Are National Parks and Reserves Safe?
Bali has only one major national park and reserve, West Bali National Park. It is considered safe, Only a small percentage of the total area of the park is open to visitors, and a guide recommended by the national park office is required to trek the official park trails. In the marine areas, chartered dive, snorkel, or boat trips must be taken with officially recognized operators. All visit is by permit, which is often included within the cost.
While visiting the park, as long as you stay within the official limits and follow instructions from your guide or tour operator, your visit should be safe and uneventful. Remember to stay hydrated, and protect yourself against excessive sun exposure and mosquitos.
