Near the eastern end of Lago Fagnano, the road splits: the left fork is the more scenic, old, unsealed RN-3 route, which cuts north across the lake along a splendid causeway; the right is the RN-3 bypass, the more direct route to TOLHUIN, the region’s oddest little town. Created in the 1970s, Tolhuin was designed to provide a focus for the heartland of Isla Grande – indeed, the name means “heart-shaped” in Selk’nam – but as a place of unassuming houses that hangs together with little focus, it has an artificial commune-like feel. It does, however, make a useful halfway point to break the journey – as most buses do – between Ushuaia and Río Grande.
