    We had a wonderful stay at Mountain River Ranch! The hosts were super helpful and accommodating. We may have been the only tent in the campground, but they gave us a choice location. We had our grandsons with us and they had the time of … More their life swimming and canoeing in the pond. Our dogs were also welcomed and there was plenty of space for walking them. I would 110% recommend this campground and we will be back! Oh…did I mention the amazing, clean bathroom/shower facilities?! 😊

    Campsite was clean, hosts were friendly and helpful. Went out of their way to make sure my kids had kayaks to play with in the pond. They had live music while we were there and the ice cream trailer was very satisfying on a hot day. Would … More stay there again, and would recommend to friends.

    Mountain River Ranch is a nice, quiet RV park located near the Snake River and at the base of the mountains. It is a lovely setting and the owners work really hard to keep it clean and inviting. The only reason I didn’t give it 5 stars … More is that it doesn’t have sewer at the individual campsites. For a long stay you either have to hook up and go to the on site sewer dump or have a local septic service pump your trailer
    There’s great places to walk or ride your bike right from the campground. I’ve seen white tail deer and a big variety of birds
    Overall this is a nice campground and I would recommend it to others
