We had a hard time finding our way to and around this park, as the directions in Woodall's were inadequate. As stated in another review, going west, drive to the top of the hill and take a left on to Lakeshore Drive. The map from the grocery store did not indicate where the main campground was, so we pulled down by the lake, and boon docked there. The site was lovely, but we had some trouble leveling, and access by the road was tricky for our 40 foot RV. Still the place is unusually beautiful, and we would surely stay here again. The site is close to Independence Rock, an icon and important stopping place for emigrants on the Oregon Trail. We camped here in a Motorhome.
This is an excellent alternative to the private (tight and expensive) campgrounds in Casper. It's 28 miles SW on Hwy 220 and run by Natrona County. There are some full hookup sites (though not on the lake and crowded), but for a day or two of dry camping, there are many sites where you pull up right by this incredible lake, with a fire ring and shaded picnic table - for just $7/night. We camped on the west side of the lake - go beyond town of Alcova about 1 3/4 miles and take Lakeside Drive. Wonderful map available at the CR407 turnoff (Alcova) at Sloanes General Store. They have all the park info and were a great help. The views and privacy were absolutely wonderful - we wished we had more time to spend there. We camped here in a Motorhome.
