Hot spring waterfall
Beyond the castillo, the broad sweep of Lago de Izabal opens before you, with great views of the fertile highlands beyond the distant shores. Some 25km from Río Dulce, a hot spring waterfall in land owned by the Finca el Paraíso, 300m north of the road, is one of Guatemala’s most remarkable natural phenomena. Bathtub-temperature spring water cascades into pools cooled by a separate chilly flow of fresh river water, creating a sublime, steamy spa-like environment where it’s easy to soak away an afternoon. Above the waterfall is a series of caves whose interiors are crowded both with bats and extraordinary shapes and colours – made even more memorable by the fact that you have to swim by torchlight to see them (bring your own flashlight).
