Tam Coc has long become an ideal destination for all visitors to Ninh Binh. Tam Coc means three caves which were made due to the transformation of geology, seawater and rainwater that have worn cliffs in a long period of millions of years. Known as "Ha Long Bay on land", Tam Coc can only be reached by boats rowed along a meandering river which makes it way through three caves before unveiling a secluded watery valley.

Tam Coc consists of the Hang Ca, Hang Hai and Hang Ba grottoes which are adorned with beautiful stalactites and stalagmites of different shapes and colors sparkling like gemstones.

The first cave the tourists reach is called Ca cave which is located at the foot of a big mountain that crosses over Ngo Dong River. It is called Ca cave, as it is the first cave and also the longest and broadest cave of Tam Coc. If visiting the cave in the morning, you can see that a cliff at the entrance to the cave is sparkling and colorfully reflected by water surface when the sunshine passes by. When the tourist boat goes inside the cave, the atmosphere is very cool; the bowels of the cave are widely opened with sparkling stalactites dripping water to the river. The sound of water lapping to the boat sides and the sound of rowing boat make a clear and miraculous sound. As the cave is relatively long, you will have a feeling that the time is passing by more slowly with only some flickering light rays from the end of the cave gate.

Getting out of Ca cave, the tourist boat glides on shadows of mountain and clouds. In the distance, on the right, there is an impressive range of mountains with many big stones heaped together. The stones have been eroded by seawater for millions of years that creating regular long and straight lines. Continuing the way, we will see the Ham Rong Mountain and the Kim Quy Mountain with the image of grazing goats and ancient cycad trees.

Meandering partly along the river, getting access to Hai Cave (the second cave); tourists seem to be lost in the heaven because of the never- ending stretching lotus ponds with their specific perfume, and beautiful picture of mountain, river and water. Hai Cave rests under shadows of trees; the cave is 60 meters long and 18 meters wide; it is also situated at the foot of a mountain that crosses over Ngo Dong River. From the entrance to the ceiling of the cave, there are many stalactites with different shapes. When we are rowing our boats in the cave, we have the feeling of rowing among clouds of stalactites silhouetted against the water. The stalactites project down to the river from the ceiling of the cave so low that tourists can touch them.

Getting out of Hai Cave, the scenery is very imposing with mountains surrounding a part of Ngo Dong River which meanders through green rice seeding fields. The river between Hai Cave and Ba Cave is rather short; only around 100 meters. Therefore, when we have just got out of Hai Cave we can see Ba cave (the third cave) at the corner of the river. In the mountain, on the right hand there is a big cave; it is Bat Cave (Doi Cave) where flocks of bats live. There is another cave on the left, which has a big stone standing next to the entrance. The stone has the shape of a maiden girl sitting cross-legged, enjoying the view of tourists bobbing on boats in the river. Ba Cave appears with an entrance like a cross-fracture of the mountain, it is the smallest of the 3 caves but it is the coolest and has a pleasant breeze. The ceiling of Ba cave is low, the reflected light make tourist feel like heaven.

Say goodbye to Ba Cave, tourists can go ashore to relax, enjoy the scenery of mountains and valleys and from a far distance, and aroma of lotus ponds.
