The Rockies do not have to drain your bank account. Skip the resort crowds and summer still serves up free hikes, cheap campsites, and rooms that leave your wallet mostly intact. The national parks charge one flat weekly fee, and many of the best trails cost nothing at all. Sleep at a mountain YMCA for around a hundred dollars or catch a nightly rodeo in Cody. These twelve spots prove a Rocky Mountain vacation can run lean without feeling cheap.
