O Circuit

The full circuit of the Paine massif — the back side that the W trek does not reach, joined to the W's southern spine. Walked anticlockwise from Las Torres, it crosses the empty pampa to Serón, follows the Dickson glacier's lake, and climbs over Paso John Garner to come out above the Grey glacier, which fills the view for the whole descent. [Route details] Loop · start and finish at Las Torres 92.3 km · anticlockwise · 39 m to 1,166 m at Paso John Garner (47 km) Usually 7 to 9 days [Round the loop] - Campamento Serón 13.4 km · Refugio Dickson 31.7 km · Los Perros 43.1 km - Paso John Garner 47.3 km · Refugio Grey 57.6 km · Paine Grande 68.0 km - Campamento Italiano 75.3 km · Los Cuernos 79.8 km [Good to know] - This is the loop itself. Walkers usually add the two W arms — the towers and the Valle del Francés — which brings the trip to about 120 km; both are in the W Trek route published here. - The back side is one-way only, anticlockwise, and opens later in the season than the W. - Elevation is sampled from a terrain model, not recorded on the ground.
