what's the best ski resort in tahoe

Depends on what you're looking for (e.g., upscale or family style? Smaller/cozier mountain or large? etc) & whether you're interested in North LT or South LT. So the real answer is that I'd rephrase the question more specifcally based on what you're looking for in a ''best'' ski resort, & re-ask.

That said, my personal opinion is that the best resort is Squaw, hands down. It is the largest mountain with the most diverse terrain, something for all levels. It does not have any major gondola bottlenecks (like Northstar) which translate to long waits. And it is got nice amenities - the chicken sandwich at Tantara bakery in particular is off the hook.

It really depends on your taste, but IMO Squaw Valley is the best for several reasons: it is one of the largest resort in Tahoe, offers wide variety of fun and challenging runs, is relatively near Reno (ie, cheap lodging), and last but not least, has night skiing!

l love the night skiing. l can drive up from the Bay Area in the morning, get there by noon and do a half-day which includes night skiing until 9pm :-D
