This site is across the highway from the entrance to the Shoshone Ice Cave attraction on highway 75. If you are heading north on 75, turn right at the gift shop on the right side of the road. Proceed down the gravel road east and make a left at the first curve to the left. Right after the curve, you'll see a small concrete bridge on the right that crosses the canal. Park in the open area just across the canal. You are between the canal and the Big Wood river which is dry in the summer months. What's nice about this spot is privacy and isolation. It's a great spot near both Shoshone Ice Cave and Just a few miles from Mammoth Cave. The site is next to an old lava flow which is incredible to see and explore. Wildlife we saw includes deer and owls, wood peckers and many other birds.

There's a couple bars of Verizon here. Nice hiking and exploring the river bottom and some water-carved rocks. Just a few miles north on 75 is Black Magic Canyon which has some larger more impressive water carved rocks. You can hike the stream bed. There is an information sign  about this at the intersection of 75 and Black Magic Road. Be careful as the water agencies can release water anytime. They suggest you call before hiking the stream bed. By the way - free RV dump station in the town of Shoshone 16 mile south.
