S. Downing St. & E. Louisiana Ave., Wash Park
Washington Park (known affectionately as Wash Park by Denverites) is one of those places that seems to be busy no matter when you visit. The 155-acre space centers on a lake, complete with a boathouse and swans, and surrounded by well-manicured gardens and plenty of green space where you'll find neighbors throwing the ball for their dogs or picnicking on warm summer nights. The entire park is encircled by a 2.5-mile dirt running path that's always packed with runners, parents with strollers, and power walkers, plus an inner, paved loop that's perfect for roller-bladers and cyclists. There are basketball courts, tennis courts, horseshoe pits, and grills on site.
