REHL stands for Rancho Equine Hermanos Lopez - Basically the Lopez brothers horse ranch. It is truly an operating horse stable and rodeo facility with a good restaurant, two very nice pools (swim up bar, water falls and slides), and clean, comfortable and new motel rooms. The staff is very friendly, but speaks almost exclusively Spanish.
There are lots of outdoor activities: whitewater rafting, horseback riding, zip lining, etc.. in the area and they will pick you up and deliver you back to REHL. Also a half hour drive to La Fortuna and all the Arenal activities.
A very unique "hotel," but was a very enjoyable base camp for our family of four.
