The Town’s Rhyolite Bike Park, 1701 Crystal Valley Parkway, currently includes a beginner downhill flow line , an intermediate downhill flow line, an advanced jump line, a return uphill trail and an entry level pump track. In 2012, a permanent cyclocross course was added to the outskirts of the park, which is used for practice throughout the year and for races in the fall.

In May 2013, a session zone was added with beginner, intermediate and advanced lines.

The site has been adopted by Castle Rock Bike and Ski through the POST Partners volunteer program and helps lead a group called the Dirt Crew, who helps maintain and improve the bike park. If interested in joining the group please contact Mark Neel at or call 303-688-1722 or the POST Partners coordinator at 303-814-7456 or
