Backpack Central Patagonia's Cerro Castillo Circuit & San Lorenzo Basecamp

Backpack in the remote central Patagonian Andes, circling rugged Cerro Castillo and following the climbers' route to the lonely basecamp for Cerro San Lorenzo.

Cerro Castillo (2675m) and San Lorenzo (3706m), two colossal mountain massifs of rugged spires and hanging glaciers, attract international climbers and adventurous trekkers but in far fewer numbers than the popular parks to the south.  Still, the peaks and glaciers are no less spectacular and we’ll have them mostly to ourselves!  The four-day 62km circuit trek around the formidable Cerro Castillo attracts solitude-seekers put off by the more crowded backpacking trails in Torres Del Paine further south. The route passes three major glaciers, turquoise lagoons and high alpine passes favored by Chile’s endangered huemul deer. The San Lorenzo basecamp trek samples the climbers’ route to the summit with a hike into the remote Toni Rohrer refugio at 1000m, with dayhikes from there to a high pass at 1900m on the climbers’ route, and to a starkly lovely lake in a deep trough ringed by half a dozen glaciers and resounding with icefall.
