Inyo National Forest Camping Guide: Best Hikes, Lakes & Dispersed Camping Tips
Inyo National Forest is California’s most visited national forest, and after wandering its 2.1 million acres myself, I get why it pulls so many outdoor fans back every year. This place has it all: Mount Whitney (the tallest peak in the lower 48), the ancient Methuselah tree, nine wilderness areas, and more than 1,000 miles of trails winding through wild deserts and rugged mountains.
Whether you’re looking to snag a spot at one of the 70 developed campgrounds, try some world-class hiking, paddle across alpine lakes, or just pitch a tent in the backcountry, you’ll find the basics you need for your Inyo adventure right here.
I’ve tracked down practical info about camping in all four ranger districts, permits, the hikes I think are most worth your time (from mellow family strolls to tough backcountry treks), and the lakes that steal the show. The forest’s name comes from a Native American word meaning “dwelling place of a great spirit.” Once you get out there, you’ll see why that fits.
Inyo National Forest Camping Guide: Best Hikes, Lakes & Dispersed Camping Tips
Essential Inyo National Forest Camping Guide
Inyo National Forest spreads across two million acres along California’s Eastern Sierra. Campgrounds use reservation systems, require bear-proof storage, and open or close depending on snow and elevation.
Top Campgrounds and Reservations
I usually book campsites through Recreation.gov up to six months ahead for standard sites, or up to a year for group campgrounds. Near Mammoth Lakes, Big Springs Campground has 26 sites tucked into pine forest, and Sherwin Creek Campground gives you easy trail access.
Whitney Portal makes a great base for folks climbing or hiking Mount Whitney, but those sites fill up fast in summer. Coldwater Campground is a solid pick for fishing in the Mammoth Lakes Basin. Most campgrounds allow 7-14 day maximum stays, and standard sites usually fit six people.
Some sites don’t take reservations, so I show up early if I’m hoping to grab one—especially on weekends. Most campgrounds have vault toilets and fire rings, but not all have drinking water.
Camping Essentials and Bear Safety
I always toss a first aid kit, water filter, and extra layers in the car—temperatures drop a lot at elevation in the Sierra Nevada. Bear-resistant lockers are required for all food and scented stuff, including coolers, toiletries, coffee mugs, and even air fresheners.
Bears will break into cars for food, so I never leave coolers, groceries, or anything smelly in my vehicle. I clean up right after eating and stash trash immediately. Every campsite comes with a bear-proof storage box.
I stick to the fire rings and pick up firewood on-site. If I collect dead wood, I leave standing trees alone. I always check current fire restrictions before heading out—nothing ruins a trip like an unexpected fire ban.
Best Seasons and Weather Considerations
Campground opening dates depend on snowpack, so they usually open late spring through fall. Heavy snow can push openings later, and early closures help prevent water systems from freezing. I always check the specific campground status before leaving since dates can be a moving target.
June through September is the safest bet for access, but summer afternoons sometimes bring sudden thunderstorms at higher elevations. I pack rain gear and warm clothes even in July—temps can swing 30-40 degrees between day and night. In spring, a lot of roads stay closed until June, so I plan around that.
Dispersed camping or boondocking lets you camp outside developed sites, but you won’t get any services, and you really have to follow Leave No Trace. I like dispersed sites when campgrounds are closed but the weather’s still decent.
Best Hikes and Trails in Inyo National Forest
Inyo National Forest covers more than 2 million acres, with trails for every mood: easy lakeside loops or the brutal climb up Mt. Whitney. You’ll pass alpine lakes, ancient forests, and high-altitude wilderness where you’ll need permits for overnight stays.
Top Hiking Trails for All Levels
New to hiking? Try the 2.5-mile Convict Lake Loop—just 180 feet of elevation gain, with turquoise water and mountain views. The 1.8-mile McLeod Lake Trail near Horseshoe Lake is another easy one, with 347 feet of gain.
If you want more challenge, Crystal Lake Trail is a 3.2-mile round trip with 840 feet of gain from Lake George campground. The Barney Lake Trail is 5.1 miles and hits a bunch of alpine lakes before reaching Barney Lake.
