Gallatin Valley Earth Day Festival 2026

April 25 from 10am - 2pm
901 N Black Ave, Bozeman

MOSS Family Gatherings are casual, family-friendly opportunities to meet our instructors and staff, learn about upcoming programs, and connect with other families who love getting kids outside. Whether you’ve been long-time MOSS participants or are just starting to explore what we offer, we’d love to have you join us!

Each attendee will receive a free raffle ticket for a chance to win early registration to MOSS camps. Skip the stress of registration day and have your choice of themes and dates for summer 2026! Early registration is limited to one per family and two camps per child.

We're excited to see you at the Gallatin Valley Earth Day Festival! Stop by our table to:

Try hands-on activities — fun for the whole family and designed to spark curiosity in young naturalists
Score vintage MOSS gear — we'll have classic MOSS shirts available at bargain basement prices!

It's a great opportunity to meet our team, ask questions about summer camps, and celebrate the Earth together. We hope to see you there!
