Sanmin Bat Cave(三民蝙蝠洞)


Popularity: 4962

Sunday: Open 24 hours a day


Stand on the wooden platform and have both waterfalls within reach.

God’s work: the crescent shape water cave.


The bat cave is located in a ravine north of Sanmin Village; it is a large natural rock cavern under a spring, so the cave is also known as the Shuilian (water curtain) Cave. Since the bat cave is still in its natural primitive condition, as well as being nearby a ravine, it has attracted a large number of bats to make it their home, hence the name "bat cave". Today, the bottom of the cave is covered with red soil, which is an accumulation of the guano left behind by the bats. One can just imagine the time when bats flourished here by the thousands, and it also adds to the mystery of the place.

At the end of Taoyuan Country Road 114, there is the entrance of the Bat Cave Trail. The trail is 600m in length, flat and paved with stone tiles. A 20-minute walk will take you to the bat cave. Following the trail down, the whole way is shaded and cool. You can enjoy the rich ecology along the way. If you get tired, you can rest on the wooden benches and enjoy the interesting tile patterns of bats on the ground.


Walk down the trail for about 444 meters and you will see the viewing platform in a spiral staircase design. Go up the winding staircase to enjoy a lovely view of the verdant mountains and forget about your troubles.

Follow the stairs down behind the pavilion next to the observation deck. Enjoy the view of the running Sanmin River along the way. On the wooden deck you can see the waterfall splashing down, creating a deep pool 10 meters in diameter. It’s a great spot in summer for cooling down in the heat.


The entrance of the bat cave is a semi circle hidden within the cliffs of the ravine. The entrance has a height of around 20 meters; inside the cave it is around 50 meters wide and 20 meters deep. Enter the cave sideways to discover that the interior of the cave is in a half-moon shape similar to an amphitheater. The interior space is unique and spacious, wide enough to fit a thousand people. As it is a giant natural cavern rarely found in Taiwan, it is a one-of-a-kind experience. Although the bats that once inhabited the cave have since moved elsewhere, the awe-inspiring sight of the deep cavern still attracts many visitors.
