Inyo/Twin Lakes

Overview

Twin Lakes Campground provides a serene mountain retreat within the Inyo National Forest. Located at an elevation of approximately 8,600 feet, this destination serves as a premier gateway to the spectacular Mammoth Lakes Basin. It offers a traditional camping experience where the focus is on the breathtaking natural landscape of the Eastern Sierra. The atmosphere is quiet and rustic, allowing travelers to truly immerse themselves in the high-altitude environment while enjoying a sense of secluded mountain living.

Location & Surroundings

Situated just south of the town of Mammoth Lakes, the park is surrounded by towering lodgepole pines and sits along the shores of the Twin Lakes. The craggy peaks of the Sierra Nevada mountains provide a dramatic backdrop for every campsite. The area is defined by its crisp mountain air and the soothing sounds of Mammoth Creek flowing nearby, creating a peaceful sanctuary. Visitors are treated to stunning views of Mammoth Mountain and the surrounding granite ridges that dominate the skyline.

Amenities & Park Features

This is a classic forest service-style park where the amenities prioritize functionality in a wild setting. While the park is primarily geared toward dry camping, it provides essential features to ensure a comfortable stay:

  • Heavy-duty bear lockers are provided at each site for mandatory food storage.
  • Spacious sites include individual picnic tables and fire rings for evening gatherings.
  • The grounds offer access to potable drinking water and well-maintained flush toilets.
  • The nearby Twin Lakes Store provides basic supplies, firewood, and boat rentals.

Nearby Attractions & Things to Do

Outdoor enthusiasts will find no shortage of activities just steps from their RV. Fishing for rainbow trout is a primary draw, with easy access to the lakes and nearby streams. Hikers can explore the Dragon's Back Trail or take a short drive to the iconic Devils Postpile National Monument. The nearby town of Mammoth Lakes offers a convenient shuttle system, making it easy to visit local breweries, restaurants, and the Mammoth Mountain Adventure Center for world-class mountain biking.

Who This Park Is Best For

Twin Lakes is ideal for RVers who prefer a rustic, off-grid experience over the amenities of a commercial resort. It is a perfect choice for fishing enthusiasts, nature photographers, and families who enjoy traditional outdoor activities like campfire cooking and stargazing. Those seeking a scenic alpine basecamp for exploring the rugged high-country wilderness of California will find this park to be a rewarding and tranquil destination.

The campsites were well maintained with very level parking areas. The bathrooms were clean and well kept. Even though the campground was full, it was still reasonably quiet and peaceful. I would absolutely camp here again!

Excellent campground by a cute lake. Very clean, perfect location for relaxation and day hikes, peaceful, shaded. I couldn't recommend it enough.

The hardest working camp hosts (Mike?) I have met. Always clean bathrooms even when the camp was full. The location is hard to beat with the proximity to Mammoth yet tucked away at Twin Lakes. Just please be a respectful visitor and store your food properly in the provided bear boxes. Bears live here and this is their home. Respect them.

Despite the rain, thunder, lighting and hail we had such a great time. The camp sites are so well taken care of. We have been camping all over in many states and by far the best and cleanest bathrooms. The camp hosts Ralph and Virgina are so helpful and nice. We needed a fire starter for the camp fire and they gave us their own personal. Super kid friendly there were plenty of kids our kids made friends with. Definitely coming back. Mammoth is one of our favorite places but the cleanliness, great camp hosts and not too many bugs were great. We went end of August. Adventure Awaits!

What a great campground. Peaceful, quiet and just enough. Bike paths are great and mtn bike trails easily accessible. Hiking paths if you choose. Check in a breeze with wonderful "southern" hospitality from the camp hosts. Dog friendly and wonderful folks to talk with while you're strolling along. We had sun for solar and never needed the generator. Though not all spots are sunny. We saw a deer in our campsight arriving late. So nice to see. The next day as we were going out we saw a small bear cub near tamarak bike kayak rentals. The staff was chasing him away. Lots of posting for the bears btw. Sad, the tamale lady has retired from the general store. We already planning our return.
