We travel about an hour and a half to Rincón de la Vieja National Park; because of its volcanoes it boasts hot bubbling mudpots, hot bubbling "water" pots, and hot fumaroles. To explore some of the park, we take a trail from the Las Pailas station (the cauldron circuit). Aaron soon dubs it "the death march" because of the dry Guanacaste heat. Afterward we travel to "nearby" Borinquen Mountain Resort to use their natural spa for the afternoon. Jen even treats herself to a massage at the spa. It is the perfect way to recover from the death march.
