Home of our one-of-a-kind Arkansas River Outpost. All Browns Canyon and Numbers trips will depart from this location. If you are looking for a little caffeine fix before your trip, or a smoothie, ice cream bar, or espresso, after your trip, swing by Canyon Door Coffee located at the Outpost. We also serve a great selection of breakfast burritos if you are looking for a little extra paddling power! The Arkansas River Outpost is located at mile marker 208 on US HWY 24. We are an hour south of Copper Mountian and Frisco, and just over an hour from other Summit County areas.
