Our stay at the Riverside Inn was everything we hoped it would be. The staff were all so friendly, helpful and always available. Our room was spotless and had a brand new comfortable bed. I would stay here again!

We stayed for one night on our way back from Rushmore on a road trip. Our plan was to stay next to the hot pools in Lava Hot Springs since we got online tickets to use that facility. The Riverside Inn is a historic property conveniently located with a friendly staff. It wears its age well but it is part of the experience. It doesn’t have elevator or luggage cart however the staff offered help with our bags which was very nice. Dave went above and beyond to make us feel welcomed in the property. We tried their Portneuf Grille&Lounge and were amazed with the espresso drink prepared by Will. The breakfast was cooked to order and delicious, thanks to Colter and Alexa for making it so enjoyable. Overall we had a great time at the Riverside Inn.

All you need for a comfortable nights stay, plus the history! Hot spring tub rooms were relaxing and private, dinner was sublime. Plus we enjoyed breakfast at the onsite coffee shop. Snowed 10 inches when we were there. Staff kept us safe and warm. In fact, all the staff we met from the hotel were very helpful, and enjoyable company. Thank you!

Great little hotel, friendly staff, spacious rooms and the private soaking tubs are very nice. We ate at the restaurant downstairs and though it's a little pricey, the food was delicious and worth it for a special occasion.

The whole trip and experience was 5 star!! From the time of check in with Dave who was very helpful and informative to the dining and lounge experiences with Will who was an excellent bar tender best in the area and as well as Rachael and one other individual who was waiting tables. The inn is very unique and a one stop for everything. The little eatery within the Inn was fatastic as well not a bad thing on the menu. The final checkout with Cat was also a great experience she is a very fun and casual person. All of them were very friendly and professional and treated you as if we had met already before. I will definitely be going back to have another 5 star experience! Thanks to everyone there for making the stay a very memorable one.

We very much enjoyed our stay at Riverside Hot Spring. The staff was friendly, the on site mineral baths were very enjoyable and easy to book and the food was very good. For us, it was amazing that we could have our dogs join us on the trip. Thank you!
