Accessible Sombrero Marsh - Boulder County
Ownership: None Listed
Description: You never know what you are going to find at Sombrero Marsh. You might find a dusty clearing where Sombrero Pond used to be, or you might find a Garganey--both have occurred here. When water levels are right, this can be impressive shorebirding, and the marshes can be bustling with rails.

Habitat: Pond/Lake/Reservoir
Directions: From Denver, take US 36 to Boulder, exiting onto Foothills Parkway north (note: this is a tricky double exit; take the right off of US 36 and then an immediate left to stay on Foothills). Follow Foothills Parkway (CO 157) north to Arapahoe, then turn right (east). Head east to the intersection with 63rd Street (stoplight) and turn right onto the Sombrero Marsh entrance road.
