“Experience a twenty-mile excursion exploring the volcanic remnants that helped to shape the San Juan Mountains.”— Caroline Cordsen
Second only to Pikes Peak, Wheeler was once a highly trafficked tourist destination back in the 1800s when it held the designation of Colorado’s first national monument. But having long since been stripped of its title, now the journey out is just as laborious as its illustrious history.
Use care heading up to Halfmoon Pass during summer afternoons, and be weary of incoming thunderstorms.
When snow-free, an ATV or modified high-clearance vehicle is recommended on the 4X4 road leading into Wheeler.
