The lagoon of Huallhua is considered as Eco Tourism Reserve of Peru due to its high Biodiversity and forms part of the Landscape Reserve of Nor Yauyos Cochas. The lake has waterfalls in the form of platforms where the water has a crystalline turquoise color with abundant fauna such as trout, diver, herons, yanavicos, huallata, wild ducks. The edges are surrounded by local flora such as quenual, karkac, taya, taya-taya, huamanpinta, quishuar, zapatito, among others. In some places, the vegetation grows so much and covers the path of the lake making believe that the water flows from the ground.
