The Best Places to Visit in Laos in August

August is the wettest month of the year in much of Laos. Heavy rains and intense downpours usually happen in the afternoon and don't last long. You can see the most impressive waterfalls during this month as there is abundant water. Here are some of the recommended places to visit if you go to Laos in August.

1. Mekong Riverside Park, Vientiane

 Mekong Riverside Park, Vientiane

If Vientiane is your first destination in Laos, then Mekong Riverside Park is a good place to relax and get a representative first impression of Laos. There, you can walk along the Mekong River and meet some local fishermen. You can also relax and drink some coffee. The Mekong riverside under a sunset is a beautiful setting for photography. And after dusk, you can walk around the busy night markets on both riverbanks. You could buy some local artifacts, Buddhist statues, sunglasses, or Laos t-shirts to bring home as Laos' souvenirs.

2. Mount Phousi, Luang Prabang

Mount Phousi, Luang Prabang

August is a good time to explore Laos' numerous natural attractions (if you avoid the cloudbursts). Mount Phousi is one you can't miss in Luang Prabang. As the highest point around Luang Prabang, you can get a spectacular 360-degree view of the surrounding landscape and Mekong River from the top. The sunset seen from the Mount Phousi is so beautiful that it attracts crowds of photographers. If you want to get a good spot, remember to go early in the afternoon. To climb up the mountain, you have to walk up only 355 well-paved steps, zigzagging up to the summit. It is advisable to wear comfortable walking shoes.

3. MandaLao Elephant Sanctuary, Luang Prabang

Vang Vieng Elephant Sanctuary

August is a good time to visit MandaLao Elephant Conservation in Luang Prabang, especially with kids. It is a good chance to interact with these lovely animals. Located on the banks of the river Nam Khan, the sanctuary itself is a beautiful nature park where you can stroll through the jungle in search of the elephants. You can bath and feed the elephants with your kids — all are allowed to participate. The sanctuary is famed for its ethical way of caring for the elephants. So, elephant riding, for example, is not allowed there.

4. Tham Nam Water Cave, Vang Vieng

Tham Nam Water Cave is a good place to go to avoid the summer heat of August and to explore Vang Vieng's famous underwater caves. The 500-meter-long underground boat ride can be an interesting adventure, as you glide across patches of pristine water and check out dark corners with your headlamp. The rain in August makes it an easy floating cruise. You would have to walk to explore the cave in dry season.

5. Buddha Park, Vientiane

Buddha Park, Vientiane

Buddha Park is always a place you shouldn't miss when leaving from Vientiane to your next Asian destination or going home. It is worth taking 3–4 hours to explore and see its more-than-200 religious statues scattered around the park. There you can climb up a giant pumpkin-shaped building, which is about 10 meters (33 feet) high, to get a view of its record-breaking largest Buddha sculpture. Besides the Buddha sculptures, there are beautiful gardens throughout the park where you can walk around peacefully or sit down and rest.

Crowding and Costs in August

Due to its humid and hot weather, few tourists choose August to visit Laos. So, you could enjoy more space and freedom when visiting Lao's top attractions. Heavy rains wash everything clean and fresh, which makes it a good time to explore its numerous natural highlights (in between downpours).

August is a good time to get the largest discounts on hotels and tour prices. Many branded hotels offer discounts for early-booking customers. So, August is also a good time to save some money or spend more days in Laos. Please contact us for August tour deals in Laos — we can do all the research and booking for your ideal trip.

What to Bring/Wear in August

It is quite hot and humid in August. Pack summer clothes and anything than can keep you cool and dry, such as t-shirts, shorts, light trousers, sun hats, sunglasses, and so on.

There are rainy hours almost every day in August in Laos. You are recommended to bring lightweight waterproof coats, waterproofed/quick-drying shoes, umbrellas, or anything that would keep you dry and comfortable.
