Thorne’s unique brand of fun, hands-on learning in nature is not only for kids.  We have unique family programs too!  We hope to see you and your kids at one of our festivals.


Join Thorne at Sombrero Marsh on Boulder Valley School District’s In-Service Days for our FREE Spring and Fall Festival.  We will have nature themed arts and crafts, guided explorations of Sombrero Marsh with Thorne staff, and dancing and singing with our favorite nature musicians Jeff & Paige.  Thorne Festivals are most enjoyable for toddlers to tweens and their parent or guardian. All children must be accompanied by a guardian. 

Spring Fest 2023 is scheduled for April 21, 2023 and registration will open about a month before the event.

Sign up for our email list to be the first to know about our next festival and to receive registration information (space is limited and pre-registration is REQUIRED). 


Thorne is unable to run our Lil’ Explorers parent and child program at this time.

We look forward to running parent and child programs again at some point in the future. Please sign up for our email list to be notified when we resume these programs and receive other news about our early childhood programs.

Thank you for understanding!

Well, you’ve truly outdone yourselves this time! The concert was phenomenally educational while being fabulously fun!
