When crossing the border from Bangkok to Siem Reap, make sure to have the following documents ready:

Valid Passport: Ensure your passport has at least six months of validity remaining from the date of entry into Cambodia.

Cambodian Visa: Depending on your nationality, you may need to obtain a visa in advance or can obtain it on arrival at the border. 

Good news is, you can also easily apply for an eVisa online to visit Cambodia. It’s important to note that this type of visa is specifically for tourists, allowing a maximum stay of 30 days in the country. 

However, keep in mind that there are eight nationalities that are exempted from visa requirements. Citizens of Brunei, Indonesia, Laos, Malaysia, Philippines, Singapore, Thailand, and Vietnam can enjoy visa-free access to Cambodia. 

Departure Card: Fill out the departure card provided by Thai immigration when leaving Bangkok. Keep it safe as you’ll need it to exit Thailand.

Arrival Card: Upon entering Cambodia, you’ll need to fill out an arrival card. It’s usually provided at the border, but it’s a good idea to have a pen handy to fill it out quickly.

Supporting Documents: Carry any supporting documents required for your specific visa category, such as invitation letters, hotel bookings, or proof of funds.

Transportation Tickets: Keep your bus, train, or flight tickets easily accessible as you may be asked to show them at immigration checkpoints.

Once you’ve departed Bangkok and arrived at Aranyaprathet, the border town, it’s time to tackle the second step of your tour. This step involves crossing the border from Thailand to Cambodia at Aranyaprathet-Poipet. 

Here, you’ll pass through the immigration checkpoints of both countries, with Thai immigration on one side and Cambodian immigration on the other. 

Be prepared to present your travel documents, complete necessary forms, and follow the instructions of the immigration officers. 

Once you’ve successfully cleared immigration, you’ll be officially entering Cambodia and can continue your adventure towards Siem Reap.

Pro tip: No need to bother with changing your money into Cambodian riel, it’s just a scam! Stick with US dollars, they’re widely accepted everywhere in Cambodia (though some places might take Thai Baht—but at a poor rate). 

You don’t have to pay any border crossing fees either. Plus, don’t fall for anyone offering help to get a visa or cross the border, they’re probably up to no good. Only get your visa at the official Thai visa office, unless your bus company offers a special “VIP” visa processing.

Shuttle bus: Convenient shuttle bus services are available from the border to Siem Reap. These buses typically cater to tourists and offer a comfortable and hassle-free ride to your destination.

Taxi or private car service: If you prefer a more personalised and direct transportation experience, hiring a private car or taxi service is a great option. 

This allows for flexibility in terms of departure time and provides a comfortable and convenient journey to Siem Reap.

Shared van or minibus: Another popular choice is to join a shared van or minibus. These vehicles often depart from the border and gather passengers heading to Siem Reap. 

It’s a cost-effective option that offers a shared travel experience with fellow travellers.

Tuk-tuk: For a unique and authentic Cambodian transportation experience, you can opt for a tuk-tuk. These three-wheeled vehicles are a common mode of transport in Cambodia and provide an open-air ride to Siem Reap.

As you near Siem Reap, be cautious of drivers who conveniently forget your accommodation or insist that taxis are prohibited. 

Beware of tuk-tuks appearing out of nowhere, offering “free” rides, as they often seek commissions from guesthouses or tours. 

To avoid falling victim to this scam, it’s crucial to stay vigilant and be prepared. When dealing with the driver, firmly insist that you will not be paying any additional money or booking any tours through them. 

If you prefer to keep the peace and avoid unnecessary conflicts, you may consider tipping the driver a few dollars. However, remember that you are not obligated to do so.
