Whatever part of their paychecks outdoor-loving Denverites still have left after paying for their lift tickets and filling up their Outbacks with gas usually ends up getting spent on Platte Street, where three of Denver's biggest outdoors stores are clustered next to each other. Located in the old Denver Tramway Company building, retail giant REI's flagship store (1416 Platte St., 303-756-3100) is a multi-story emporium of everything from sleeping bags to bikes to GPS units, with meeting rooms for classes on the upper level, a climbing wall, and an in-store Starbucks whose deck looks out over the Platte. Across the street, Wilderness Exchange United (2401 15th St., 303-964-0708) is one of Denver's best spots for new and used climbing gear, skis and apparel. And from its base in the bottom level of the Natural Grocers building, Confluence Kayaks (2373 15th St., 303-433-3676) sells boats and teaches paddling skills in an in-store pool and nearby Confluence Park.
