Chautauqua Park
Head to this gorgeous park at the base of the Flatiron Mountains to tromp more than 40 miles of scenic hiking trails and get a little closer to those dramatic rock formations. The grounds are also home to an auditorium that hosts the Colorado Music Festival, which features international artists over six weeks in July and August.
Media Archaeology Lab
Located on the University of Boulder campus, this unique collection of historical devices includes phonograph players, Commodore 64 computers, and other relics of technology’s past. They all work, and visitors are encouraged to get hands-on with the collection. Visits are by appointment only.
Go Tubing
Few activities embody the pace of summer more than lazily bobbing along, toes in the water, sun on your face, and your bum in a tube. You can launch a tubing trip on Boulder Creek where it curves through Eben G. Fine Park, just a short walk from the town’s commercial center, and spend the day floating along. Tubing season is roughly May through June. You can buy or rent tubes in town, as well as schedule a pickup once you’re ready to dry off.
