How to: Cross the Thailand Laos Border (The Ultimate Guide for USA & EU Citizens 2026)

In this guide, we’ll cover everything you need to know about crossing the Thailand Laos border as an American and/or EU citizen in 2026.

We opted to cross by land, but you can also take the slowboat from Thailand to Luang Prabang, crossing the border along the way. You can reserve this tour online here.

Here’s what I’ll cover in the guide:

1. Do US & EU Citizens need a visa to enter Laos and cross the Thailand Laos Border?
2. What Is the Most Popular Thailand Laos Border Crossing for Backpackers?
3. Getting from Chiang Rai to Chiang Khong

8. FAQs About Crossing the Thailand Laos Border

Do US & EU Citizens Need a Visa to Enter Laos?

Yes, both EU & USA passport holders need a tourist visa to enter Laos.

Visitors can get a 30 day tourism visa on arrival at the majority of major borders or can apply for a visa online prior to arrival at https://laoevisa.gov.la

We opted for the Visa on Arrival route and it went very smoothly, so that’s the option we’ll walk through in this guide.

I will say that after going through the whole process we did learn that it’s ~$5 cheaper to apply online before arriving so if you’re in a really tight spot cash wise it might be a good idea to apply ahead of time – $5 is dinner in Laos after all!

What Is the Most Popular Thailand Laos Border Crossing for Backpackers?

The most popular backpacker border crossing is in the north — the Fourth Thai-Lao friendship bridge from Chiang Kong district in Chiang Rai province (Thailand) to Houayxay district in Bokeo province (Laos).

This crossing is especially popular because it’s the gateway to the famous slowboat route from Houayxay to Luang Prabang — one of the classic Southeast Asia backpacking experiences.

As mentioned above, you can purchase a tour to take you from Thailand to Laos on the slowboat, crossing the border along the way, but purchasing that tour doesn’t mean that you get on the slowboat any earlier than somebody who opts to cross the border and then hop on the slowboat — you’re essentially just purchasing the bus from wherever in Thailand to the border crossing, help at the border, and then you hop on the slowboat in Houayxay, the same as everyone else.

Other popular crossings are:

• Nong Khai → Vientiane (central Thailand to central Laos)
• Chong Mek → Pakse (southern Thailand to southern Laos)

The night before we crossed, we stayed in Chiang Rai as from there it’s very easy to catch a cheap local bus to Chiang Kong and cross the friendship bridge all in the same day.

As a side note: one night in Chiang Rai felt like the perfect amount of time for us. Unless you’re really into temple hopping or museums, we personally found there wasn’t a huge amount to do beyond the main sights.

Getting From Chiang Rai to Chiang Khong

Assuming you’re crossing via the fourth friendship bridge, you’ll need to get to Chiang Khong. Buses from Chiang Rai to Chiang Kong leave from Chiang Rai Bus Terminal 1, directly across from the entrance to the Chiang Rai Night Bazaar.

For us, that meant waiting until 11:30am despite arriving early for the supposed 10am departure. Not exactly shocking — this is Southeast Asia after all and we just headed to 7-eleven for coffee and snacks while we waited.

Our biggest recommendation here is to arrive early in the morning and speak directly with the staff at the ticket desk. They’ll point you toward the correct Chiang Khong bus and give you the most accurate departure time possible. Give yourself loads of time to navigate these ambiguous bus schedules.

You pay for the bus in cash once you board. In February 2026, tickets cost us around 140 Thai baht (just over $4 USD).

The journey overall was ~2.5 hours with minimal traffic, and dropped us right at the Thai border. Beware that the bus was full and there was no AC which honestly wasn’t as bad as it sounds as all the windows were open and there were some fans.

Once you arrive at the Thai border you can immediately start the crossing. See section “Step by Step Thailand to Laos Border Process” below.

Laos Visa on Arrival for US & EU Citizens

The Laos Visa on Arrival is available at most major land border crossings, including all of the popular backpacker crossings listed above. It’s a straightforward process for both US and EU passport holders and allows you to stay in Laos for up to 30 days for tourism purposes with the opportunity to extend it only once.

