Havent been in june/july, but I have been in Aug/Sept for the past 2 years, and going snow again this year. The snow is unbelieveable, and there are no lift lineups, and things don't get tracked out by noon, (or like here in whistler, after an hour) but you'll have to put up with older lifts and tbars. I've been to termas de chillan from around aug 10-sept 5 for the last two years and we always seem to get these storm cycles which dump 3+ feet in 2-4 days, and then its bluebird. I've got a photo or two uploaded, but it's well worth it. This past year, we had so much snow the entire top tbar was buried, along with a snow cat for weeks. How often can you say 20+ft dumped over your ski vacation?
