What's everyone talking about?

Anybody can indoor rock climb!  We have easy walls, hard walls and everything in between!  As the climber ascends the wall, a qualified belayer, anchored to the floor, manages the rope.  The belayer takes up slack, stops any falls, and safely and slowly lowers the climber once he/she has reached the top.

At boulder morty's, we put safety first!

We have taken the highest possible precautions to insure the utmost safety to those who visit and climb in our gym.  Top rope climbing is when the climber ascends up to the higher points of the wall using a rope for safety.  The rope is attached to the climber's harness using a pre-tied figure-8 knot, then goes up and over a secure belay bar at the top of the wall.  A partner, called a belayer, holds the free end of the rope, taking up slack through a "Gri-Gri".  If the climber falls, the Gri-Gri automatically locks and breaks the fall, with the belayer braking the rope as well.

Our harnesses are Petzl Club harnesses, which feature an automatic "double-back" buckle system.  This ensures that when the belt is adjusted to proper fit, the harness is locked and will not loosen.

All climbers and belayers receive in-depth instruction and safety review prior to climbing.

Each child will receive safety instruction prior to climbing as to assure a positive and safe climbing party for all!
