The North Twin Trail takes you from the end of Haystack road to the summit of North Twin. Within the first couple miles, you will cross a river three times. This means you should be prepared if the rivers may be high, as passing can be very difficult during high water.
At the summit of North Twin, the trail switches to the North Twin Spur, which connects the summits of North and South Twin.
Haystack road can be closed sometimes. If this is the case, prepare to add 4.5 miles roundtrip to your hike.
