Uncrowded, very charming, lots of trail variety
Not as big as Killington, Not open for as long as Killington
Pico is great. In some aspects it's way better than Killington. It has a nicer atmosphere and is way less crowded. There is way less trudging between lifts. There is a lot of great, deserted terrain off the Little Pico Triple. I loved being the only one on B Slope and navigating the Rocks on A slope. The Outpost Double Chair is my least favorite chairlift ever because it is tough to get on, but it had some great trails near it, like Bronco and Stampede. The summit lacks greens, but Forty Niner, Upper KA, Sunset 71, and Pike are all great trails. Expert's won't want to miss Upper Giant Killer. The lift ticket prices are also lower than those at Killington.
In some aspects, however, Pico is not as good as Killington. It dosen't open until the middle of the season, and it's not nearly as big. If you're a good navigator and are able to handle more crowds, Killington is reccomended. Killington also features more of those famous runs, like Superstar and Outer Limits. Overall however, Pico is lots of fun.
