Climb Patagonia With Alpine Ascents
I very much enjoyed the expedition. The overall quality was excellent, particularly given that this was AAI’s first expedition to Cerro San Lorenzo. Everything from lodging to group gear to food to the itinerary were well planned and executed and the guides were adept at making changes as circumstances dictated. The experience was both fun and challenging.
First climbed by 60-year-old climber Padre Alberto Maria de Agostini, Cerro San Lorenzo is a demanding peak with just rewards. At 3,706 m (12,159 ft.) this is the second highest peak in the Patagonian Andes. It has heavily glaciated terrain in an extremely remote location. Rising out of the Patagonian Pampa (plains), east of the Campo de Hielo Norte (Northern Patagonian Ice Field), Cerro San Lorenzo is blessed by a relatively sunny micro-climate and generally experiences better weather than much of wind-whipped, rainy Chilean Patagonia. With more balanced weather throughout the region, Cerro San Lorenzo is one of the few accessible peaks, adding to the allure.
Alpine Ascents’ expedition to Cerro San Lorenzo provides an excellent opportunity for fit and intermediate climbers (i.e., climbers who have had a strong performance on our 6-day mountaineering course or better) to apply the skills learned in our courses or on other glaciated peaks, in an international setting. Along the way, expedition members will experience the unique culture of Chilean Patagonia – with travel along the Carretera Austral (Southern Patagonian Highway). Expedition members will interact with horse packers and spend time around a campfire partaking of a traditional Chilean asado (barbeque).
For climbers intending to climb Denali with Alpine Ascents, this expedition can also serve as an outstanding ‘Denali Prep’ course – this location provides appropriate weather for the training and our guides are prepared to focus on Denali specific curriculum.
Beyond the prolific first ascentionist Padre Agostini, this mountain has been the climbing objective of many ambitious mountaineers, including the French Groupe Militaire de Haute Montagne. We are able to attempt to summit Cerro San Lorenzo by the traditional “Agostini Route” used by the first ascensionist. Mule and 4×4 support will reduce pack weight at points and augment the climber experience.
The January 2018 Expedition was a success. Climbers were thrilled with the experience – due to the scenic quality of the Aysen region of Patagonia, the opportunities for cultural interaction, and the beauty and remoteness of the mountain – and despite no summit several climbers planned to recommend this expedition to their friends next year. Also, perhaps because of no summit, at least one climber reports that she is planning on joining this expedition again next year.
For 2018 we have added four days to the expedition to increase chance of summit success, and are promoting this climb as an excellent location for preparation for Denali.
Definitely believe that this is a trip many climbers would enjoy so I hope it becomes offered annually. Absolutely special because of the remote location and spectacular landscape. Great Denali Prep course. Totally possible I will join this climb again in the future! Can’t thank all of you enough for making this trip happen. 2018 Climber
