Things to Do at Tham Phu Kham Cave

Tham Phu Kham Cave, also known as the Blue Lagoon Cave, is one of Vang Vieng's most spectacular natural attractions located about 7 kilometers north of the town center. This limestone cave system features stunning stalactite and stalagmite formations, underground chambers, and a sacred bronze reclining Buddha statue that has become an iconic symbol of the site. The cave extends deep into the mountainside, offering visitors a mystical underground adventure through narrow passages and expansive caverns. What makes Tham Phu Kham particularly special is its combination with the famous Blue Lagoon (Nam Xay) at its base. After exploring the cave's cool, dark chambers, visitors can refresh themselves in the crystal-clear turquoise waters of the lagoon, which maintains a constant temperature year-round. The site has become a pilgrimage destination for locals who come to pay respects to the Buddha statue, while also serving as one of Vang Vieng's premier tourist attractions for those seeking both cultural significance and natural beauty.

Tham Phu Kham Cave is located 7 kilometers north of Vang Vieng town center. The most popular way to reach it is by renting a bicycle (20,000-30,000 LAK per day) or motorbike (80,000-100,000 LAK per day) and following the well-marked road signs. The journey takes about 20-30 minutes by motorbike or 45-60 minutes by bicycle through scenic countryside. Alternatively, you can join a organized tour, hire a tuk-tuk for the day (around 200,000 LAK), or take a songthaew (shared pickup truck) from the main road. The final approach involves a short walk from the parking area to the cave entrance.
