Green Mountain Summit Loop

The terrain on this 9-mile loop is quite varied. You'll find enjoyable rolling singletrack on the western side, which is suitable for beginners. However, as you approach the 'Florida parking' area, the trail turns sharply uphill into a steep climb. Along the ridge past the radio tower, it widens to a smoother, almost dirt road-like path. The descent from the summit is fairly steep and winding, with some loose rocks and occasional small, avoidable muddy spots.
