These are cliffs that over look part of the lake. Often times daring Argutus group members will go cliff jumping from here, they're also where they light off fireworks for the camp. Great for star gazing as well.
There are some flat plains up on the mountain where Argutus group members fight and spar. It's where they train often times. From the plains there's also a small hidden cave used as a second entrance up high to the caverns and the hot springs.
