Rock fall
In May 2004, the Hualien area experienced a strong earthquake resulting in the mountain-sides becoming unstable in many areas. Therefore, it is strongly advised not enter the gorge during or just after periods of prolonged heavy rainfall. There are several signs in English marking the more dangerous areas and hard hats are provided at the Tunnel of Nine Turns.
fees/permits
Entry to the park is free but if you want to go to some of the wilderness or into areas designated as Eco-protection areas or restricted mountain areas, you will need an entry permit. Be sure to apply for the permits early at least 1 week before as some permits are limited by a small number per day. Refer to the official Taroko National Park information website for application procedures: (http://www.taroko.gov.tw/...)