Looking for a longer day? The Little Lakes Valley Trail goes 7.2 miles with 1,033 feet of gain, passing seven different alpine lakes. Big Pine Creek takes you to seven turquoise lakes over 14.7 miles and 3,841 feet of gain, but most people turn around after the first few lakes.
Must-Do Backpacking Routes
The Mount Whitney Trail is the toughest at 21.2 miles round trip and 6,663 feet of gain. You’ll need to plan ahead and snag a wilderness permit from Recreation.gov. The trail passes Lone Pine Lake, Mirror Lake, and Consultation Lake before you hit the switchbacks up to the 14,505-foot summit.
In the John Muir Wilderness, the Big Pine Lakes Trail is a backpacker’s dream with camping at glacier-fed lakes. I like Lake #2 for overnights—the turquoise color comes from glacier silt. McGee Creek to Horsetail Creek is great for fall colors in October and is fairly mellow for multi-day trips.
Duck Pass from Mammoth Lakes Basin leads to several lakes and can stretch to 10 miles if you keep going past Barney Lake. Temple Crag towers above Big Pine, while the bristlecone pine forests near the White Mountains bring a totally different vibe.
Trail Safety, Elevation, and Permits
Permit Requirements:
- Day hikes: No permit needed (except Mount Whitney Trail)
- Overnight wilderness trips: Wilderness permit required (book up to 6 months in advance)
- Book through Recreation.gov for the busiest trails
Most trails in Inyo National Forest sit above 8,000 feet, so altitude kicks in fast. The elevation gain feels tougher than you’d expect. I always check trail maps on AllTrails and download offline versions before heading out—cell service is pretty spotty.
Weather flips fast at altitude. I bring layers, rain gear, and extra snacks even for short hikes. You can usually refill water at lakes, but I never go without a filter. Bears are everywhere, so I always use a bear canister for food when I’m camping overnight in the wilderness.
Inyo National Forest Lakes You Must See
Inyo National Forest is dotted with pristine alpine lakes tucked among granite peaks and pine forests. Some are right off the road, others take a solid hike to reach. You’ll find fishing, boating, wildlife, and even a few hot springs if you know where to look.
Iconic Alpine Lakes and Activities
The Mammoth Lakes Basin has several connected lakes you can reach by paved or dirt roads. Lake Mary is the biggest, with a boat launch and rentals. Twin Lakes and Lake George are perfect for kayaking and paddleboarding.
Convict Lake is probably the most photographed lake in the Eastern Sierra. Deep blue water, dramatic mountains rising 3,000 feet above—it’s a stunner. I fish for rainbow and brown trout from shore or rent a boat at the marina. There’s a paved trail looping the lake for a mellow walk.
June Lake Loop links four main lakes along a scenic highway. Camping options near Inyo National Forest include developed spots at several lakes. June Lake itself is great for fishing, and Gull Lake and Silver Lake give you more places to get on the water.
Best Lakes for Fishing and Boating
Long Lake in Little Lakes Valley is home to native golden and brook trout. It’s about a 3-mile hike in, but the trail’s pretty flat and the views at 10,500 feet are unreal.
Heart Lake takes more effort but rewards you with solitude and big trout. The 4-mile trail gains a lot of elevation. Mack Lake is nearby and offers good fishing with a slightly easier approach.
South Lake near Bishop works as both a trailhead and a fishing hole. You can launch a motorboat and catch rainbows or browns all summer. North Lake is just down the road—same vibe, but usually quieter.
Top Lake Hikes and Scenic Loops
Little Lakes Valley packs several alpine lakes into a short stretch. From Mosquito Flat trailhead, Mack Lake is 1.5 miles in, Long Lake is 3 miles, and you can keep going to Gem Lakes for a full day. Wildflowers pop in July and August, and you stay below treeline most of the way.
Big Pine Lakes trail climbs to seven glacier-fed lakes under Palisade Glacier. First Lake is just 2.5 miles from the trailhead, but the upper lakes are a solid 5-7 mile hike. If you’re lucky, you’ll spot pika and marmots in the rocks.
Convict Lake Loop is an easy 2.5-mile walk around the shoreline, with constant lake views and fishing access. Barney Lake is a steeper 4-mile hike from the same trailhead, gaining 1,500 feet for a quieter spot.
