This part of the island has been declared Historical, ecological, tourist municipal reserve. This excursion offers you much more than traditional walks as it combines different aspects as enjoying nature, a historical, cultural and scientific-technological aspect too.

It can be added that many years ago, the island was historically relevant -during 1949/1952- because the Austrian scientist Dr. Ronald Richter had chosen it to build his research laboratories for controlled nuclear fusion. This research was the first western world project about nuclear fusion, sponsored by the late president Juan D. Perón. However, after several changes in its former plan, the "Huemul atomic project" came to an end.

We can still see nowadays the "twin labs", chemistry lab, Richter's lab, the reactor's building, the energy plant, Richter's house and the square. Some of its buildings were already finished by the time the project ended, but others were still under construction.

We then return to Bariloche town by boat.
