Huge resort, lots of runs, varied runs, lively village, fast lifts
crowded runs in peak season, not the cheapest
I went to Heavenly in February of 2009. I flew from Gatwick to San Francisco; it was a pretty heavy flight and took a long time and the transfer was around 5 hours. BUT! It is well worth the travel for the sheer volume of runs that the resort boasts. Plus, the runs are varied and cater for most skill levels as there are some impressive greens to cruise and some pretty intense double black diamond tree runs to test your skills (experts should head on over to Motts and Killbrew canyons).
The village itself is very large for a ski resort. Much larger than your typical European resort. But if you like a more lively resort then Heavenly delivers. There are plenty of lively bars with live music and if you enjoy placing a wager then there are a number of casinos for you to check out. There are also plenty of restaraunts, offering a wide variety of different food. The centre of the village around the high speed heavenly gondola are all designed in a traditional look cabin style that gives the village a very traditional vibe . Also if you want to upgrade or simply change your gear there are plenty of well stocked sports shops to check out.
The instructors are also fantastic. They are so friendly and helpful.
Oh...and most importantly the snow was fantastic. The best I have experienced, the light but thick powder was a dream to carve up (10,000ft at the summit, which you could pretty much reach in a few lifts). Thick snow all the way down into the village.
If you are thinking about America, Heavenly is definantley a resort you should consider.
