It's funny you mentioned wanting to do it since you saw it from Cuyamaca. One of the first peaks I did in San Diego was Stonewall. I saw Cuyamaca from it so I came down and hiked it as well.
Didn't realize there was a less step trail. Have taken dozens of elementary aged kids up the steeper route and they all made it.
Great hike for all ages! And on a clear day can see all the way to the islands.
