Momentum Katy, a 36,000-square-foot indoor rock-climbing gym, opened July 29 at 25410 Katy Mills Parkway, Katy. The gym is the first Texas location for Utah-based Momentum and offers REI’s Co-Op Climb.

REI and Momentum offer classes while the co-op will organize rock-climbing trips to the Austin area. Momentum Katy offers bouldering, moderate climbing, more advanced lead climbing and an auto-belay climbing section. Belay climbing does not require a partner on the ground level to counterweight a climber via rope.

Day passes, memberships, party reservations and equipment rentals are also available. 832- 437-9091. www.momentumclimbing.com
