Hike Around and then Cruise Down This Spectacular Gorge on a Bike
A fellow named Rihang owns a guest house near the bottom of the gorge that runs a fantastic program for visitors: Rihang will rent you a room, help you apply for hiking permits (when necessary), and then will drive you to the trailhead of your hike in the morning. The really good part comes last. He gives you a key, and locks up a bike for at the end of the trail. There is no better way to enjoy the splendor of this enormous gorge than to spend a day hiking it and top it off with a easy bicycle cruise down through it. Read all about it here.
It's brilliant. No pedalling required (well, maybe just a bit at the end).
