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 or Lil’ Explorers Parent and Child programs.


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.

Festivals activities are mostly held outdoors, rain or shine.  Please plan for the weather and bring sunscreen, appropriate clothes, and water.  You are also welcome to bring a picnic lunch and blanket to sit on and enjoy the mountain views.  

Fall Fest 2022 on October 17th is full, but you can CLICK HERE to sign up for the waitlist.

Due to the ever-changing circumstances related to COVID, Thorne is not running Lil’ Explorers at this time. Thank you for understanding.

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