Rope Climbing

What is Top Rope Climbing?

Top rope climbing is a great way for beginners to learn how to climb on a rope, although it doesn’t come without challenges for more expert climbers looking to hone their skills. A rope is tied to the climber's harness which then runs through an anchor at the top of the route and back down to an approved belayer at the bottom of the wall. As the climber goes up, the belayer tightens the rope.

A Sender One Top Rope Belay Card is required to Top Rope Belay. New climbers can learn how in our Intro to Climbing Class!


What is Bouldering?

Bouldering is climbing without a rope on shorter walls. All you need are a pair of climbing shoes and chalk if desired.

No experience is necessary, but here are some things to keep in mind:

  • When you're done with a boulder problem, either climb down (recommended) or if you decide to jump away from the wall, tuck your arms in and land on your bottom while rolling onto your back in one motion.
  • Be mindful of your surroundings and those climbing around you.
  • Warm up properly.


Take a class that covers all you need to know.

Intro to Climbing Class

This 1-Hour class will teach you how to tie into the rope as a climber, top rope belay using a GriGri, use climbing commands and perform checks to minimize risk while climbing. After completing this course, you will be able to climb independently at Sender One.  This class includes a day pass and rental gear. Students must be at least 14 years of age to take the class.  Reservations Required.
