Visit Mount Tronador
From Bariloche, a scenic road winds along the lakeshore to emerge from dense forest at Ventisquero Negro, a ‘black’ glacier formed by the mixing of ice with crushed rock. You’ll pass Lago Mascardi, where a rich variation of hues from sea green through turquoise to deep blue has earned it the nickname, ‘Lake of Seven Colours’.
Continue to the base of Tronador Mountain, known as the ‘Thunderer’ because of the vast ice and rock slides that can frequently be seen and heard here. Before returning to Bariloche there is time to climb to the Los Alerces waterfall, where glacial meltwater crashes down into a jade river.
