The Yen Cave is the second most popular cave however it is somewhat inaccessible to most tourists as it is near a military zone north of Starfish Beach. The Yen Cave is smaller than the Bat Cave however it does have stunning views of the Gulf of Thailand.
Good footwear and a flashlight are a must when exploring all the caves in Phu Quoc, and be aware of slippery paths, low ceilings, and a variety of snakes and spiders inhabiting these caves.
Chao Mountain Cave
The Chao Mountain (382 meters high) is located in the northern part of the Phu Quoc National Park. The area around the mountain is rich in flora and fauna as well as numerous caves. These caves are currently inaccessible to tourists at the moment however there are plans on making these caves into an ecotourism attraction. We will update this page as soon as we receive more information from the Vietnamese tourism officers.
