I really wanted to like Portillo, but frankly it's mediocre in most aspects. The vertical is not great with all lifts accessing less than 1,000'. It's very difficult to expand that number because the resort is divided in half by the Inca Lake. The best skiing is the "bowls" - really just long chutes that you reach via 4/5 person poma lifts that whisk you up. There are 3 of these, and from them you can traverse or climb to some others. In most other ambitious ski resorts these would all have chairlifts and better planning of layout throughout. The care-taking of the mountain is seriously lacking, with minimal grooming, little signage of any kind, and complacent staff attitudes. The "trails" number less than a handful and get boring quickly, especially after skiing/boarding them for a day or two. If snow is iffy there is hardly any snowmaking backup - a serious problem. Most folks stay at the Hotel Portillo (except for the budget minded - there's a bunk bed building) which is basic; very modest rooms including 4 meals daily which are surprisingly bad and sometimes near rancid. I don't know how it's partnered up with Rockresorts, other than a stunning location (it has nothing in common with those five star resorts). As someone who has skied most everywhere I'm glad I visited for my own education, but I'd find it hard to recommend this place except for the most inquisitive, it simply doesn't live up to expectations. From what I understand, Valle Nevado is a better choice, and when I return to S.A. it will be my next.
