This is a unique property a few minutes down the road from the park entrance. Eric runs the place and is very helpful. We stayed in the main building, but there are contain rooms, as seen in the picture, scattered throughout the property. We only stayed for one night, and really enjoyed our dinner with the other guests. Travelers from many countries came together for a nice meal and good conversation. It helped that most spoke English.
The park was great. We did the 3k loop of volcanic activity like geysers, bubbling mud pits, and volcanic rock, and the 10k in and out to the waterfall in one day. Get there early because the trails close by mid-day.
