BECAUSE THEY'RE THERE
Some indoor rock-climbing gyms cater to children celebrating birthday parties or company team-building retreats. Gyms for serious climbers can be much more exciting. Even the ones with the toughest routes have beginner-friendly areas and rent out harnesses, shoes, chalk, and belay devices. (First-time visitors should expect to sign a waiver.)
Climbing gyms typically have top-rope climbing and bouldering areas, as well as private rooms for instructor-led classes. Visitors are also likely to find a fitness room, locker rooms, showers, and a steam room or sauna. The 10 climbing gyms on this list go beyond the usual amenities, offering features such as 24-hour access or 25-foot bouldering routes that overhang foam pits and attract top climbers. Many are reasonably priced for visitors looking for something memorable, healthful, and challenging to do: $15 to $30 for a day pass with rentals.
