Boysen State Park & Sinks Canyon, Wyoming Questions

I spent one night last September Boysen SP in the lower CG. Seemed a little pricey for non-residents at $7 more. I don't recall mosquitos but the biting flies were bad until it cooled off and the place a bit buggy. They had a few spigots and decent grassy areas. I explored around the dam upstream. There's a railroad on the other side of the river with a few trains but no horns blaring. The year before I passed through the area and stayed on the western side of Boysen at Lake Cameahwait. It was free boondocking. There are several spots on the south side of the lake with pit toilets and you can fit 2-3 campers in a spot. there were nice shelters but what looked like a hoard of barn swallows and just made a mess of them. It was a little buggy until dark. There is a paved road almost all the way there but watch for large potholes.

We have camped in Sinks Canyon twice in our 24ft Class C. Check with Google Earth and you will see that there are three campgrounds within a mile or so along the river. We stayed at the Popo Agie Campground, which is the first one you come to. Not a lot of sites large enough or level enough but we got lucky both times. We didn't check out the other two campgrounds. Google earth also shows boondocking sites further in near and beyond Frye lake.

There are some hikes from the campground and the Sinks and Rise are interesting to see. For something different you could make a 1/2 day trip to South Pass City a couple of miles off route 28. They have tours and some hikes.

We've stayed at the Sinks CG several times. Always enjoyed the stay. With your rig you shouldn't have a problem, if sites are available.
