Hotel Hacienda Guachipelin Private Hike to La Cangreja Waterfall is a 5-hour activity which takes place within the Rincón de La Vieja National Park. The hike features a 5km walk along which visitors can potentially spot wildlife such as monkeys, iguanas and birds. Once at the waterfall, visitors can enjoy a picnic and explore the area surrounding the waterfall. This 40m waterfall features a pool of blue water at its base, which is a result of volcanic copper minerals reacting to the water.
