Nearly half of Boulder County is public land, so there are literally hundreds of trails available to birdwatchers, from the plains to the Continental Divide. Here are a few of our favorite local and regional birdwatching destinations.

For a comprehensive list of wheelchair-accessible trails, visit Trails Accessibility Guide. For finding trails, we recommend the Boulder Open Space and Mountain Parks trail map (available online or at their offices at Chautauqua Park and 2520 55th Street).
