Very hot in the summer and busy during the fall as well although it is a bit more pleasant. It lies close to the creek at the very beginning of Kolob Terrace Rd. on the right hand side. There are many places to park a small RV or trailer but there are also spots to pitch a tent! These are completely primitive sites and do not have fire rings or bathrooms at the sites. They are free however and offer great access to Zion NP and easy access to the Subway if you're going to the route from the bottom.
