About Tham Chang Cave
Tham Chang Cave is very easy to reach from Vang Vieng town centre. You need to walk to the southern edge of the town and enter into Vangvieng Resort. As you enter the Vangvieng Resort there is an entrance gate where you will be charged 5,000 Lao Kip for passing through the resort.
It’s a short distance from the entrance to the Vangvieng Resort to the river. You then need to cross over the sturdy suspension bridge.
The bridge over to Tham Chang Cave is a tourist attraction in its own right. From the bridge you get excellent views up and down the Nam Song River.
Once you cross over the bridge turn left and walk about 200 metres along the path by the side of the river. Before you get to the entrance to the cave you come to a ‘blue lagoon’ with wooden bridges across. The water is a greenish blue colour from the minerals collecting in the water as it passes through the mountain before discharging into the pond below. The pool is a popular place for people to come and swim.
To reach Tham Chang Cave you need to ascend about 150 concrete steps, after paying another 15,000 Lao Kip at a ticket booth at the bottom of the stairs.
From the top of the staircase up to Tham Chang Cave you get a good view across rice fields hills to east of Vang Vieng.
Tham Chang Cave is spread over 2 levels with several separate chambers. It takes about 20 minutes to walk through the whole cave complex. The cave is fairly well lit and there are stairs with rails inside. It’s not dangerous and suitable for children over 8 years old.
Tham Chang Cave has some stalactites and stalagmites and some interesting colours on the walls from the effect of the minerals in the water dripping through the cave.
Tham Chang Cave is well worth visiting although there are better caves around Vang Vieng, but further away from the town centre. The inside of cave is noticeably cooler than the outside and a visit combining the cave with the blue lagoon and the viewpoint is a good way to spend a few hours.
