37.6486° N, 118.9721° W
Quick Overview
Mammoth Lakes sits at about 7,880 feet on the eastern side of the Sierra Nevada, and it may be the best public-land RV base in California. The camping here leans heavily public: the Inyo National Forest runs a dense cluster of Forest Service campgrounds right in and around town, from the walkable Shady Rest sites to lakeside spots up in the Mammoth Lakes Basin. If you want to plug in, a few private full-hookup parks fill that gap, so you get to pick your trade-off: alpine setting and quiet, or 50-amp power and a hot shower at the end of the day.
On the public side, New Shady Rest and Old Shady Rest Campgrounds put you in a Jeffrey pine forest within walking distance of town, both dry camping with no hookups. Up Lake Mary Road, Lake Mary Campground and Twin Lakes Campground sit right on the water in the Lakes Basin, prime for trout fishing and paddling, though the sites tighten up and some cap out around 36 feet. All of them book through Recreation.gov on a rolling six-month window, and the good summer weekends go within minutes of release.
For hookups and big rigs, Mammoth Mountain RV Park sits right at the town entrance on Highway 203 with full 30 and 50 amp water and sewer sites, pull-throughs, an indoor pool, and an on-site dump station. A little south toward Crowley Lake, Paradise Shores RV Park offers full hookups at around 7,000 feet. Between the two you can run a 40-foot coach without sweating length limits, which is harder to promise at the Forest Service sites where the rigs and the roads both get smaller.
The short version: come for the scenery and the fishing, book your public sites the morning the reservation window opens, and keep a private park in your back pocket for the nights you need power and a dump. Below we cover getting here, what it costs, when to come, and the questions we hear most from RVers planning a Mammoth trip.

Almost everyone reaches Mammoth Lakes on US-395, the main north-south highway down the eastern Sierra, and it handles any rig without drama. From the highway you turn west onto CA-203, which becomes Main Street and carries you into town and toward the RV parks. Coming from the south, Los Angeles is about five hours away; from the north, Reno runs roughly three hours. Mammoth Yosemite Airport sits right in town if you are flying in to pick up a rental rig or meet friends.
Two cautions for bigger coaches. The stretch of CA-203 past town climbing to Minaret Summit is steep and narrow, and it is not the place for a 40-footer, so leave that drive toward Devils Postpile to your tow vehicle. And Tioga Pass on CA-120 over to Yosemite carries length limits and closes seasonally with snow, often well into June, so do not count on it as your way in during spring. Make US-395 your spine and you will have no trouble getting the rig to camp.

Before You Go: RV Trip Essentials
Dump stations are only one piece of the trip puzzle. Before you set out for your trip to Mammoth Lakes, California, it's worth taking thirty minutes to check that the basics are in place — the four areas below are where unprepared RVers most often get stung.
Check your RV insurance coverage
A standard auto policy rarely covers a Class A, Class C, or travel trailer the way a dedicated RV insurance policy does. If you're financing a motorhome, lenders typically require comprehensive and collision; full-timers should additionally price in vacation liability and personal belongings coverage. Rates vary widely by state and travel pattern — compare quotes from multiple RV-focused carriers before each season.
Know your roadside assistance options
RV-specific roadside plans tow motorhomes and trailers that regular AAA coverage won't touch — flat beds, mobile mechanics, tire service for duallies, and even emergency lockouts at remote campgrounds. Good plans cover your spouse and trailer even if you're driving a separate vehicle, and some include trip interruption reimbursement if a breakdown costs you a reservation.
Decide about an extended warranty early
Original manufacturer warranties on new RVs typically run 12–24 months — shorter than most buyers realize. An extended service contract (essentially a mechanical breakdown policy) covers the appliances, slides, levelling systems, and drivetrain components that can run $3,000–$10,000 to replace. The time to price one is before the factory coverage expires, not after something breaks.
Set up a travel rewards card for fuel and fees
A no-annual-fee travel or gas rewards card pays for itself on a single month of RV travel. Expect to spend $400–$800 per week combined on fuel, campgrounds, and propane — 3–5% cash back on gas alone covers the next oil change. For bigger trips, a sign-up bonus can offset campground fees for the whole season.

