Taiwan, situated in subtropical and tropical Asia, is an island of 36,000 km2 and with coastal line stretching 1,100 km. The highest mountain, Yushan, is about 4,000 m. Due to the high elevation difference, the climates are very different along the altitudinal gradient, producing a diverse and abundant wild fauna and flora. Geologically speaking, since Taiwan is a relatively young island, volcanic activity, gorge cleaving and rock formation are wonders still in action today. The Chinese culture that has been well preserved on the island has also intrigued its foreign visitors.
