About

Climbing at The Gravity Vault Radnor

The Gravity Vault's Philadelphia-area gym sits on King of Prussia Road in Radnor. It held its grand opening in March 2017 as the chain's third franchise-run gym and has around 16,000 square feet of climbing.

Ropes dominate: there are more than 100 rope stations, 78 of them top ropes, plus a lead cave and other lead-only areas, two cracks, a chimney, a rappel tower and auto belays. The bouldering area includes a MoonBoard, and off the walls there's a fitness room with cardio machines and weights, locker rooms with showers, a party room and a shop.

Getting started

Newcomers can book a one-hour staff-belayed session for up to four climbers aged five and over, drop in for two instructor-belayed climbs, or come as a group of five or more for a 90-minute introduction. Climbers aged 14 and over who already belay with a Petzl GriGri can take a free belay test; everyone else can join the top-rope belay class, cheapest on Monday and Friday evenings. Lead climbers must be 16 or over and pass a lead test, or take the lead class.

Classes and community

Kids' classes for ages 5 to 13, break and summer camps (Camp Rocks includes two off-site trips), youth teams, scout badges and birthday parties keep younger climbers busy. Every week there's yoga on top of the boulder wall, a women and non-binary meet-up and a free climbing session for people living with Parkinson's, and each month brings an LGBTQIA+ meet-up and an adaptive climbing clinic run by the Pennsylvania Center for Adapted Sports. Discount days run on Mondays, Wednesdays and Friday evenings.
