The Lü-shui Wen-shan Trail is cuts through the mountains between the Wen-shan Hotsprings and the Geological Exhibition Hall in Lü-shui. Along the 5.5 km trail you get nice views of the surrounding mountains, the Li-wu River Vally, and the village of Tian-xiang. This is a fairly rigorous 4-5 hour hike. Many people begin this hike at the Lü-shui Trailhead (see waypoint). If you start, as we did at the suggestion of some locals, at the Wen-shan Hanging Bridge Trailhead (see waypoint), many of the valley views are better enjoyed as they are in front of you as you hike rather than having to look over your shoulder going the other direction. Some sections of this trail require scrambling up/down/over a lot of steps/rocks/roots with some ropes/chains to help you. We saw monkeys and heard several barking deer along the trail. To return to your car/motorcyle/bicycle parked at the other end of the trail after you complete this hike you can walk back along highway #8 (a nice stroll along the Li-wu River when the cars/buses are scarce) or catch an empty taxi going your direction.
The cache container is a black plastic bottle (a skinny pop-can size/shape) and contains a pencil and a log sheet. You do not need to climb up/down any steep slopes to get to this cache. If you can't find the cache container, you can also log a find by attaching a pic of yourself holding your GPS device with the bridge in the background.
