We did not purchase insurance through Sixt, but rather through our credit card company. The gas tank came about 7/8 full; this was noted on our walk through prior to driving the car off of the airport lot. No worries there; gas stations are plentiful all around the airport.

Driving was very easy. Just yield to the motorbikes as they are everywhere. Drove around the entire island on the first day. Took approximately 2 hours making stops along the way. If you have a smaller economy car you may have some issues with ground clearance on some of the back roads up in the hills of the interior hills( dont trust your GPS maps to make that distinction for you) otherwise it was very easy to get around on your own on the island!
KAYAK’s top tips for renting a car in Ko Samui
To call Koh Samui a tropical paradise is no exaggeration. The largest island in Thailand’s Chumphon Archipelago, Koh Samui has kilometres of sparkling coastline, waterfalls, temples and rainforests to explore. From Laem Yai Beach in the north to the tiny beaches of the Samui South Coast, you’ll find one of the most well-developed road systems in the region. This makes car hire in Koh Samui a great way to explore the island on your own schedule.
Samui International Airport (USM) has both a domestic and an international terminal. Both lead to a main arrivals hall, where you will find car hire kiosks for companies like Avis, Sixt, Budget, Thrifty and more. Picking up your Koh Samui car hire at the airport is a convenient option, as this is precisely where you’ll need to go when you leave the island. However, it’s a good idea to book online ahead of time to ensure you're able to get the vehicle specifications you want.
You’ll need to have an International Driver’s Licence to be eligible for car hire in Koh Samui. While the road quality is quite good compared to other islands in the region, you should still be prepared to find some potholes and difficult sections of road. For this reason, it’s a good idea to have insurance for your Koh Samui car hire.
There can be a wide variety of hazards on the road in Koh Samui, from stray dogs to massive tropical storms. Even after a storm has passed, there will often be a lot of sand, water and debris on the roads, making safe driving more difficult. You won’t find much by way of street lights, so it’s important to take extra care when driving at night. If you think a person or animal might be about to step out in your path, slow down and don’t be shy about giving a short, friendly beep of the horn.
It is advisable to familiarise yourself with the major road connections, for an easier experience when driving a hire car in Koh Samui. For example, Ring Road is the main road that circles around the island. It is a quick way to get to the beaches, restaurants and other destinations around the island. Chaweng Beach Road is another main road that runs through the heart of Chaweng Beach, one of the most popular tourist destinations on Koh Samui. It is home to many shops, restaurants and hotels. Lamai Beach Road is the main road that runs through the heart of Lamai Beach, another popular tourist destination on Koh Samui.

FAQs about renting a car in Ko Samui
What type of car is recommended for driving in Ko Samui?
If you plan on sticking to the coastal roads around popular resorts like The Passage Samui Villas & Resort or Anantara Bophut Koh Samui Resort, then a compact car may be all you need. However, if you’d like to venture inland to explore Namtok Tar Nim & Magic Garden, Wat Khunaram temple or waterfalls like Tartan Waterfall or Mountain Waterfall, then a 4X4 may be a better option. This will make the steep inland roads a lot easier. If you’ll be exploring the coast more extensively, a 4X4 will also help with sandy tracks and difficult sections of road.
What’s the speed limit in Ko Samui?
In the built-up areas of Koh Samui, you may find speed limits of 40 km/h, 45 km/h or 60 km/h. You’ll probably also notice that many of the locals don’t stick to these limits. However, when you’re getting car hire in Koh Samui, it’s essential to follow all posted speed limits. Once you’re on major roads like Route 4169 or Route 4170, the speed limit can get up to 90 km/h or more. However, the condition of these roads and traffic density varies greatly, so it’s important to keep an eye out for signs and drive to the conditions.

This was a super easy rental car experience. From booking, to payment, to picking up the car, to dropping it off -- everything was smooth and efficient. Communications with the Sixt representatives at Koh Samui airport was very helpful. The car was clean and came without issue. I would definitely rent with Sixt again!
They confirmed a different vehicle to what I required I call to discuss this and there was no answer. I went to the office and there was no empathy at all for my situation and we cancelled the order online.
