South Twin Mountain Trail Maps - Directions from the parking lot to the summit Top

The map below shows how to get to the summit of South Twin Mountain as well as North Twin Mountain.

Begin at the North Twin parking lot at the end of Haystack Road. Hike up the North Twin Trail for 4.2 miles where you will reach the summit of North Twin Mountain. There are 3 river crossings within the first 2 miles of this hike, so be prepared. If the water level is high, it makes it really difficult to hop from rock to rock while crossing the river. There are no bridges crossing Little River.

To continue over to South Twin Mountain, continue hiking along the same trail, that changes from North Twin Trail to North Twin Spur. You will reach the summit after 1.2 miles. To get back to the parking lot, retrace your steps for 5.5 miles.