Dump Station Costs in Mammoth Lakes
Camping here splits cleanly by type. The Inyo National Forest campgrounds are the value play, generally in the low-cost band of roughly the mid-$20s to low-$30s per night for a dry site with no hookups, plus a small Recreation.gov reservation fee. You supply your own power and water, so budget for propane and a full fresh tank.
The private full-hookup parks in and near town sit higher, commonly in the $60 to $90 range during peak summer and ski season, reflecting the 50-amp power, sewer, and amenities. If your budget is tight, the math favors a dry-camping stretch in the forest with a night or two at a private park to dump, refill, and recharge. Shoulder season in fall usually brings the best value, with softer demand right before the snow closes the public sites for winter.

Best Time to Visit Mammoth Lakes by RV
Winter
Nov - Feb
15°F - 40°F
Crowds: Low
Most public campgrounds are closed under deep Sierra snow. Mammoth Mountain RV Park stays open with limited services for ski-season RVers, so plan for winterized full-hookup camping only.
Spring
Mar - May
26°F - 52°F
Crowds: Low
Snow lingers late up here. Most Forest Service campgrounds do not open until late May or June, and a heavy snowpack can push openings further into summer, so confirm before you tow up.
Summer
Jun - Aug
40°F - 78°F
Crowds: High
Prime season. Book Recreation.gov sites months ahead, especially holiday weekends, and expect afternoon thunderstorms plus genuinely cool nights at elevation even in July.
Fall
Sep - Oct
30°F - 60°F
Crowds: Medium
Best value and best color. Many Forest Service campgrounds close between late September and mid-October as nights drop below freezing, so lock in your dates early.
Explore the Mammoth Lakes Area
Book early and book smart. Set a Recreation.gov reminder and reserve your Inyo National Forest sites the morning the six-month window opens for your dates; that is how the best summer weekends get claimed. If you strike out, a handful of Forest Service and higher-elevation sites stay first-come, so roll in early on a weekday for the best shot rather than gambling on a Friday afternoon.
Respect the elevation. At nearly 7,900 feet the town is high enough that you should ease into it, hydrate hard the first day, and expect cool nights even in July when the daytime shirt gives way to a jacket after dark. If you need full hookups, the in-town private parks are your play, because the Forest Service campgrounds are dry camping only, so top off water and charge your batteries before you leave pavement. For Devils Postpile in summer, plan around the mandatory shuttle, since RVs are restricted on Minaret Road during shuttle hours; park the rig in town and ride in for the day.

