20th Street Recreation Center

The 20th Street Recreation Center, a city facility in the heart of downtown Denver, may not have the newest and fanciest equipment, but it has character and history that would give any other gym a real workout. Originally a boxing gym, it has an old-school feel, few crowds and helpful staffers and regulars alike. And the Denver Parks and Recreation pass comes with the right price: For less than $200 a year, you have access to an array of recreation centers throughout the city.
