The Skyline Trail is a great singletrack trail that traverses the mountains above Big Bear Lake and the Snow Summit Ski Resort. Beginning at the end of Dogwood Drive, where it turns to dirt, the trail immediately begins climbing the mountainside and continues to do so for 1.8 miles while often utilizing switchbacks. After another short climb the trail arrives at the top of Snow Summit before switchbacking as the trail rolls up and down alongside the side of the mountain. After being on trail for 10.2 miles you'll reach a big descent that will end with a slight uphill that exists just before the end of the trail. The trail ends as it reaches Metcalf Creek, from which point you can follow service roads back to Big Bear Lake.
