A Week of Fun, a Lifetime of Memories

Our Sleep Away Camps begin on Sundays and pack a schedule full of fun until pickup on Friday. All Sleep Away Camps stay at Camp High Sierra and use the historic recreational lodge and campground as their basecamp as they embark on adventures in the Eastern Sierra.

During the week, all campers have fun with traditional camp games and team building activities, and have opportunities to bike, ride horses, climb, paddle board, swim, hike, play at the Adventure Center, and ride the Scenic Gondola to the Eleven53 Interpretive Center.  

At night, campers stay in our canvas tent cabins at Camp High Sierra and get to cook around campfires, stargaze, night hike, play games, and roast s'mores, all while hanging out and building awesome friendships that will last a lifetime. 

Camp Options

Camp Options

Choose one of three camp options that interest your camper most – whether they want to the excitement of ripping trails on a mountain bike, taking in the scenic beauty on horseback, or would like a bit of everything, we have great options for all styles.

  • Adventure Camp
  • Mountain Bike Camp
  • Horseback Camp

Adventure Camp

For campers who want a bit of everything, our Adventure Camp offers it all. Beginners and experienced athletes alike will enjoy a full range of camp and mountain activities in the majestic Eastern Sierra. 

Mountain Bike Camp

With a focus on big fun, all skill levels will boost their mountain biking chops – we've even taught many campers how to ride bikes. Campers will bike every day, learning to ride, and rip, at the premier mountain bike park in the country with friends and trained counselors. 

Groups are assigned based on skill level, where everyone has a chance to master the right skills at the right pace, while maximizing fun.  

Horseback Camp

Explore the Eastern Sierra the same way settlers did – on horseback. Learn to ride or improve the skills you already have. Campers will take a horsemanship course at one of our local pack outfitters, and will put their knowledge into action on several iconic trail rides in the area. 

Campers will spend most of their active time at the pack station or on the trail with new friends, counselors, and trained wranglers

Summer Camp FAQs

What will my camper be doing?

Your camper will be participating in different adventure activities and traditional camp games, based on the camp program for which you enroll. Mostly, we will be mountain biking, hiking, paddle boarding, horseback riding, and playing at the Adventure Center at Mammoth Mountain. Please email for more details. 

Do you provide gear and equipment for my camper?

We will provide the necessary gear for the camp activities that we will be doing. You will be responsible for packing all personal items. Please see our packing list for more details. 

What do I need to bring?

For a list of items to bring to camp (and what you should leave at home), please see our packing lists. 

What is the difference between the Week-Long Sleep Away Camp and the Week-Long Day Camp?

Residential camp is an overnight camp experience from Sunday–Friday. The Week-Long Day Camp is a daily drop-off program from 9AM–4PM Monday–Friday.

Can I bring my own mountain bike?

We provide mountain bike rentals and safety gear for our campers. If you would like to bring your own mountain bike or gear, you are welcome to do so. We do require that all campers wear a full face helmet, and knee and elbow pads.

Where will my camper be sleeping during overnight camps?

Campers stay at Camp High Sierra in our private summer camp tent site. We sleep in spacious canvas, walled tents that fit up to 10 comfortably. 

Can I call my camper during the week?

You are welcome to speak with your child during the week, however, we generally advise against this as it usually causes homesickness that can have an overall detrimental effect on your camper's week with us. 

Can my camper bring a cell phone?

We allow cell phones for photographic uses only. All cell phones must be on airplane mode and may not be used for anything other than photo and video purposes. We confiscate cell phones being used inappropriately for safety reasons. Please contact for more information. 

Will my camper be able to sleep in the same tent as their friend or sibling?

We try to accommodate friends and family as much as possible. Just let us know as early as you can so we can make necessary arrangements.

My camper has never spent the night away before. What do I need to know?

Often times your camper spending their first night away from home is more difficult for the parents than it is for your camper. We have a highly trained camp staff that excels at making your camper feel comfortable and welcome at camp. 

We are committed to providing your camper with a safe, fun, and educational week. Please read over our webpage for an overview of of the program, and please do not hesitate to reach out to camp director Doug Gebhart with any further questions or concerns. 

Can I bring a friend?

Yes, of course! We offer a 10% referral discount to friends and siblings. If you bring 5, your camp stay is FREE. 

My camper has medical needs and/or dietary restrictions. Do you make accommodations for special needs?

Yes – for medications, our health staff member will keep the medicine in a secure, locked location and administer it when needed. Please send your camper with enough supply for the duration of camp.

Our camp cook can accommodate most dietary restrictions. Please contact us early to discuss and we can plan meals for your camper.  

What meals can my camper expect?

We will provide all meals during your camper's scheduled stay. Most meals are served by our camp cook, who prepares wholesome meals consisting of a protein, vegetable, and a carbohydrate. A typical day may include pancakes, fruit, and bacon for breakfast; a hamburger, fries, and salad for lunch; and tacos for dinner. 

Meals not served by our camp cook will be served at one of our mountain dining venues: Broadway Marketplace, The Lunchbox, or Yodler Restaurant. 

Who will be watching my camper?

Mammoth Summer Camp is directed by the same team that runs Mammoth's Ski & Snowboard School – one of the most successful youth programs in the country. Mentoring young people, coaching athletes of all abilities, and introducing beginners to the exhilaration of mountain activities is what our staff does every day of the year. Depending on the activity, we have 4:1 to 6:1 camper/staff ratio during the day, and 8:1 at night. 

Where will my camper be and how will they get there?

Our daytime camp activities take place all over the Eastern Sierra. We will mostly be at Camp High Sierra or in the Mammoth Lakes vicinity. Campers are transported to their activities via our camp van or camp SUV (with a fully and appropriately licensed driver), town trolley, bus, or by walking or biking. 

Does my camper need to bring money?

We do offer opportunities for your camper to buy snacks or souvenirs. We usually find that $20 is plenty. We are not responsible for lost money. 

Please contact Camp Director Doug Gebhart at for further information and with all other inquiries.
