In the agency’s own words

Twin Lakes Campground is located in the eastern Sierra Nevada Mountains near the town of Mammoth Lakes, California. It offers lakeside camping with breathtaking scenery and many outdoor activities. The lake is a great base for fishing, boating, viewing waterfalls and hiking, and offers close proximity to the town's amenities. Keep reading

Recreation

The eastern Sierras are known for great trout fishing, and the 108-acre lakes are a prime location for it. Anglers can cast for rainbow, brook and brown trout while watching a waterfall tumble into the lake. The calm waters are also inviting for canoes and kayaks. Power boats must have electric motors. Several trails offer a variety of hikes nearby, including a 4-mile trail on Mammoth Mountain and two shorter nature trails along the lakes. Families enjoy attending educational programs scheduled throughout the summer.

Facilities

This is a large facility with campsites split into two sections on either side of Twin Lakes. Sections 1 and 2 are on the west side, closer to the shore. Section 3 is set upon a hill. Picnic tables, campfire rings, flush toilets and drinking water are provided. Campers can walk to the facility's general store for boat rentals, camping supplies and showers.

Natural Features

The campground is forested with lodgepole pine, providing partial shade and a private setting. It sits at an elevation of 8,600 feet at the base of snow-capped, 11,059' Mammoth Mountain, a popular skiing destination. A cascading waterfall flows into one of the lakes. The mountains are abundant with wildlife, including black bear, mountain lions, mule deer, pine marten, pika and many species of fish and birds.

Nearby Attractions

Mammoth Lakes Basin contains several additional popular lakes to explore for fishing and boating, and Mammoth Mountain Ski Resort offers year-round recreation. Visitors can also access the magnificent John Muir Wilderness nearby, which stretches 100 miles along the crest of the Sierra Nevadas, a land of lofty snow-capped mountains, deep canyons and vast expanses of glacially-carved terrain. Abundant hiking and horseback riding trails are available.

Fire Restrictions: Fire restrictions may be imposed at any time due to hot, dry weather conditions, at which time campfires and charcoal fires may not be allowed. For current fire conditions or weather closures contact the Mammoth Lakes Visitor Center, (760) 924-5500, or the Mono Lakes Visitor Center, (760) 647-3044.

Rule

Please Note: One RV with tow per single site or one vehicle per tent site. Most sites can accommodate 1 extra vehicle that is not included with the reservation fee. In accordance with standard industry practices, Inyo Recreation will assess an additional $10.00 extra vehicle fee per day for the second vehicle in each single family campsite, and on the third and fourth vehicle in any double family campsite, provided these vehicles are not joined to the first vehicle by a hitch and towed onto the site. In the case of motorcycles, the first two are considered one vehicle, and the third and fourth motorcycle are also considered one vehicle. No additional vehicle fees are collected for bicycles. Extra vehicles must fit on the parking spur.

Rule

Reserved Sites will be held until checkout time (NOON) the day following your arrival date. Sites must be occupied by the checkout time of the second day to hold a reservation or the site will be forfeited and released to other guests. Please call the office at 760-934-5795 if you need to inform the campground of an arrival time greater than 24 hours after your arrival date, or if you will not use your reservation whatsoever.

Rule

Once your reservation start date has begun, neither the Recreation.gov Contact Center nor the campground manager will be able to modify your reservation.

Rule

Don't Move Firewood: Protect California's forests from tree-killing pests by buying your firewood locally and burning it on-site. For more information visit firewood.ca.gov.

Who keeps the booking fee

The agency’s own policy text says the reservation fee and the cancellation processing fee are “retained by the reservation service contractor”, and that a campground concessionaire will decline to refund them because “they did not receive these fees”. Recreation.gov is run under contract by Booz Allen Hamilton. What share of your booking fee the contractor keeps isn’t published in any federal dataset we can read, so we print no number for it.

Toilet distances are OpenStreetMap’s, measured for 39 of the 94 sites listed. A site with no reading is unknown, never far.

The price is derived by CAMPANAC, not published per site: the per-night rate this campground publishes for each site’s own site type. 93 of the 94 sites listed carry one, and a site whose type has no published rate sits out of the price rather than being called free.

Measured shade is NLCD Tree Canopy Cover 2024 (USDA Forest Service / MRLC) read at the site’s own coordinate, 27% canopy or more, and only for the sites the agency gave no Shade value. It never changes the agency’s own shaded count beside it.

How we know

every fact on this page, and where it came from

Right now: U.S. Forest Service’s own recreation database flags it not open and publishes no reason and no date. That’s a flag, not a notice: the number below is the only way to be sure.

Listed not open: USFS EDW Recreation Opportunities, openstatus field: a not-open flag in a database, with no reason and no date published; read there since Sep 9, 2026. A flag, not a notice, so this page doesn’t call it a closure. · Oct 16, 2026

Sites on recreation.gov: recreation.gov’s own month availability payload for this facility, asked for October 2026, November 2026 and July 2027. It names 93 of the 93 campsites the agency files here, and every one of them carries an answer either way. A campground nobody has read carries no answer at all, never a no. · Oct 11, 2026

Cell signal: the Forest Service’s own campground description, read as text by CAMPANAC. None of this is a measurement. It’s what the land manager published about the place, and phones, carriers and weather all disagree with each other; treat it as a warning, not a promise.
