Riverside Hot Springs Inn is an enjoyable, quiet hotel. Like the town of Lava Hot Springs this is laid back and rather unique. Riverside is not a hoity-toity hotel, rather a older facility with a new life. Rooms are comfortable and well cared for. The mineral spring hot pools are a treat that guests enjoy. Breakfast is very tasty and quite different than the typical hotel breakfast menu. The accompanying Portneuf Lounge and Grill provides well prepared meals and includes a special happy hour menu when you are looking for a lighter meal. All of the staff that we met were quite friendly and most helpful. This is a special place where every one knows your name. This was out 2nd visit to Riverside Inn and we look forward to our next opportunity to visit.
