using a rope, it is called abseiling or rappeling.
To abseil means to descend a cliff, rock, mountain face or other vertical surface by means of a double rope anchored above oneself.
To safely rappel down a cliff, you should first ensure you have the proper equipment, including a harness, ropes, and a helmet. Find a sturdy anchor point at the top of the cliff to attach your rope to. Double-check all your gear and make sure it is properly set up. Slowly lower yourself down the cliff, using your legs to control your descent and keeping a firm grip on the rope. Always maintain three points of contact with the cliff at all times. Communicate with your partner if you have one, and take your time to descend carefully and safely.
