Note: The Kolob Terrace Road that leads to both entry points of the Left Fork (Subway) will be undergoing major reconstruction from March through the end of October. Three-hour blocks of closures will begin March 2, 2015. Plan accordingly.
Kolob Terrace Road Construction Schedule.
There are two ways to explore The Subway (the Left Fork of North Creek). Permits are required regardless of the direction of travel. Both trips involve extensive route finding. Visitors are encouraged to do the trip with an experienced hiker of The Subway or obtain a detailed route description. The Subway is a day-use area only.
From the Bottom Up
This is a strenuous 9-mile round-trip hike through the Left Fork of North Creek that requires route finding, creek crossing, and scrambling over boulders. This hike begins and ends at the Left Fork Trailhead on the Kolob Terrace Road.
From the Top Down
This is a strenuous 9.5-mile hike that requires rappelling skills, 60 feet of rope, and extensive route finding experience. The route also requires swimming through several deep pools of very cold debris-filled water. The trail begins at the Wildcat Canyon Trailhead and ends at the Left Fork Trailhead. Both trailheads are located on the Kolob Terrace Road.
