The Tunnel Trail into the gorge is a .3 mile, difficult trail that takes users from the Visitor Center down into the gorge where they may see the tunnel from the observation platform or hike south along Stock Creek to the Carter family cabin. The trail is gravel, somewhat steep, and has a lot of switchbacks. Hikers should not assume that the short length of the trail makes it any easier. If you have any doubt about your ability to climb back out of the gorge, consider the chairlift as an alternative.
