This trail is heavily hiked on the weekends. With an average grade of 10% over loose soil, it's a lung busting climb. The trail climbs more gradually in the counter-clockwise direction. While the trail doesn't offer the most exciting trail features, it does offer some great views of Eldorado Canyon and the Continental Divide.It connects to another section of trail to make a lollipop.

Access Info

Rattlesnake Gulch is a short but steep lollipop located in Eldorado Canyon State Park. It is the only trail within the park open to mountain bikes. Because the connecting Fowler Trail from the Doudy Draw system is not open to bikes, riders must enter through the park gates and pay the $4/day park pass for riding in, or the $9 vehicle pass.

Note that parking fills up rapidly on the weekends.Please only park in legal spots in the Park or at other South Boulder trailheads like Doudy Draw or Marshall Mesa. There is no legal parking in town or at the pool.

Disclaimer

The upper loop of Rattlesnake Gulch has seasonal closures for wildlife. Check for more info: https://cpw.state.co.us/placestogo/parks/EldoradoCanyon
