Yes, unless you hold a passport from one of the following countries:
Brunei (14 days)
Indonesia
Laos
Malaysia
Philippines
Seychelles (14 days)
Singapore
Thailand (14 days)
Vietnam
Un tourist visa costs $30 and allows a 30-day stay, extendable by going to the immigration office. As it is basic to obtain, basically just the passport and filling out the documents + identity photo, many people simply do it on site upon arrival (Visa on arrival).
Be careful though, if you are Algerian, the visa must be obtained in advance, and for that, fortunately, there is an e-visa.
Getting an e-visa for Cambodia
The e-visa is a bit more expensive than the "one" arrival "On 36$. Just like a classic visa, you are issued with a residence permit valid for a defined period. (here, 30 days by default for a visa tourism). The only difference is that you will have this authorization beforehand, so it can avoid some inconvenience. bound at the land border crossing (see below the paragraph concerning scams)If you arrive by plane, it doesn't have much of an impact, but it's still a guarantee that you'll leave with a little more peace of mind.
The process remains quite simple, here are roughly the few steps to obtain the sesame, and first, connect to the official website of the Cambodian government. First, you can switch the site to French by clicking on the drop-down menu at the top.

The header should look like this.
Then there are a series of steps that you already know if you have ever had to do an e-visa:
- At the top of the menu, click on “Request”
- You will have a "captcha" to fill out (this is a security feature), simply retype the set of numbers and/or letters that you see (capital letters to be respected if necessary)
- Fill in the personal data + identity photo to be provided: fields marked with an asterisk * are mandatory
- Fill in your passport data, photocopy of the main page with your first and last names
- As you can see, it is necessary to know your arrival date, so if you are not sure, for example in long-distance travel mode, you might prefer a visa on arrival.
- Same remark knowing that you need to know your point of entry into the country, to be selected via the drop-down menu
- Please double check all the information entered before proceeding to the payment stage.
- Pay the $36 (which is equivalent to €30)

Once finished, you should receive an email summarizing your request and, most importantly, a reference number, to see where your request is at. To do this, when returning to the site, look in the menu for the option "Check and change".
Once the e-visa is ready, you will receive another email inviting you to download it. Knowing that it can be very quick since if a request is made in the morning, you can have confirmation the same day.
As is often the case with e-visas, hence the need to know your point of arrival beforehand, it can only be used via certain accesses:
- Phnom Penh International Airport
- Siem Reap International Airport
- Sihanoukville International Airport
- Cham Yeam (Koh Kong province, border with Thailand)
- Poi Pet (Banteay Meanchey province, most used, also bordering Thailand)
- Bavet (province of Svay Rieng, bordering Vietnam)

Border scams
We come to the touchy subject. Border scams. Arriving in Cambodia is unfortunately known for being particularly prone to ways of getting a few extra bucks out of you.
Mind you, I'm not complaining about the amounts involved, which are quite small, but a scam, whatever the amount, remains immoral and unacceptable, even in a poor country.
And it's even worse when it's the officials who are directly involved in it.
Crossing the border between Aranyaprathet and Poipet
In order not to overload this time, I wrote a dedicated article about crossing this border.

The border between Aranyaprathet (Thailand) and Poipet (Cambodia).
Crossing the border between Laos (4000 islands) and Cambodia (Trapaing Kriel)
So here we enter the corruption category level +2000. This border is terrible in the sense that it concerns both the Laotian side and the Cambodian side. Although, from experience of most passages, it is easier on the Laos side (because you come out of it) than on the Cambodian side.
And this corruption is organized at several levels since even the buses crossing the border are in cahoots. Drivers offering to take your passports and arrange visas for a fee 40$...
Is 10$ just to be able to sit on a bus… A bit expensive for a few minutes of service, even if I have no doubt that it suits a good number of tourists who are resistant to it.Directors (is not Cahuzac who wants).
To summarize, as explained so far, the Cambodian visa is normally 30$ point. But here, we're going to add a whole bunch of fees that come out of nowhere and have no official validity. To cite an example, you will typically be asked 35$ for the visa, as if the latter had mysteriously increased since the previous day when you had checked the information on the net.
Reaching the border from the 4 Islands
The first step is to reach the border. Many tourists do this in transit, taking a bus to their final destination, usually Siem Reap or Phnom Penh.
If you want to do everything independently, you will have to be patient. You can take a tuk tuk from Naka Sang, the village where the main pier for the 4 islands is located. It will take you the 000 km journey for 17 Kips (€100) and will drop you off 000 m from the Laotian border post, if you share it with several people, it's still reasonable.
Avoiding bribes at the border, possible?
And here the trouble begins. To leave Laos, you are asked 2$. The stamp is expensive…. If you refuse, you will be ignored and told that you are stuck in Laos.
In fact, if you stay patiently and regularly hand your passport to the customs officer with a smile, it usually ends up going through. You might first see one of those busloads of tourists pass by who will happily pay without asking any questions and with luck, you will pass right by, without paying.
On the Laos side, the advantage is that they remain relatively calm if you refuse to play their little game. It's just a psychological "war". The most important thing is not to lose your cool.
Then you cross the No Man's Land and arrive Cambodia side. There, we will pretend to have a medical check-up and you will be asked 2$ Moreover. Depending on the case, this step is easy to avoid. (if you have an international health record for example) or failing that, to negotiate (1$).
Next comes the visa stage itself. If you already have your e-visa in your pocket, you may be asked for 2 more$ just to stamp (the ink is expensive…) but it should make the transition much easier without too much “damage”. On the other hand, if you do the visa on arrival, things get worse.
Cambodians take their cinema very seriously and are directly aggressive.
If you ever arrive via the bus I mentioned just before and refuse the driver's "offer", it will be you who will have to face the customs officers with the pressure of the driver who will not fail to tell you that he will leave without you if it takes too long... Hence the option of coming to the border yourself, taking your time and then taking a leisurely bus after the border to reach your destination.
You must fill out the form and provide an identity photo and then provide the 30$, which as mentioned above, often turns into 35$ direct. If you don't want to take part in this organised racket, the customs officers won't give you any gifts, they'll yell at you, threaten you with not being allowed to enter and will even tear up your form, good atmosphere...
Why make it complicated when you can make it simple?
Some might be tempted to ask this question and give up by taking the all-inclusive option of 40$ with the bus. Certainly. Obviously it can be unnerving to be barked at by a sworn government officer… But it's still bullying and overall they're not patient, so if you stay polite and patient, it usually ends up passing.
In the end, it's up to you to decide whether, beyond the savings it can make, you want to participate in this lucrative business or not.
