For those fond of the great outdoors, Taiwan has developed a network of regional hiking and bicycle trails, which continue to be expanded. Railway tours offer leisurely journeys through the countryside, and include Hsinchu County's Neiwan Line, which takes tourists to experience Hakka culture and cuisine; the Jiji Line in Nantou County; and the 72-kilometer Alishan mountain railway. Adventure sports such as surfing, scuba diving, sailboarding, paragliding, and bungee jumping are gaining popularity throughout the island. Taiwan also has one of the highest concentrations of hot springs in the world. These include one of the world's three seawater hot springs, the Jhaori Hot Spring on Green Island, and a type of muddy hot spring at Guanzihling of which also only three are known to exist globally.
For those who enjoy shopping, bustling night markets bedeck the streets in many of Taiwan's cities and towns, at which snacks, local specialties, clothes, and novelty items are on offer.
