I found Bryce Valley Ranch RV and Horse Park at the last minute, and was pleased how quiet and clean it was. I was also pleased with the special I got for the month of August. Their special was stay 1 night, get the 2nd night free (I stayed 4 nights). The other part of their special was that I got 10% off my bill.
This is a new park so a lot of the trees for shade are young, but this park is centrally located to a lot of excursions around Bryce Canyon and such. Very clean bathroom/shower facilities and the staff were very helpful with me planning my day trips.
I had a great time!