At the time of writing, the visa costs around $43 USD per person. This includes the visa itself, a processing fee, and a small tourism fee. Keep in mind that this does not include transport costs — such as getting to the Thai border, crossing the Friendship Bridge via shuttle, or transport from the Laos side to your accommodation after arrival. We’ll cover those extra costs further below.

Border Crossing Checklist

At the border, you will need:

• A passport that is valid for at least 6 months from the date of arrival
• Crisp US Dollars to pay for the visa ($40 per person)*
• Thai baht (~300 THB total per person) to pay for:
  • The shuttle bus to cross the friendship bridge
  • The “visa fee” for processing
  • The “tourism fee” upon arrival into Laos
  • The taxi from Laos border to Houayxay once you arrive
• Two passport-sized photos (4x6cm) taken within the last 6 months
• Know the address of your accommodation for at least the first night in Laos

Step-by-Step Thailand to Laos Border Process

1. Once you arrive at the Chiang Kong border, pass through customs, bags are checked and you’re “stamped out” of Thailand.
2. At this point, buy the shuttle bus tickets that takes you across the friendship bridge to the Laos border. It costs 30 baht per person. If you need to buy USD this is also your chance at the same ticket counter but as mentioned avoid if possible as you get a bad exchange rate.
3. Hop on the bus, say byyyee to Thailand and Hellloo Laos! Enjoy seeing the flags change from Thailand to Laos on the bridge as you cross. The bus takes 7-10 minutes.
4. Arrive in Laos and follow the “Visa on Arrival” signs, you’ll be handed two forms – one to complete right there and then and the other you must hold onto to complete and present to immigration when you’re leaving Laos*
5. Give immigration officers the form, your passport, your passport pictures, and $40, extra crispy!
6. Before immigration gives you back your passport they’ll require a 40 baht per person “visa fee” for processing. Hence bring Thai baht to pay. Once you pay that, you’ll receive your passport back with the visa and stamp.
7. Upwards and onwards! Welcome to Laos! But alas, another fee awaits – 20 baht per person “tourism fee” right at the turnstile into Laos and then you’re freeeee

*When you’re filling out the form, you’ll also be asked to state how long you plan to stay in Laos. We recommend writing 30 days even if you’re staying less as it offers flexibility.

Common Mistakes and Border Crossing Tips

I touched on these throughout but here’s a list all in one place that’s worth a quick read to avoid any delays.

• Check border crossing times. Borders may have different opening times as a result of a holiday or weekend and immigration may add extra fees for travellers choosing to cross on either a holiday or weekend – we avoid extra unnecessary fees at all costs!!
• Make sure to give yourself ample time to cross the border especially considering the border crossing opening times and (assuming you’re traveling from Chiang Rai) the bus journey from Chiang Rai to Chiang Kong (2.5-3hr journey)
• Make sure to double check that the border you will be crossing at offers Visa on Arrival. Similarly, if you opt for Visa prior to arrival, make sure to check that the border accepts eVisas
• Make sure your dollars are CRISPY — that is not folded, pristine if you will. They won’t accept them otherwise
• Don’t wait until the border to buy USDs to pay for the visa on arrival (like us) and furthermore don’t wait until Chiang Rai to do it! They were all sold out of USDs
• To avoid fees and hassle in general just get passport photos before the border. There are shops all over Chiang Rai that offer this service, they’re well accustomed to travellers making the trip
• Do save and bring extra Thai baht to the border for the shuttle bus, the processing fee, the tourism fee, and the songthaew to take you into Houayxay (~300 baht)
• Avoid opting to use your credit card to pay for any of this at all costs. You will be ripped off — be prepared, use cash.
• Do keep the second form that you receive at Laos immigration as you need to present it when leaving the country and you will be charged if you lose it and need a new one (it’s minimal but every penny counts!)