Unique Hot Springs and Wildlife Viewing
Hot Creek Geological Site near Mammoth gives you platforms above steaming springs and blue pools. Swimming’s off-limits (temps change fast), but it’s a wild spot to see geothermal action up close.
Wild Willy’s Hot Springs is a short hike from the road. Pools have mixing valves so you can tweak the temperature. The springs sit near Crowley Lake, where you might spot bald eagles and ospreys in winter. Bring a towel and water shoes—it’s rocky.
June Lake is a hot spot for osprey in summer. They nest on platforms around the lake and fish all day. Deer wander the shore at dawn and dusk. Skelton Lake and Arrowhead Lake near Mammoth are quieter but just as good for spotting wildlife along rocky shores.
Dispersed and Wilderness Camping Tips
Inyo National Forest lets you camp for free in primitive sites across most of the forest, but rules change by area and some zones ban camping outright. Knowing where you’re allowed, what permits to grab, and how to prep for the Sierra’s unpredictable weather will make your wilderness trip a lot smoother.
Top Areas for Dispersed Camping
Mammoth Scenic Loop is definitely one of the most accessible dispersed camping spots in Inyo National Forest. The paved road runs between Highway 395 and Mammoth Lakes, with a bunch of Forest Service roads splitting off from both sides. I usually find it pretty easy to grab a site closer to the main road if I’ve got a bigger vehicle or a trailer, but if I head farther back, the roads get rough, and there’s a lot more privacy.
Owens River Road has tons of small pullouts tucked deep in the trees. I watch out not to drive too far back, since once I hit Big Springs Campground, dispersed camping isn’t allowed anymore.
Rock Creek Road gives more options for dispersed camping, but it’s smart to check current regulations before rolling in. The Buttermilk Road area near Bishop draws climbers for its excellent bouldering, and most campsites gather around the main climbing zone. The road’s a pain for trailers or big rigs, though.
Mono Mills, right off Highway 120, has sites on both sides of the road, and the views of the Sierra and Mono Lake are just hard to beat.
Regulations, Permits, and Leave No Trace
I don’t need a permit for dispersed camping in Inyo National Forest, but there are a bunch of rules to keep in mind. The Eastern Sierra Sustainable Recreation Partnership put together an interactive map that makes it pretty clear where camping is allowed. Prohibited areas show up in red.
Land ownership is a patchwork across Inyo. The Los Angeles Department of Water and Power doesn’t allow camping on their property, so I always double-check with GPS apps that show public land boundaries to make sure I’m on National Forest land.
Here’s what I always stick to:
- Camp at least 200 feet from water
- Pick established sites if they’re there
- Keep my site small and avoid damaging plants
- Store food in bear-proof containers
- Get a California campfire permit before lighting any fire
If I’m backpacking into a designated wilderness area like the John Muir Wilderness, I need a wilderness permit. I always check the Forest Service alerts page before heading out to see if there are any closures or fire bans.
Leave No Trace matters here. I pack out all my trash, move my tent around if I’m staying more than a night, and I never leave a campfire smoldering—everything gets put out cold.
Safety, Weather, and Preparedness
Inyo National Forest stretches across wild elevation swings, from jagged alpine ridges right down to the desert’s edge. I’ve learned to expect wild weather—especially in spring and fall, when a bluebird day can suddenly turn into a snowshoe situation up high.
Summer afternoons? They often bring surprise thunderstorms above treeline. I usually start hikes like Big Pine Lakes Trail early, hoping to beat the clouds. And for winter camping, I can’t mess around—frigid temps demand real-deal cold-weather gear.
Here’s what I always toss in my pack:
- Portable water container (since there’s no water at dispersed sites)
- Bear canister for food storage
- GPS maps downloaded for offline use
- First aid kit and emergency gear
- Plenty of clothing layers for wild temperature swings
Cell signal? Forget about it—most dispersed camping spots are dead zones. I make sure to download maps and info before leaving the pavement. Aspen groves at mid-elevations give some wind shelter, but cold nights still sneak up fast.
I always let someone know where I’m camping and when I plan to return. Up here, the weather can flip in a heartbeat. A sunny morning might shift to afternoon snow, even in the middle of summer if you’re high enough.
