My friend is a member of Mission Cliffs Climbing & Fitness, and because his membership came with two guest passes a month for free, he decided to bring me along. I had a load of fun as I did wall-walling for the first in my life. The staff there were awesome - motivating and very friendly. I think it's a bit pricey, but that's probably only because I'm not used to paying for these types of activities. I recommend wall-climbing to anyone who is looking for a new type of activity to try, and if you are planning to go wall-climbing in the San Francisco Bay Area, I highly recommend Mission Cliffs Climbing & Fitness.
