I like the artificial walls, but I climbed a real rock face once and it was NOT FUN! They thought I was really good cuz I guess I got up the easy “trail” really fast, so they told me I NEED to try the next one. So, I did, and it was painful and frustrating and even when I got to the top I felt like I hadn’t done much, cuz many places I’d sort of pulled myself up an inch at a time and the belay held me in place another inch higher while I lost my grip again.
