Sombrero Marsh

Sombrero Marsh is a small Habitat Conservation Area with several short trails and a boardwalk that skirts the eastern shore for public use. This alkali marsh is rare to this area of the United States. Observe unique habitat and surrounding wildlife. Note that dogs are prohibited.

The Sombrero Marsh environmental education center is the result of a partnership between the Boulder Valley School District, Thorne Nature Experience and City of Boulder Open Space and Mountain Parks. It contains classrooms, viewing and assembly areas, and a laboratory for studying water and wetland soils. Thorne Nature Experience has developed science curricula to serve the district's schools. Students learn about the marsh outside along a network of trails and boardwalks that allow classes to visit the wildlife viewing blind and restored portion of the marsh. The western portion of the wetland is a wildlife sanctuary off-limits to the public.
