Discover the Guided Discoveries Difference
What makes Guided Discoveries different is our approach: every program is built on a foundation of experiential learning, personal growth, and belonging. As a nonprofit, we reinvest in our mission—to make a difference in the lives of children through unique opportunities for discovery.
Each camp is designed to inspire confidence and curiosity through real-world adventure, whether that’s exploring Catalina’s kelp forests, climbing Idyllwild’s granite peaks, or creating in a professional teaching kitchen. Across every program, our focus stays the same: helping kids discover who they are and what they’re capable of.
Our California Overnight Camps
From ocean waves to mountain trails to creative kitchens, Guided Discoveries offers three distinct overnight camps that capture the best of California. Each program combines traditional summer camp fun with hands-on learning and supportive community, helping kids and teens discover new skills, confidence, and lifelong friendships.
Why Overnight Camp Matters
Overnight camp is more than just a summer getaway—it’s a life-changing experience that builds independence, confidence, and resilience. Away from screens and daily routines, campers discover their strengths, form meaningful friendships, and learn to thrive in a supportive community. Guided Discoveries programs give every child the space to explore, take healthy risks, and develop a sense of belonging that lasts long after summer ends.

Every child is unique—and finding the right overnight camp can make all the difference. Whether your camper dreams of exploring the ocean, building rockets in the mountains, or mastering new recipes in the kitchen, Guided Discoveries offers experiences that match every interest and comfort level. Our directors and enrollment team are here to help families choose the best fit through personal conversations, resources, and our easy Camp Match Quiz, so you can feel confident knowing your child will thrive.
