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.
If you’re looking to explore a lesser known area of Zion National Park and avoid the crowds, this is the place for you. Located 30 minutes from Zion National Park, on Kolob Terrace Road (0.1 miles once on Kolob road on the right hand side). The campsite is located near a stream and is absolutely beautiful. Free to camp here, no permit required, first come basis. Fire pits are available throughout.
For those of you who are planning on hiking the Subway, this is the perfect place to camp as it only located a few miles from the Subway Trailhead - Left Fork Trailhead.
