Safety and Preparation

Taiwan’s mountains demand respect. The combination of altitude, rapid weather changes, steep terrain, and the possibility of typhoons creates genuine risks. Every year, hikers require rescue or, tragically, lose their lives on Taiwanese peaks. Proper preparation isn’t optional.

Permit systems exist for good reasons. For high-altitude trails and certain protected areas, permits serve multiple functions: limiting environmental impact, ensuring hikers have declared their plans for search-and-rescue purposes, and requiring proof of adequate preparation. Attempting to bypass permit systems is illegal and foolish - mountain patrols do check, and being caught can result in fines and bans from future applications.

Apply for permits well in advance through official channels. For Yushan and other popular Baiyue peaks, this may mean applying three to four months ahead during peak season. The application process typically requires uploading identification (passport for foreign nationals), providing detailed itineraries, and sometimes demonstrating mountaineering experience or insurance coverage.

Physical preparation should be specific to your objective. For easy suburban peaks, general fitness suffices. For medium-difficulty trails, you should be comfortable with sustained uphill hiking for several hours whilst carrying a daypack. For Baiyue peaks, train with loaded packs (10-15 kilograms), practice on similar vertical gains if possible, and consider your altitude response honestly. If you’ve never climbed above 3,000 metres, attempting Yushan as your first high-altitude experience presents unnecessary risk.

To check the difficulty and the status of a trail and the need of permits, please refer to the official website, which classifies the trails into Level 0 to 6, the higher the more difficult.

Equipment requirements vary by difficulty and season:

For easy trails: proper footwear with good grip (Taiwan’s stone steps become slippery when wet), water, sun protection, and basic first aid. The humidity means you’ll sweat extensively even on short hikes—bring more water than you think you’ll need.

For medium trails: add layers for changing conditions, rain gear (afternoon thunderstorms are common), navigation tools (mobile phone with downloaded offline maps at minimum), headlamp if you might be caught out after dark, and emergency supplies (whistle, emergency blanket, additional food and water).

For Baiyue peaks: comprehensive mountain gear including proper boots, layering systems for temperatures from subtropical heat to near-freezing conditions, waterproof jacket and trousers, sleeping bag and pad for hut stays, headlamp with spare batteries, comprehensive first aid kit, altitude medication if you’re susceptible, and three-season or four-season equipment depending on your timing. Winter ascents require additional specialist equipment.

Weather monitoring is crucial. Taiwan sits in a typhoon zone, and the season (roughly June through October) brings risks of powerful storms. Never ascend into the mountains when typhoon warnings are active—the winds and rainfall can be deadly even on well-maintained trails. Beyond typhoons, Taiwan’s mountains generate their own weather systems. Afternoon thunderstorms are common, particularly in summer. Clear mornings can deteriorate into clouds, rain, and lightning by early afternoon.

Check weather forecasts before departing and monitor conditions during your hike. The Central Weather Bureau provides mountain-specific forecasts. Many Taiwanese hikers use mobile apps that provide real-time weather data for specific peaks. If conditions deteriorate beyond your comfort level or equipment capabilities, retreat is always the correct decision.

Emergency procedures should be understood before you need them. Taiwan’s mountain rescue services are professional and responsive, but you must be able to contact them. Mobile phone coverage exists on many popular trails, particularly at higher elevations and ridgelines, though valleys may have no signal. The emergency number in Taiwan is 119 (fire and ambulance) or 110 (police). For mountain rescues, 119 is typically appropriate.

Inform someone of your detailed plans before departing. For Baiyue peaks, this is partly satisfied through the permit process, but additionally tell a friend, hotel staff, or hostel manager your expected return time and where you’re going. Carry identification at all times.

Hiking insurance is increasingly required for permit applications to major peaks. Even where not required, it’s prudent. Your standard travel insurance may not cover mountaineering above certain altitudes or in remote areas. Verify coverage or purchase specialist mountain insurance.
