The climbing routes
Eldorado Canyon is one of the top US climbing destinations, with more than 500 routes on the canyon's sandstone walls, including the iconic Bastille Crack on the most-photographed formation.
Rattlesnake Gulch Trail
The signature day hike, climbing to the ruins of the old Crags Hotel and a Continental Divide overlook above the canyon.
South Boulder Creek and the canyon floor
The easy payoff: walk the creekside paths beneath the walls and watch climbers work the canyon's famous routes.
