The Best Places to Visit in Laos in September
September is a good time to visit Laos' picturesque landscapes and numerous waterfalls, as the heavy downpours make everything fresh and full of life, and the plants lush and green. The waterfalls are at their best views, and they are good places to avoid the summer heat. Here are some of the best places to visit in Laos in September…
1. The Great Sacred Stupa (Pha That Luang), Vientiane
As the capital city of Laos, Vientiane is rich in historical and sacred sites, including gorgeous Buddhist temples, pagodas, and quaint buildings. The sacred site of Pha That Luang ('The Great Stupa') is among the most visited temples in Vientiane. It was said that the Pha That Luang has more than 2,500 years of history. The 45-meter-high (150-foot-high) pyramid-like stupa has a main spire pointing into the sky and 30 smaller pagodas surrounding it. The best time to visit the Great Sacred Stupa is in a late afternoon, when you can stay for a spectacular sunset view of the kind that attracts photographers from home and abroad.
2. Kuang Si Waterfalls, Luang Prabang
September is the best time to visit waterfalls in Laos as the steadily increasing downpours preceding September bring them to their best appearance and highest flow. Kuang Si Waterfall is the most-visited cascade in Laos. It is located south of Luang Prabang, from which you can take a tuk tuk to get there. The waterfall is famous for tumbling down over a steep hillside with over 60 meters (200 feet) of descent through various cascades. You can explore some beautiful villages and meet local farmers around the Kuang Si area. Or you could take a boat tour, cruising downstream on the Mekong River, which is a highlight of many a Laos trip.
3. MandaLao Elephant Sanctuary, Luang Prabang
September is a good time to visit one of Laos' numerous elephant nature parks, as the heavy rains wash everything clean and the plants are lush and green then. MandaLao Elephant Conservation is the most recommended elephant nature park in Luang Prabang, and in all of Laos. There, you can interact with the lovely elephants, and your kids are allowed to as well. Wander through the jungles and forests, and you may be able to meet some of the elephants all by yourself. Bathing and feeding the elephants are activities that you could do in the park.
4. Nam Xay Viewpoint, Vang Vieng
As one of the most popular travel destinations in Laos, Vang Vieng is famous for its great mountain views and countryside landscapes. Nam Xay Viewpoint in Vang Vieng is the one spot you can't miss. Located on the top of a steep mountain, the viewpoint is the best place you can go for a spectacular bird's-eye view of the natural sights of Vang Vieng. You can also walk among the rice paddies, or visit a local famer's house to experience Laotian rural life.
5. Mekong Riverside Park and Night Market, Vientiane
If Vientiane is your exit city from Laos, then Mekong Riverside Park could be a good place to rest and buy some souvenirs and gifts to bring home. There are many nice coffee shops where you can sit back and sample locally-grown coffee on an afternoon. Many photographers go there to shoot the Mekong riverside under a sunset. The busy night markets, which begin after sundown, are the best places to buy some local artifacts, Buddhist statues, sunglasses, Laos t-shirts, etc.
Crowding and Costs in September
September is in the low season for travel in Laos, so you don't need to worry about tourist crowds in September. You can enjoy much more freedom to take photos in the most visited attractions in a month when Laos' natural landscapes and waterfalls are at their best.
Also, you can get good discounts on branded hotels and tour prices in September. Many branded hotels do increase their prices, though, later in September as the rainy season wanes and the high season approaches. For the best September deals, book your hotels or tour package well in advance (around 6 months to a year). Contact us for more on tour deals in Laos — we can do all the research and booking for your ideal trip.
What to Bring/Wear in September
It is ok to pack summer clothes in September as the weather is hot or warm at night. Popular clothes include t-shirts, shorts, light trousers, caps, sunglasses, and so on.
There are downpours and heavy rains, often in the afternoon, in September in Laos. So, if you are going out, especially in the afternoon, you are recommended to bring waterproof coats, quick-drying or rain-resistant footwear, umbrellas, or anything else that keep you dry and comfortable.

Bangkok and Chiang Mai
In Bangkok, our guide Ann and driver "Mr. Ot" (I don't know how to spell his name) were very friendly and professional. You simply can't underestimate the value of having an English speaking guide to show you around, and a driver with a comfortable, sizeable, air-conditioned van take you from place to place. Ann taught us so much about Thailand's history, food, and religion. Mr. Ot always opened our door with a smile, and had cool towels and ice-cold bottled water for us. More

Excellent guide in Siem Reap
Our recent time spent in Siem Reap was made even more memorable by our expert guide, Som Piseth. Som was knowledgeable, attentive, flexible and super helpful - we learnt so much about Siem Reap and Cambodia in our 3 days with him. His English was excellent and his knowledge of, and pride in, his country was outstanding. We would highly recommend Som for anyone wanting an excellent guide in Siem Reap! More
