The roads around this place are not maintained for a regular car. That comes from the US Forest Service, who grade every road by the kind of vehicle it is looked after for. Those records cover the roads nearby. They do not cover the last stretch in to the campsite, and nobody has checked that part. Treat this as a warning. We are not promising what you will find when you get there. If you have driven it, tell us what it was like and we will say so here.

What is near here

There is another spot of ours within reach, and some better-known places further out.

Every distance on this page is the driving distance. A short distance can still take a long time. The road may be closed for the season, covered in snow, or washed out. Many of these roads are dirt. Plan your route before you leave home. Out here there is often no phone signal to look it up on the way.

Nearest town and supplies

Ennis is big enough that you’d normally expect fuel and somewhere to buy food. Nobody from here has been to check, so don’t count on it if you’re running low.

Have you been here?

Fees and access change, and the records do not always keep up. If you have been, tell us what you found.

The thing we cannot get from any government record is what the drive in is actually like. If you have done it, this is the most useful thing you can leave behind. We read everything before it appears, and we print a first name with it if you give one.

Where this information comes from

The description on this page is ours. The facts in it, and the fee and facility details below it, come from the Forest Service’s own records, read in August 2026.
