Family Visits


Do you love to explore nature with the children in your life? Thorne welcomes you and your little ones to the Sombrero Marsh Environmental Education Center for a fun, hands-on, self-guided nature experience. From 1-5 PM on Mondays and Tuesdays (excluding holidays), you can come in, chat with an educator, grab an exploration backpack full of dip-nets, insect trays, field guides, and a map of the facility. From there, you can head out to the marsh to identify grasses, listen to songbirds, and catch creepy-crawlies in a net. There are even indoor exhibits with nature specimens and a nature library to explore! There is no charge to visit Sombrero Marsh or to explore the indoor exhibits and reservations are not required. For more information about Thorne’s Family Visits, e-mail or call 303.499.3647.

Sombrero Marsh is owned and managed by the City of Boulder Open Space and Mountain Parks, and you are welcome to explore it whenever you like.  OSMP only asks that people stay on the trails and leave only footprints.

If you are a large group or you would like to schedule a guided field trip with our amazing educators, we would love to discuss the options with you.
