REI

Top choice in Denver


The flagship store of this outdoor-equipment super-supplier is an essential stop if you are heading to the mountains or just cruising through Confluence. In addition to top gear for camping, cycling, climbing and skiing, it has a rental department, maps and the Pinnacle, a 47ft-high indoor structure of simulated red sandstone for climbing and rappelling.

There’s also a desk of Colorado’s Outdoor Recreation Information Center, where you can get information on state and national parks, and an on-site Starbucks, in case you need some caffeine to accompany the adrenaline. There's even a play area on the top floor for the kids.
