My children (ages 7, 10, 13 and 13) climbed this. I set up a top belay station attached to two bomber trees. Each would rap down (with a belay line connected) and then climb back up. It's listed as a 5.1 but seemed more difficult than the 5.4 Sand Box Corner. There aren't many holds for the first 30 feet. The children liked it because they could feel more independent.
