Hey I live in an area where I do not have anyone to belay me for rock climbing. There are some perfect spots to climb where I have a perfect anchor on top that I can connect the rope to. What is the best way to go about climbing the wall and belaying yourself to climb the wall. I've seen a variety of youtubers use different techniques where some use only a grigri and others use that as well as trxion pulleys and I was wondering what is the safest and best way to do this?