Frequently Asked Questions About Dump Stations in Mammoth Lakes
What are the best RV parks and campgrounds in Mammoth Lakes?
It depends on what you want. For full hookups and big-rig access, Mammoth Mountain RV Park at the town entrance is the go-to, with an on-site dump station and an indoor pool, and Paradise Shores RV Park sits south toward Crowley Lake. For scenery and value, the Inyo National Forest runs New Shady Rest and Old Shady Rest within walking distance of town, plus Lake Mary and Twin Lakes Campgrounds right on the water in the Lakes Basin. Those public sites are dry camping, so choose power or setting.
Do Mammoth Lakes campgrounds have full hookups?
Some do, most do not. The full-hookup camping is at the private parks: Mammoth Mountain RV Park offers 30 and 50 amp electric with water and sewer and pull-through sites, and Paradise Shores near Crowley Lake also runs full hookups. Every Forest Service campground in the area, including the Shady Rest sites and the Lakes Basin campgrounds, is dry camping with no hookups, though several have a shared dump station and potable water. If you need to plug in, book a private park; if you can run off your batteries and tanks, the forest is beautiful.
How much does RV camping cost in Mammoth Lakes?
The Inyo National Forest campgrounds are the value option, generally landing in the mid-$20s to low-$30s per night for a dry site, plus a small Recreation.gov reservation fee. The private full-hookup parks run higher, commonly in the $60 to $90 range during peak summer and ski season, which reflects the 50-amp power, sewer, and amenities. A common play is to spend most nights dry camping in the forest and drop into a private park for a night to dump, refill water, and recharge. Fall shoulder season usually brings the softest prices.
How far ahead do I need to reserve a campsite in Mammoth Lakes?
For summer and holiday weekends, months ahead. The Inyo National Forest sites release on Recreation.gov on a rolling six-month window, and the popular Lakes Basin and Shady Rest sites can be gone within minutes of opening for peak dates. The trick is to set a reminder and book the morning your six-month mark hits. Private parks also fill early for summer and ski-season weekends, so reserve those direct as soon as your plans firm up. Midweek and shoulder-season trips are far more forgiving and often bookable close to your dates.
When is the best time to go RV camping in Mammoth Lakes?
Summer, roughly July through September, is peak for a reason: the campgrounds are open, the lakes are thawed, and the high country is accessible. It is also the busiest and priciest window. Fall, from mid-September into October, is our favorite for value and color, though public campgrounds start closing as nights freeze. Spring is unpredictable because snow lingers and many sites do not open until late May or June. Winter camping is limited to Mammoth Mountain RV Park for ski-season RVers, since the public forest sites are buried in snow.
Can big rigs (35 to 40 ft) camp in Mammoth Lakes?
Yes, but choose your site carefully. US-395 and CA-203 into town handle any size rig, and the private parks are built for larger coaches: Mammoth Mountain RV Park has pull-through and back-in big-rig sites, and Paradise Shores takes 40-footers. The Forest Service campgrounds tilt smaller and more rustic; Lake Mary, for example, fits RVs up to about 36 feet, and the Lakes Basin sites can be tight. If you are running a 40-foot coach, the in-town private parks are the safer bet. Always check posted length limits before you commit to a mountain loop.
Are there free or first-come camping options near Mammoth Lakes?
A few. While the marquee Inyo National Forest campgrounds are reservable on Recreation.gov, a handful of Forest Service sites and some higher-elevation campgrounds stay first-come, first-served. Your best shot is to arrive early on a weekday rather than a weekend. There are also dispersed and dry-camping options on national forest land in the broader eastern Sierra, though rules and closures vary by area and fire season, so check current conditions with the Inyo National Forest before you rely on boondocking. During peak summer, do not assume a first-come site will be open on a Friday afternoon.
What is the elevation in Mammoth Lakes and does it affect camping?
The town sits at roughly 7,880 feet, and the campgrounds in the Lakes Basin climb higher still. That altitude matters. Give yourself a day to acclimate, drink more water than feels necessary, and go easy on the first hike. Nights stay cool even in midsummer, so pack layers and expect to run your furnace some mornings. The elevation also drives the short season: snow closes most public sites from late fall through spring. Engines and generators lose a little power up here too, which is normal and nothing to worry about.
Can I camp right on the lakes in the Mammoth Lakes Basin?
Yes. Lake Mary Campground and Twin Lakes Campground both sit lakeside in the Mammoth Lakes Basin up Lake Mary Road, and they are prime for trout fishing and paddling straight from camp. Both are Inyo National Forest sites, so they are dry camping with no hookups, and they typically open from late May or June through mid-September depending on snow. Sites are more compact than the in-town options, and some cap around 36 feet, so bigger rigs should confirm length limits. Reserve through Recreation.gov early, because these waterfront sites are among the first to go.
How do I get to Mammoth Lakes with an RV?
The spine is US-395, the main highway down the eastern Sierra, which handles any rig comfortably. From US-395 you turn west onto CA-203, which becomes Main Street and leads into town and to the RV parks. From Los Angeles it is about a five-hour drive; from Reno, roughly three. Avoid using Tioga Pass (CA-120) from Yosemite as your route in spring, since it has length limits and opens late after snow. And save the steep, narrow climb over Minaret Summit past town for your tow vehicle, not the coach.
Is there a dump station in Mammoth Lakes?
Yes. Mammoth Mountain RV Park has an on-site dump station, and several of the Inyo National Forest campgrounds, including the Shady Rest sites, offer a shared dump station and potable water even though the individual sites are dry camping. If you are dry camping in the forest, plan a stop to empty tanks and refill fresh water before you head down the highway. For the full rundown of where to empty your tanks in the area, see our guide to RV dump stations in Mammoth Lakes, which covers the public and private options in more detail.
Can I visit Devils Postpile National Monument with my RV?
You can visit, but not by driving your RV in during peak summer. When the shuttle is operating, private vehicles including RVs are restricted on Minaret Road during shuttle hours, so you park at the Mammoth Mountain Adventure Center and ride the mandatory shuttle down to Reds Meadow, Devils Postpile, and Rainbow Falls. This is a good thing for RVers, because that road is steep and narrow and no place for a big rig. Set up camp in town, leave the coach on its site, and take the shuttle for the day.
What is there to do around Mammoth Lakes while camping?
Plenty, and it is why people come. Trout fishing is the headline, with more than 400 lakes and streams in reach, plus hiking and backpacking straight from the Lakes Basin, mountain biking at the Mammoth Bike Park, and scenic drives like the June Lake Loop and US-395 itself. Day trips reach Devils Postpile and Rainbow Falls by shuttle, the tufa towers at Mono Lake, and the ghost town at Bodie State Historic Park, both a half hour or so north. In winter the town shifts to skiing and snowmobiling. Fall color along the eastern Sierra is outstanding.
