Tam Coc, literally "three caves or three grottoes", consists of three natural caves — Hang Ca, Hang Hai, and Hang Ba — on the Ngo Đong River. Tourists are taken in small boats along the river from the village of Van Lam, through rice fields and limestone karsts, through the caves, and back. Local women serve as guides and attempt to sell embroidered goods to their passengers.

Hang Ca
Hang Ca means 'First Cave', also the largest cave with 127m in length and an entrance 20m high. When the boat enters the cave, you'll a cool, refreshing atmosphere here and also can see beautiful karstic formations.

Hang Hai
Hang Hai is the Second Cave, also the second largest in size with just 60m long. The second cave is about 1 kilometer from the First Cave. The second cave is known for its gorgeous ceiling.


Hang Ba
Lying just right next to Hang Hai, Hang Ba (Third Cave) is only 50m in length, much lower than the other two. The cave's ceiling looks like a little dome made of limestone.
