The first part of this trail goes through the forest and some wetland sectors, in a low difficulty route, estimated in 1 hour and a half until arriving to the waterfall. The beginning is done by crossing a log bridge over the Lasifashaj River. The second stage is of medium difficulty, and requires a greater physical effort, as it involves a climb up a rocky slope where ropes are used to help, both for the ascent and descent. Once out of the vegetation limit, you will go through rocky paths that, in some moments of the year, can be covered by snow or ice. There are some pircas and stakes that mark the direction to the south, where the Laguna Submarino is located. In both stages it is essential to wear boots, warm and waterproof clothes. Other information of interest: One kilometer away from the entrance, near the Lasifashaj River, there is a wild camping area with bonfires. The name of the lagoon is due to the shape of the hill where it is located, since according to the perspective, it resembles a submarine. Main attractions: Tierra Mayor Valley, Lasifashaj River, Submarine Lagoon.
