My wife and I did this as part of a side trip on our visit to Zion National Park. This was the first time either of us have done any rappelling whatsoever. We had a blast. It was a very beautiful area.
I hate the dates on these... I never remember the exact times we have gone, but have been there many times. Done Squirrel Canyon to the arch as well. The hike from Water Canyon all the way to Eagle Crags was awesome!
