I've only been skiing like 5 times. But my second time was at Arapahoe. I could be mistaken, but it's pretty much all difficult trails. Not much if you're not a good skier. I ended up getting sick. So with the elevation, any movement was a Herculean effort. I spent a lot of time laying in the snow trying to cool off. Ski Patrol kept asking if I was ok and needed help getting up.
Also, it was June 1st and I dressed like a person who hadn't every really been skiing would dress. For cold weather. It snowed 3 fresh inches overnight and was about 80 degrees by noon. People were skiing topless. Dudes.
Anyway, if you're a good skier, probably a fun place. If you're not a good skier, it wasn't that fun.
