Visitors from other nations, including China, India, Pakistan and Taiwan, need visas. Best to check. WHAT TO WEAR Light casual clothes are recommended for the trek due to hot, humid weather around Pinatubo. Shorts are preferable as there are many stream crossings. A heavy load will really slow you down.
Public sanitation is a problem in many rural areas.
Drink only bottled, boiled or treated water. Guides with first-aid training are usually provided in a tour package. The plains, covered with gray ash that reflects sunlight, can make a warm day hotter. Bring plenty of bottled water. Since fine dust can seep in and cause discomfort, some tour agencies provide heavy-duty masking tape to wrap around the ends of socks or shoes.
