No. 8 of Best Things to Do in Laos

Blue Lagoon

Blue Lagoon is nestled among the karst mountains and is an attraction that combines caving and water activities. Tham Poukham Cave is considered quite sacred by the locals. The main chamber has a skylight at the top, where sunlight pours down, illuminating a Thai-style bronze reclining Buddha. Locals often come here to offer incense and pray. Several deep tunnels branch off from the main chamber, leading deep into the heart of the mountain, where stalactites and stalagmites stand in the darkness. The cave entrance is located on a limestone cliff halfway up the mountain, requiring a climb along a steep path. Fortunately, there are handrails on the steeper sections. After working up a sweat from the climb, it is the perfect time to cool off in the lagoon at the foot of the mountain. The Blue Lagoon is formed by water flowing out of the cave. The water is clear and deep blue, with schools of fish visible to the naked eye. The water temperature is cool year-round, making it very refreshing to jump in. Swing ropes hang from the large trees by the lake, and there is a diving platform nearby where you can swing out to the middle of the lake before letting go to enter the water. Some people also zip-line over the lake, causing those in the water to look up. There are several blue lagoons around Vang Vieng. This one is more popular because Tham Poukham Cave and the lagoon are in the same location. The water appears even bluer during the dry season, making it perfect for combining hiking, caving, and water activities into one itinerary.Vang Vieng · 5.8 km from downtown

it’s extremely fun activity but also has to be very careful as the current flow of the river rainy season is high.

A beautiful scenery on my early biking tour to the three blue lagoons, cave Phu kham, Blue Spring and Patong cave! Cycling here is extremely difficult because it was foggy, dry and no wind! I’m glad I still managed to do it and 11 miles is not bad! 😍

Vang Vieng is the capital of outdoor sports, and hot air ballooning is one of the must-do activities. We booked Impression Travel, and the cost was 680 RMB per person (one-third the price in Turkey). They picked us up from the hotel around 4 PM, and the flight time was about 45 minutes. There are two time slots a day: watching the sunrise in the morning and the sunset in the evening. It was a wonderful experience.

One of the best caves I have been to, it’s massive in the cave and need a light, I used my phone light and that was fine, but for KIP 10,000 you can hire a head torch. It’s in the same place as the Blue Lagoon 1 so you can do both for KIP 20,000.

ถ้ำจัง อยู่ไม่ไกลจากตัวเมืองวังเวียงมากนัก ตอนแรกพวกเราคิดว่าคงชิลๆแหละไม่น่าเหนื่อย แต่มาถึงแล้วต้องเดินขึ้นบันไดอีก 147 ที่ชันกว่าจะถึงด้านบน ในถ้ำจะติดไฟไว้เพื่อให้เห็นความสวยงามของหินงอกหินย้อย พวกเราไม่อยากออกจากถ้ำเลยเพราะด้านในเย็นเหมือนติดแอร์ไว้ 555 ด้านล่างของถ้ำจังจะมีบ่อน้ำเล็กๆธรรมชาติที่ใสมากๆ สามารถลงเล่นได้

The weather is good. It's better to go during the rainy season. Blue Lagoon 1 has very clear water. The entrance fee is not expensive and it's not far from Vientiane. It takes about 2 hours to drive there.

It is a very beautiful place. The atmosphere is shady and suitable for relaxation. There are many interesting things. The way up is very brutal, but the view is worth it.
