Marin County’s Best Summer Mountain Bike Camp for Kids

June 15th through August 7

Welcome to Ross Valley Mountain Bike Camp

Ross Valley Mountain Bike Camp, formerly known as “Otis Guy,” is widely recognized as one of the best mountain bike summer camps for kids in Marin County, CA. Based in Fairfax, in the heart of Marin’s legendary trail system, our camp is designed for kids ages 8–14 who are ready to build skills, confidence, and a lifelong love of riding.

At Ross Valley, we go beyond basic instruction. Our experienced coaches teach essential mountain biking techniques—balance, braking, climbing, descending, and trail awareness, while creating a supportive, fun, and confidence-building environment. Kids progress at their own pace, gaining not just riding ability, but independence and resilience.

Surrounded by the iconic trails of Marin County, campers experience the birthplace of mountain biking firsthand. Each day blends skill-building with adventure, helping kids connect with nature, overcome fears, and discover what they’re truly capable of.

If you’re searching for the best kids mountain bike camp in Marin County, Ross Valley Mountain Bike Camp delivers an unforgettable summer experience where fun, friendship, and fearless riding come together.

How Do I Determine if My Camper Is A Beginner Or Advanced Rider?

We have a large diversity of riders from ages 8-14 years old who come from all kinds of riding backgrounds, from beginners to advanced. We split into two groups for the week, beginner/intermediate and intermediate/advanced groups, to give each rider the best camp and Marin County mountain biking experience.

Beginners For those living locally, Shaver Grade, starting from Deer Park and riding up to 5 Corners provides a good indication for which group your child should be in. As rule thumb, if your child is stopping and dismounting multiple times on this climb, then the beginner group is great place to start! (As a point of reference for those traveling from outside the area, this climb is approximately 1.5 miles with a mixture of gradients and undulating surfaces)

Advanced would be those who can ride up Shaver Grade, with minimal stops or barely getting off their bikes would be best suited to the Advanced group.

If a rider proves to be better suited to either group, we can move them up or down a group after the first day.

Does My "Camper" Need To Be An Experienced Rider?

No - the only expectation is they can ride a bike safely. During the week we'll focus on core skills, team building and enjoying the outdoors on bikes. The primary focus is fun and building confidence, so they can get the very best from Marin County mountain biking

How Many Campers Per Counselor?

We have 1 counselor per 5 campers, with additional counselors in training (CIT) to provide extra supervision and support.

Are All Counselors Trained In First Aid & CPR?

Yes, all counselors are First Aid & CPR certified.

Are Scholarships Available?
