Every Tuesday, the Sombrero Marsh Environmental Education Center is free and open to the public from 2pm – 5pm for hands-on self-guided exploration. Come in, chat with an educator, and grab an exploration backpack full of activities and supplies. Then head on out to the marsh to identify tracks, listen to songbirds, and catch critters in a net! We have lots of exciting indoor exhibits too!


Stop by Sombrero Marsh Environmental Education Center in Boulder (1466 63rd St. Boulder, CO 80303) every Tuesday between 2pm – 5pm.  The Center has indoor and outdoor play/learning spaces including interactive exhibits, a trail system with boardwalks, and 45 acres of open space including both prairie and wetlands.  Whether you are an avid birder coming to view the ever changing species of birds at the Marsh or a mom looking for a fun, and free activity to do with your child, you will not be disappointed.  CLICK HERE for directions to the Marsh.  We are closed on holidays and every so often we close the facility for a special event, so be sure to check our event calendar before traveling to the Marsh.  For more information about visiting Sombrero Marsh, e-mail or call 303.499.3647 x100.

“My son caught a tiger salamander and the staff at Thorne helped him to identify what it was and why it lives here at the marsh. His reply was, “Mom, nature is COOL!”
