Vail is a great place for people who already know how to ski or board. It has some green runs, but is mostly made up of blues and blacks. It also has a lot of options for bowl skiers! I don't often go to the back bowls, but they are pretty easy to get to.
Navigating the mountain in general is not too bad. If I do ski the bowls, I often ski in Game Creek Bowl, since it's on the front side of the mountain and I can still move around to other lifts pretty quickly. It even has a green run for those who don't ski blues and blacks, so you can stay in the bowl with friends and family. You can get there from the Wildwood Express Lift, which also has some nice runs.
One of my favorite chairs is Mountain Express Life. It is mainly blue runs, with a couple longer blacks and a green to the far left. It's a good place for people of all levels, because some of the blues are more easy, while others are more challenging and offer some moguls. Zot, a great black run, also is mixed in difficulty. It often has moguls along the entirety of the run, but sometimes the beginning is flatter. For those who fear nothing and love a challenge, it even has a cliff drop-off! I've never done it. If you do, be sure to give those watching from the chairlift a good show!
Another good chair is the Avanti Express Lift. It mainly has blues and blacks, and is a great lift to use to get to other areas. Before I end the day, I like to make my way over to Pride Express Lift. Here you can squeeze in some blues or greens before your final run to the bottom. This is good if you want to end in Lionshead Village. If you're looking to end in Vail Village, you can do so from Pride Express Lift, but it will involve long catwalks and greens. Another route is more enjoyable and easier on a snowboarder's calves.
Even if you're not a big skier or snowboarder, you can have a great time in Vail. There are lots of other things to do, and the villages are a lot of fun!
