Where can I take my dog off-leash in Aspen, CO?

Birdie and Goose have very strong opinions about where a leash is optional. Their top pick is Rio Grande Park, just north of Main Street — plenty of open grass, water fountains, and it backs right up to the river for a post-run cooldown. Locals also head to Wagner Park, right in the heart of downtown, which everyone just calls "the dog park" for a reason. For something a little wilder, Marolt Open Space on Castle Creek Road has a pond dogs are welcome to swim in — a favorite on hot summer days. One rule everywhere off-leash: your dog needs to stay in sight and actually listen when called. Bring extra poop bags, though Aspen keeps them stocked at most trailheads too.
