Easy to hike.
Easy to get great photos.
It's one of those places you can drive by 1000 times and fail to go in and explore. It's pretty darn cool. I recommend the 5K trail for an easy rolling hike or bike on a path. For a bit more fun, do the obligatory "Hole in the Rock" especially at sunset or go over to the Hunt's Tomb for a more unique photo opp. If you do Hole in the Rock right, you can get a killer shot that looks like you are surfing the rock...
