The good thing about Bannoe is that the lifts actually cover a small part of the area, so there's a lot of natural forest terrain. However, as there's not too much snow, you'll find lots of rocks on the way, so it's not really a good place to go off-piste. You might want to go along the routes, which are yet to be built (marked dots on the piste map), as there is more snow there.
There is no terrain park, however, the halfpipe at the bottom of the mountain is a good place to start. There are also a few places at the top of the mountain, especially along the 3rd piste, where there's a lot of trees and varied landscape to play with.
The runs tend to be well looked after, so unless there's too many skiers, carvers will like this place for a day or two. The runs are cut through the forest, and the width is about 30-60 meters.
Will be very satisfied, as most of the piste runs are quite easy and not steep. There is also a 300-meter slope for beginners at the bottom of the mountain. but it's better to get on top of the mountain, where there's more snow and the runs are softer.
