Taiwan is covered in hot springs. There are famous ones like Beitou, Jinshan and Wulai, but there are also many “wild” ones. Generally the wild ones are a bit more off the beaten track, and are almost always quite difficult to get to. The biggest problem getting to them isn’t the drive or the hike, it’s finding good directions (in English or Chinese). But then again, I guess if they were easy to get to or had good directions, there would be more people there and they wouldn’t be as interesting.
I recently went on a ride down the Northern Cross Island Highway 北橫 with some friends. The main goal of this particular trip was to find a remote, wild hot spring called the Siling Hot Springs 四稜温泉.
