Planning your ride
The bike park typically runs from mid-June through Labor Day, weather depending.

It’s the most family-friendly way to try lift-served riding in the county. Prefer to hike? See hiking in Keystone.
Before you go
Colorado afternoons build thunderstorms fast, so start early and be off high, exposed terrain by early afternoon. Ride within your limits at altitude, yield to hikers and uphill traffic, and pack the essentials — water, layers, tube/pump, and snacks. New to the elevation? Read up on the altitude first, and see the full Colorado mountain biking guide, and gear up with our mountain bike gear guide.
