The Subway in Zion National Park is guaranteed to be one of the most unique, magnificent locations you will ever hike. This adventure describes the lower section of the route. The upper section requires ropes and rappelling skills, while this lower leg is a straightforward hike up the riverbed.

Begin your 6.5-mile hike at the Left Fork Trailhead off of Kolob Terrace Road. After a half mile, you will make a steep, 400-foot descent down the canyon to the riverbed. When you reach the bottom, note the exit sign, because it is easy to miss on your way back. From here, you will alternate between hiking trails and the river itself. Normally, the river is not very deep, but expect to get your feet wet. After about 2 miles, the trail enters the type of terrain that inspired the route's name, and you will see incredible erosion patterns in the rock. Eventually you will meet up with the lower subway, the stopping point if you are hiking without gear. You may be able to climb a bit further, but take caution. When you are finished enjoying this unique area, begin retracing your steps to the exit sign and trailhead.

Note that permits are required to hike this area. Reserve one early, because they are very limited. Always watch the weather and be aware of flash floods. Also, this hike can be very hot in the summer.
