Poison Spider 3.5
This trail is one of the Moab classics, with both rock crawling and great scenery. Be prepared for a lot of company as this is a popular trail.
There are rim overlooks where you get a great view of Moab and a rock that looks like a pig with piglets. Also an arch and a cave. The trail is rated a solid 3.5 if you take all the go arounds, and extra credits can raise the difficulty quite a bit. Something for everyone.
