Real Customer Review:

“Mountain River Ranch was the perfect place to set up for a couple nights of camping. The tent site area was large and nicely dispersed, and right by a bathroom! The facilities were clean and well kept. We met the owners of the property and they were so kind and offered some insight to some hiking trails nearby. I would highly recommend a visit whether in a tent, RV, staying in a cabin or their yurts. Thanks for a great experience!” – Ariel Alexander
