Spending two weeks hiking in northern Patagonia, this was my favorite of all hikes. It is an all-day adventure so plan accordingly. There are two ways to do this hike: we started with the ski lift up from Bariloche, then hiked Catedral Ridge, then went down to the Frey Hut, and then a solid descent to the shores of Lake Gutierrez. I loved climbing over and around the boulders while on Catedral Ridge but you shouldn't do Catedral Ridge if you are scared of heights or subject to vertigo. The view was the most spectacular that I've seen. Then the scenery changed while hiking the valley to Frey Hut - lush green vs barren stones. The descent past Frey Hut was all wooded and shady so yet another type of scenery, and some relief from the afternoon sun. We ate our picnic lunch at a small lake as we hiked down Catedral Ridge towards the valley. We were able to refill our water bottles and use the restrooms at Frey Hut, and I bought a cold Coke. We had a guide but I think it could potentially be doable without a guide if you have a good sense of direction and at least a field guide.

We were exhausted on arrival at the refugio, and were thrilled to find such a welcoming spot. Set beside a beautiful little lake where you can have a dip to cool off, followed by one of their really superior pizzas- they were also serving a hearty looking stew- and perfect night sleep in their large dorm, where everyone lines up in their sleeping bags ( they have some available there). We were really glad we got a spot in the refugio, as the campsite looked really really uncomfortable- a rock bed on a steep enough slope

This is a hike that requires a certain level of fitness. I saw people struggling with the uphill at the end of the long hike, several km up. However, slow and steady get the job done. Beautiful views and wonderful spot at the top to rest. We saw a condor flying above us at the refugio which was the icing on the cake after 3 hours hiking up.
