Phnom Sampeau Bat Caves is a must-see destination when visiting Battambang, Cambodia. It is located at the base of the limestone mountain known as Phnom Sampeau, situated about 12-15 kilometers southwest of the city center. The site is famous for the incredible natural spectacle that occurs every evening: where millions of Wrinkled-lipped bats fly out of the cave simultaneously to begin their nightly hunt for food.

Phnom Sampeau mountain also holds significant historical and cultural importance. At the summit, you will find Wat Phnom Sampeau and a viewpoint offering vast vistas of the surrounding countryside. Furthermore, it is the location of the Killing Cave, a poignant memorial reminding visitors of the atrocities committed during the rule of the Khmer Rouge, who used this cave as a site for mass executions of thousands of people. The site offers a powerful blend of natural beauty and a somber historical lesson.

The moment tourists eagerly await is dusk (around sunset), which is when the bats begin their continuous exodus from the cave in a long stream lasting over 30 minutes. The movement of the bat colony appears like a dark cloud stretching across the air, creating a truly impressive and awe-inspiring experience of nature's power. The area around the cave base is often lively, with vendors selling snacks and drinks while visitors wait to watch this natural performance.

This location appeals to nature lovers interested in the ecology of bats—which are crucial for pest control in farmlands—as well as history enthusiasts who wish to learn about Cambodia's past. It is also an ideal spot for photographers seeking to capture this unique phenomenon and the beautiful sunset views.

Travel Tips

• It is best to arrive at the Phnom Sampeau area in the late afternoon (around 4:00 PM) to have time to visit the temple and the Killing Cave on the mountain summit first, before descending to the base to wait for the bats near sunset.

• The dry season (November - April) offers better weather and clearer views.

• Wear comfortable, suitable footwear for hiking if you plan to ascend to the top of Phnom Sampeau.

• The best viewing spot is at the base of the mountain near the cave entrance, but avoid standing directly under the mouth of the cave to avoid guano (bat droppings)
