The dirty knees will say it all - our Watershed Warriors program truly allows your child the chance to connect with nature.

4 DAY CAMP CHOICES
THE EXPERIENCE Camp
DOG DAYS OF SUMMER Camp
RIDE FIVE Beach Camp
ROCK FIVE Outdoor Rock Climbing Camp

THE EXPERIENCE CAMP, back by popular demand, is a 5 day sampler of exciting beach fun, including boogie boarding, surfing, games, tidepooling, outdoor rock climbing at one of the Bay Area’s most beautiful crags, hiking, birdwatching, hiking, birdwatching, nature journaling, games and exploration. We’ll also explore karate at the the Martial Arts Academy of Marin with Sensei Will and incorporate mindfulness, brief meditative moments and yoga to help us stretch and get ready to climb the rocks or get in the water. We provide van transportation to all locations.

DOG DAYS CAMP partners with Marin County’s finest dog trainers, and meets with local dog rescuers, Golden Gate Parks Conservancy staff and others, to get out on the trails and find out what's involved in choosing the right trails for a hike with your dog, how to walk dogs, and all of the etiquette involved with sharing the trails with wildlife and other people and their pets. Our goal is to keep the trails open for our furry friends by creating good stewards of the land and responsible dog owners.

Campers don’t need to have or bring their own dog. We share all of the campers’ dogs at camp, so all campers will have a chance to walk one or more dogs every day. Camper families apply for their dogs to attend through a screening process developed by our dog training expert. Once the dog has been approved, campers can bring their own dog to camp at least one day per week.

In the past we’ve worked with trainers Michelle Stern, Ally Stoops, Tricia Breen, Trish King, Rebecca Bradford, and Kathleen Burke.
 
We’ll also begin to understand the natural history of the coyotes that are our neighbors through meeting with wildlife experts, how to coexist peacefully with them and tips for keeping our furry friends safe from these majestic creatures who are helping to keep rats at bay. We’ll do some litter clean ups along the way. No van transportation this week, we will meet in convenient locations in or near Mill Valley.

Many families use this camp as a way to figure out whether their kids and family are “dog ready!”

RIDE FIVE CAMP is exciting beach fun including five days of boogie boarding, surfing, games, tidepooling, marine biology activities, service learning opportunities, and more at Muir Beach, Stinson Beach, and/or other Marin beaches, conditions permitting.
