What’s better than sticking your feet in a cool creek or lake on a warm day while taking in sweeping mountain views? Not much, if you ask us. In Boulder, there are refreshing water activities around every corner. Tube down Boulder Creek (which runs right through downtown), paddle the sunny Boulder Reservoir, feel the mist off Boulder Falls, or go birdwatching at Walden Ponds. You’ll be refreshed by the water, wildlife and panoramas.
