Stayed 1 night

We absolutely loved our stay at Riverside Inn & Spa! We were only there for one night, but it was such a perfect romantic getaway. The hotel is an adorable, full-service boutique hotel with so much character, and we especially loved that it is adults only. The private pools were one of our favorite features. Having a pool completely to ourselves made the experience feel so relaxing and intimate. We also loved the little café. The food was delicious, especially the quiche in the morning! Dinner at the restaurant downstairs was another highlight. It was romantic, cozy, and the food was phenomenal. The rack of lamb was incredible, and the duck had perfectly crispy skin and was packed with flavor. We also loved the history and character of the hotel. It has this wonderful old-West feel that had us imagining what it must have been like in its heyday. We ended up diving into the history of the property and loved learning about it. The beautiful river overlook was the finishing touch. Everything about our stay felt cozy, romantic, unique, and special. We would absolutely stay here again!

The best way to think about the Riverside Inn is to imagine that you’re driving through southern Italy and come upon a charming but old and not terribly well maintained hotel. Your room is OK, not great, but you are able to have cocktails and a quite good dinner outside on a lovely patio next to a flowing river. You can also soak in the lava spring hot tubs in the basement. Pretty good deal.
