RV Dump Stations In Mammoth Lakes, California

Your main public option is New Shady Rest Campground in the Inyo National Forest, which has an RV dump station available for a fee, along with drinking water and flush toilets. In town, Mammoth Mountain RV Park offers full hookups and a dump station for guests. We track several dump stations in the Mammoth Lakes area. Because the forest campgrounds have no hookups and many close for winter, the simplest plan is to dump at New Shady Rest in season or stay at a full-hookup park where you can manage tanks at your site.

Not really. The dump stations around Mammoth Lakes are tied to campgrounds or charge a fee, such as the one at New Shady Rest Campground. Dispersed camping in the surrounding Inyo National Forest is free, but it offers no dumping, so you must pack out and use a town or campground dump station afterward. For the most reliable and reasonably priced dumping, plan on the fee station at New Shady Rest in season or a full-hookup private park. Free public dumps are not something to count on at this elevation.

It is difficult. Mammoth Lakes sits near 8,000 feet and gets heavy mountain snow, so most campgrounds, including New Shady Rest and their dump stations, close for the season. Winter RV camping is possible but only for the well prepared, and dump access is limited to whatever private parks stay open. If you visit in the cold months, confirm a park is operating before you arrive, choose a full-hookup site, and drain and disconnect your hose against hard freezes. For most travelers, the practical dumping season runs late spring through fall.

No, it has no electrical, water, or sewer hookups at the sites, which is typical for a national forest campground. It does provide drinking water, flush toilets, and an RV dump station for a fee, and generators are allowed between 7 a.m. and 10 p.m. The campground has 97 sites in a Jeffrey pine forest at 7,800 feet and takes RVs up to 40 feet, open roughly late May to early September with reservations on recreation.gov up to six months ahead. Plan to dry camp and use the dump station as you come and go.

New Shady Rest Campground accommodates RVs up to 40 feet, which covers most rigs, and the in-town private parks take larger coaches with full hookups. The bigger consideration is the drive: US-395 handles big rigs but involves real mountain grades at altitude, and CA-120 over Tioga Pass to Yosemite is steep, narrow in spots, and closed in winter. Take the climbs slowly, watch your engine and brakes at elevation, and fuel up before long stretches, since stations along the Eastern Sierra are spread out.

Mammoth Lakes sits off US-395, the main Eastern Sierra corridor, reached by turning west onto CA-203 into town. There are no nearby interstates; the closest are far off in the Central Valley or Nevada. Plan your fill-and-dump around town, where Mammoth Mountain RV Park and the New Shady Rest dump station are located, before heading into the forest or up Tioga Pass, both of which offer no services. Because the area is high and remote, treat Mammoth as your supply base and roll out with full water and empty tanks.

Yes, absolutely. CA-120 over Tioga Pass climbs to nearly 10,000 feet and offers no RV services, and Yosemite's high country and valley campgrounds have no hookups either. Dump your tanks and fill fresh water in Mammoth Lakes first, then make the crossing with everything squared away. Remember that Tioga Pass closes for winter and often does not open until late spring, so confirm it is open before planning that route. If it is closed, you will backtrack down US-395, another reason to handle tank chores before you leave town.

The town of Mammoth Lakes has full services for a mountain resort community, including propane, a full-service grocery, and fuel, plus potable water at the developed forest campgrounds and private parks. Top off fresh water when you dump, since the dispersed forest sites and the high country offer none. Fill propane in town as well, because options thin out quickly once you leave along US-395. Treat Mammoth as your resupply hub for the surrounding Eastern Sierra, where towns and services are few and far between.

Summer and early fall are the sweet spot, roughly late May or June through September, when the campgrounds are open, the lakes are accessible, and dump stations are operating. Nights stay cold even in midsummer at this elevation, so pack layers. Fall brings gorgeous aspen color but campgrounds start closing by early to mid October. Winter is all about skiing, with most campgrounds and dump stations closed. For comfortable camping with reliable services, aim for the heart of summer through the early fall color.

Yes, the surrounding Inyo National Forest allows dispersed camping along US-395 and side roads, often with a permit and subject to seasonal and fire restrictions. These sites are free and scenic but completely without services, so you must arrive self-contained and pack out everything, then dump at a town or campground station afterward. It is a great budget strategy in the warm months, but do not expect any water or dump access in the forest. Always check current fire restrictions, which are often strict in the dry Eastern Sierra summers.

It is the best base in the region. From Mammoth you can reach the Mammoth Lakes Basin for fishing and paddling, ride the gondola or bike at Mammoth Mountain, visit Devils Postpile National Monument, and drive US-395 north to the June Lake Loop, Mono Lake's tufa towers, and the Bodie ghost town. With full services in town, including dumping and propane, it makes an ideal hub for exploring an area where most surrounding stops have nothing. Set up here, handle your chores, and day-trip out in the tow vehicle.

It is modest but rarely free. The dump station at New Shady Rest Campground charges a fee for use, and private parks like Mammoth Mountain RV Park include dumping with a full-hookup stay. Because the area is remote and seasonal, you will not find the kind of free public dumps that larger metros sometimes offer. Budget a small fee either way, and bundle dumping into a campground stay for the best value. The bigger cost factor is timing, since facilities only operate in season, so plan your dumps while everything is open.

Altitude does not change how you dump, but it affects your trip. At around 8,000 feet, expect cold nights even in summer, reduced engine and generator output, and stronger sun, so plan power and layers accordingly. The practical link to tank chores is that the cold can freeze hoses on shoulder-season nights, so drain and disconnect after dumping when temperatures drop. Otherwise, the main altitude effect on dumping is seasonal: the high elevation is why facilities close in winter, so handle your tanks while the season is open.

Yes, though they are limited by the mountain setting. Mammoth Mountain RV Park in town offers full hookups with water, sewer, and electric, plus a dump station, making it the go-to for travelers who want to manage tanks at their site rather than rely on the forest dump station. The forest campgrounds like New Shady Rest are dry camping only. If you want hookups, especially in shoulder seasons, book the private park ahead, since options are few and demand is high during the popular summer and ski periods.
