Crossing the Border from Thailand to Laos

Getting to Laos is half the fun. The southeast Asian country was virtually closed off to tourism until the late 90s, and is just opening to the world. To cross into Laos, we traveled from Thailand by plane, bus, taxi, foot, and finally, a 2-day slow boat cruise on the Mekong to Luang Prabang, Laos. The border crossing at Huay Xai, Laos was the most laid back I’ve ever been to – read on to hear why!

Traveling to Laos from Thailand

I knew I wanted the experience of traveling overland to Laos from Thailand, to move at a different pace. To see the scenery and experience all the jostling and bumps of overland travel. The plan was to take our time getting to Laos, a country most often referred to as “forgotten” or “untouched.” Everything I had read about Laos said that things there move at a different pace – everything slows waaay down. So, we would too: we traveled to Laos from Thailand by bus, taxi, foot, and finally, a two-day Mekong slow boat trip to Luang Prabang, Laos.

On my two recent trips through southeast Asia, the cheapest and most convenient flights from Europe were to Thailand: Bangkok, Phuket, and Chiang Mai are the top destinations. From any of these cities, there are plenty of cheap AirAsia flights throughout the region – to popular destinations like Vietnam, China, and Malaysia, but also increasingly to less-touristed places in Cambodia, Myanmar, and even Laos. So if traveling by bus and boat isn’t your thing, or if you’re pressed for time, there are good options for flights to Laos, too.

Border Crossings to Laos from Thailand

There are several overland border crossings from Thailand to Laos, listed here from north to south:

  • Chiang Khong, Thailand, to Huay Xai, Laos. This is the one we took, and I’ll describe the experience in more detail below. The Thai-Lao border crossing at Chiang Khong-Huay Xai is only about five hours by bus from Chiang Mai, Thailand’s second largest city, and public transport is easy, cheap, and plentiful to arrange directly to the Thai border town of Chiang Khong. After crossing to Huay Xai, Laos from Chiang Khong, most travelers take a slow boat trip on the Mekong to Luang Prabang. The slow boat ride was the highlight of my trip, and is an atmospheric way to begin (or end) any trip to Laos!

  • Nakaxeng, Thailand to Kaenthao, Laos. This Thai-Lao border crossing is south of Chiang Khong – Huay Xai and is not as well served by Thai public transport. It’s also not on the Mekong river, making onward travel to Luang Prabang, Laos more difficult than it is in Chiang Khong – Huay Xai.
  • Nong Khai, Thailand, to Vientiane, Laos. This Thai-Lao border crossing makes sense if you want to begin your trip in the Laotian capital of Vientiane, which roughly sits in the middle of the country. But Laos is a long and skinny country, and to me, it makes the most sense to start in the north or south and work your way up or down to avoid backtracking. This border crossing is not far from Udon Thani in Thailand, which is a big city well connected to domestic destinations in Thailand only about an hour from the Lao border by bus.
  • Nakon Phanom, Thailand to Thakhaek, Laos.  A Thai-Lao border crossing towards the top of southern Laos. Not very convenient to tourist attractions in Laos or Thailand.
  • Mukdaharn, Thailand to Savannakhet, Laos. About two hours south of Nakon Phanom, Thailand  – Thakhaek, Laos. Also not as convenient to tourist attractions as other Thai-Lao border crossings.
  • Chong Mek, Thailand to Vangtao, Laos. Transportation to the regional hub of Ubon Ratchathani on the Thai side makes this crossing convenient to get to. On the Laotian side, Vangtao is only about 40 minutes from Pakse, the regional capital of Lao’ fabled Champasak province. Pakse is the gateway to the attractions of southern Laos, including motorbike trips of the Bolaven Plateau for its coffee plantations and incredible waterfalls, the UNESCO world heritage temple ruins at Vat Phou, and further south, the 4000 Islands. Pakse is also well served by overnight buses from/to the capital of Vientiane. Lastly, onward bus travel to Cambodia (Siem Reap and Phnom Penh) also departs from Pakse/4000 Islands.

There are other land borders between Thailand and Laos, but they do not issue visas on arrival for foreign nationals.

Visa on Arrival in Laos

For tourists from most countries, the Lao visa is available upon arrival at the land borders mentioned above. The Lao visa on arrival is also available at all international airports in Laos.

To obtain the 30-day tourist visa at a Lao border crossing, you need a completed application form, a blank page in your passport (with at least 6 months validity), two passport-size photographs, and the visa application fee, which needs to be paid in cash.

The visa fee is determined by your country of nationality, and most cost around $30. The fee can be paid in US dollars, Thai Baht, or Lao Kip. We paid in US dollars, since the equivalent fee in Thai Baht is heavily inflated and thus more expensive, and we did not yet have Laotian Kip. The same goes if you’re traveling to Cambodia, too, as you’ll have to pay for a visa at the Cambodian border in cash as well. (As a side note: the currency in Cambodia is effectively US dollars, which are dispensed from local ATM machines.)

