Message received from the guys in South America - they will be at Cochamó on 15th Feb and I should hike into meet them at the crag when I get there. So - how to get from Cochamó to the campsite? There's no way I can carry the 30 kgs or so that my kit weighs so I expect I'll have to arrange the services of some chap with mules once I get to Cochamó itself. Some research to do methinks.
