that gains 68 feet of elevation on the north shore.  For a more challenging route, Little Mt. Hoffman Trail gains 666 feet over three miles to the fire lookout, which can be rented overnight.  Summitting the actual Mt. Hoffman is over 13 miles roundtrip with a 2,000-foot cumulative climb.

Photographic Opportunity

Sáttítla literally translates as “obsidian place” and the volcanic glass prevalent at Glass Mountain has provided humans sharp blades for at least 5,000 years.

Peak Season

Summer

Fees

$5 per vehicle (or the America the Beautiful Pass) at Medicine Lake

Road Conditions

This area receives abundant winter snowfall, and roads can be blocked by snow into July, which we experienced trying to get to Glass Mountain.  The road to Medicine Lake is paved, but almost every other road through the National Monument is unpaved, some requiring a high-clearance vehicle. 

Camping

There are multiple Forest Service campgrounds on Medicine Lake, plus two nearby at Blanche Lake and Bullseye Lake.  Dirt roads in Modoc, Shasta, and Klamath National Forests have ample dispersed camping opportunities.

Modoc National Forest

Modoc National Forest

California

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

1,979,327 acres (1,663,401 federal/ 315,926 other)

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

Overview

In the northeast corner of California, Modoc National Forest contains the largest shield volcano in North America: 7,921-foot Medicine Lake Volcano.  This region has a long history of volcanism, as seen at Pumice Stone Mountain, Burnt Lava Flow, High Hole Crater, Hot Spot, and Glass Mountain (composed of rhyolite obsidian and glossy dacite).  The basalt-topped plateau of Devil’s Garden is home to an 800-acre stand of western juniper.  East of Goose Lake, the Warner Mountains rise from 4,300 feet to 9,892-foot Eagle Peak, and are covered by a mixed conifer forest of lodgepole pine, whitebark pine, ponderosa pine, incense-cedar, and red fir.

Highlights

Sáttítla Highlands National Monument, Volcanic Legacy Scenic Byway, Medicine Lake Recreation Area, Glass Mountain, Devil’s Garden Natural Area, Mill Creek Falls, Highgrade National Recreation Trail, Pine Creek Trail

Must-Do Activity

Medicine Lake offers boat ramps, trails, and campgrounds and nearby is Giant Crater, which has the longest known lava tube system in the world at 18 miles (although it is partially collapsed).  Located up a dirt road often blocked by snowdrifts late into the summer, Glass Mountain has a crater full of sharp pieces of rhyolite obsidian and glossy dacite.  This remote corner of California has some of the darkest skies in the continental U.S., so it is great for stargazing on moonless nights.  In the winter, snowmobiling and cross-country skiing are popular activities on groomed trails.  The South Warner Mountain Wilderness is traversed by the 21-mile Summit Trail that passes Eagle Peak, the Devil’s Knob, and The Slide. Mill Creek Falls is also in the Warner Mountains, accessed by a 3.4-mile out-and-back trail.

Best Trail

In the Warner Mountains near the border with Oregon’s Fremont National Forest, the 5.5-mile one-way Highgrade National Recreation Trail provides excellent views of Goose Lake.  The trailhead is reached by taking paved County Road 9 five miles east from Highway 395 then turning north on the steep and unpaved Del Pratt Spring Road (Forest Road 47N72) for 6.3 miles.  The trail quickly leaves the shade of the forest as it steadily climbs 800 feet through a slope covered in woolly mule’s ears flowers to a saddle west of 8,224-foot Mt. Vida.  It is possible to summit Mt. Vida from this point, but the trail heads away toward Yellow Mountain following Forest Road 48N10.

Watchable Wildlife

Modoc National Forest borders Lower Klamath National Wildlife Refuge, in addition to Tule Lake, Clear Lake, and Modoc National Wildlife Refuges.  These wetlands provide habitat crucial for bird nesting and migration on the Pacific Flyway.  The many lava tubes provide habitat for numerous species of bats, in addition to violet-green swallows and bushy-tailed woodrats.  Larger mammals include mule deer, pronghorn, badger, skunk, raccoon, pika, jackrabbit, yellow-bellied marmot, coyote, bobcat, and mountain lion.  Large birds found here are great horned owl, short-eared owl, and bald eagle (winter resident).  Reptiles are abundant, including the western fence lizard, northern sagebrush lizard, western skink, Rocky Mountain rubber boa, gopher snake, desert night, and western rattlesnake.

Photographic Opportunity

Not far up the steep Highgrade National Recreation Trail there are excellent views of Goose Lake to the west.

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.

Peak Season

Summer

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 motorcycles and OHVs, so keep an eye out for them while driving. 

Camping

Mendocino National Forest manages Bear Creek Campground and Lower Nye Dispersed Campground among many others, plus there are countless places for dispersed camping.

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.
