Eldorado Canyon State Park sits just outside Boulder in the Front Range foothills. Its sandstone cliffs draw climbers from around the world, with more than 500 technical routes. Visitors can also hike a network of trails, picnic beside South Boulder Creek, and watch for many bird species. The park also has a visitor center and a bookstore with nature guides. Weekends and summer holidays from May through early October require a timed entry reservation for vehicles, and a shuttle from Boulder runs on some of those days.
