REI is a really cool shrine to all things outdoorsy. They have a waterfall outside, a trail for testing bikes, a climbing wall, and a giant fireplace inside. The selection is unparalleled from hiking boots to winter coats to avalanche survival kits. Prices can be on the higher side but nowhere else will you find such a huge selection. They even have a small hiking trail to test new boots on!
