WY: Keyhole State Park

Just across the Wyoming/South Dakota Border is a picturesque state park campground bordering a reservoir with rocky cliffs, and with two personalities.

If you have never done yoga outside in a beautiful setting - try it!  (Note:  We will be doing a blog post on yoga soon.)

We very much enjoyed our one night at Keyhole State Park as a stay on our way to Bighorn National Forest.  Camping here allowed us to cut our driving time to Bighorn into shorter days, and take one last shower and dump our tank one more time before we were off-the-grid in the Bighorns for four days.

That said, campers beware.  This is a large campground with various loops dispersed around the reservoir and its main use seems to be from locals with large RV's, generators, and groups looking to party/socialize (especially on the weekend).  We arrived on a Sunday afternoon  and noticed a lot of mess/garbage left over by weekend campers.  Our advice:  arrive for an early week stay if you come.  After we arrived, many people packed up and left (as late as 7pm!) - the generator RV next to us was one, leaving us in bliss to have the place nearly to ourselves and enjoy the our idyllic campsite.  The perfect set up to practice yoga out our back door the next morning!

Our recommendation in the Pronghorn loop would be sites 20 and 21, and for more privacy ~ 19.  (loop map here)
