The biggest loot concentration is waiting at the summit and that's where you'll want to focus your efforts, but there's a method to this (rushing straight up rarely works out well). First make sure you've got a hacksaw since those cargo containers won't open themselves - interesting fact: they actually protect the gear inside from degrading over time. You'll need to establish yourself at the mountaineer's hut, which makes a perfect base camp while you get organized.

Getting to the summit requires some planning because those rope climbs are pretty demanding. Make sure you've got emergency stims or coffee ready, and warm clothing is absolutely essential up there (the weather can turn nasty in seconds). The main path takes you past several cargo zones, and smart climbers check these first since they often have supplies you'll need for the final push. Something worth knowing is that the actual loot you'll find varies by difficulty - if you're playing interloper, don't expect to find any firearms up there, but you might get lucky with an expedition parka or some high-quality tools.

The descent can be just as tricky as going up, but there's a neat trick where you can use natural ledges to work your way down without using ropes (though you might take some minor damage). Oh, and if you're playing with the new content, keep an eye out for those signal void supply caches near the hut, they've added some interesting new possibilities to the early game strategy.
