The fusion zones are trails through the woods where the brush has been cleared out but the trees have been left alone. As with all trails at Killington, the fusion zones are also rated for difficulty, a combination of steepness of the slope and tightness of the trees. Let's take you through the six mountains if you look at the map from left to right. Sunrise Mountain has a summit of just under twenty-five hundred feet. It is the smallest of the mountains and is one of the less popular of the mountains.
Sunrise tends to be less crowded than some of the other mountains and is more of a novice area.
In order to get to Sunrise you have to suffer through some walking on flat trails. If you are looking for quiet, Sunrise is the place to go. Bear Mountain is definitely the bear of the six. It will growl at you and you just have to challenge it. The Bear stands at 3,295 feet tall.