It’s important to note that ATMs in Laos do not always accept foreign debit/credit cards and sometimes we had to look around for one that would take our card. Unlike neighboring Thailand or Cambodia, there was always a maximum withdrawal at ATMs in Laos of around $200, and a pretty hefty ATM fee of around $5-10, plus whatever your bank at home charges you for foreign transactions. In hindsight, bringing US dollars and exchanging them for Kip in Laos probably would have been cheaper than all the foreign transaction fees we ended up paying.

Traveling to Chiang Khong from Chiang Mai

Before leaving Chiang Mai, make sure to try it’s signature dish: Khao soi gai (Thai coconut curry noodles). It’s the ultimate Thai comfort food.

We took a minibus to the border town of Chiang Khong from the downtown Chiang Mai bus station. We had bought our tickets in Chiang Mai two days in advance, as we were there at Christmas, when things book up. The bus meanders through beautiful country roads as it chugs north to Chiang Rai. I’m prone to motion sickness, and I’m glad I took a pill beforehand.

The Thai are also very punctual and the bus departs on time, so it was a good thing we were there well before the scheduled departure. The bus driver gave us a pack of cookies and a bottle of water for the journey.

After about 3.5 hours, the bus made a short stop in Chiang Rai to drop off passengers and pick up new ones. Unfortunately, the bus stop is far from the White Temple, Chiang Rai’s biggest attraction, and the “layover” isn’t long enough to do much more than go to the bathroom and buy some snacks.

Try as I did, I couldn’t find a bus company that combined a visit to the White Temple in Chiang Rai on the way to Chiang Khong. If we had had more time, I would’ve taken the bus to Chiang Rai, and spent the day visiting the White Temple and the city. The next morning, or later that evening, we could’ve then taken another bus to the Thai-Lao border crossing town of Chiang Khong.

Is It Better to Stay in Chiang Khong or Huay Xai?

Border towns get a bad rep, but Chiang Khong is actually a lovely little town, and I wish we had planned another day or two there to just relax. The biggest attraction is the panoramic view of the Mekong, and a long promenade that stretches for miles, which gives the town a kind of European vibe. When we weren’t sitting on our balcony watching the river laze by in Chiang Khong, we were strolling down the river walk.

Chiang Khong is more than just a border town – it also seems to be a local vacation destination for northern Thais, and there are plenty of nice hotels and restaurants. But the best hotel, and best value for the money in Chiang Khong, has to be the Day Waterfront Hotel (the picture above was taken from our hotel balcony). The owners made us feel like family, and they helped arrange onward travel to the border and slow boats to Luang Prabang, Laos. It’s the kind of place where guests feel so at home that everyone ends up chatting like long-lost relatives, and you find yourself going out to dinner in Chiang Khong with other guests from the hotel.

In comparison to Chiang Khong, I wasn’t impressed by what I saw on the Lao side in Huay Xai on our way to the slow boat pier – Huay Xai is a gritty, unplanned, sprawling border town – and I’m glad we stayed in Chiang Khong.

I had been worried about missing the slow boat the next morning, but it’s not necessary to cross into Laos the night before onward travel. The Lao border station at Huay Xai isn’t crowded, even in the high season, and any of the slow boats departing for Luang Prabang know that passengers cross in the morning. Some slow boat companies in Huay Xai even send a representative to fetch their passengers at the Lao border crossing. So, I would recommend staying in Chiang Khong for a day (or two, or three).

Plus, staying in Chiang Khong overnight before crossing to Huay Xai has another benefit: the sun rises over the Laotian side of the Mekong, and the sunrise was incredible.

Crossing the Border from Chiang Khong to Huay Xai

The border crossing to Laos is actually about 10 kilometers south of the city of Chiang Khong. From our hotel, we took a taxi  (actually, it was an open-air pick-up truck outfitted with two facing benches, quite typical in Thailand) to Thai immigration, which is located before the friendship bridge over the Mekong.

After passing through Thai border control, we exited immigration and were directed on to a bus that drove us across the bridge into Laos. The bus ride was mandatory (they did not allow people to walk) but it cost under $1.

Once we reached the other side of the bridge, the bus dropped us off and we proceeded through Lao immigration and applied for our visa on arrival.

The process actually took about a half an hour – not because it was busy or bureaucratic, but because it was breakfast time. The official working the desk took our papers, looked at down at them, and then glanced longingly at his breakfast on the table. He then put the papers down, and joined his colleagues munching on noodles and fresh herbs. The work would have to wait.

We got our Lao visa on arrival about a half an hour later. I took it as a promising sign: the pace of life was already slowing down, and technically speaking, we weren’t even officially in Laos yet.

Instead of getting annoyed with the “delay,” we just went with the flow. We were in no rush. With our visas on arrival in hand, we had arrived. We were in Laos.

But the trip was just beginning. Up next was an unforgettable 2 day slow boat ride on the Mekong from Huay Xai to the ancient royal mountain city of Luang Prabang.
