If you are on the way to Meinong from Tainan, this geopark off Hwy 28 in Tianliao will give you a taste of a very different landscape. The strange-looking badlands reminiscent of the moon's surface may make you wish you'd paid attention in geography class.
It's especially worth a visit if you're breaking for lunch – there are many local chicken restaurants nearby. Red bus 70 leaves from Gangshan South MRT Station in Kaohsiung six times a day between 8am and 6pm for Moon World. The last bus back is at 7.40pm.
