Rock climbing?

There is rock climbing, and there are several ways to learn the rock climbing skill. The best and fastest way is to have your sim climb one the natural rock walls that are found in Mt. Komorebi. Now if your sim just starting out in the rock climbing skill. You'll need to start them out practicing on the shortest rock wall. You can find it on the left if you are facing the bottom of the bunny slope. There are 2 medium rock walls which your sim will graduate to once they reach level 3 or 4 in the rock climbing skill. One is at the top of the ski slope, not the bunny slope, the ski slope. You have your sim ride the tram to the top of the ski slope. Once at the top, have your sim go left and follow that path to the medium rock wall there. The second medium rock wall can be found on the left just inside the entrance to the hiking trails found in the neighborhood where festival of lights is held.
