In this habitat, the Reserve carries out conservation actions, so it will be the right time for the guide to start the second talk, in the field of Biological Sciences.

Finally, in the third and last section of the path you will border the lagoon for another 800 meters, getting close enough to the imposing Cagliero Este glacier to contemplate the atmosphere of hanging glaciers and moraines that gives rise to the third talk in the field of Geological Sciences.
