Famous for its world class palm fringed beaches, Koh Samui, also known as Ko Samui or Samui, is the second largest island in Thailand after Phuket. Located in the Gulf of Thailand off the mainland’s east coast, the island is only 45 minutes from Bangkok by and a few hours from other major air hubs in Asia such as Singapore and Hong Kong. Koh Samui has a total area of 229 square kilometres and is 25 kilometres across at its widest point. You can comfortably drive around the island in under 2 hours via the 60-kilometre ring road. As air links and infrastructure improved, the island developed from a backpacker’s haven into an internationally renowned resort destination and now attracts as many as a few million visitors per year. With high quality infrastructure and amenities, it now offers a broad spectrum of hotels including many high-end branded resorts, an excellent choice of restaurants, private hospitals, international schools and shopping facilities.
In terms of property types, residential real estate investment in Samui is primarily cantered around pool villas, attracting investors looking to enjoy the tropical island lifestyle with expansive outdoor living spaces. While the supply of condominiums on the island remains limited due to zoning regulations, Samui saw the release of its first upscale multi-use freehold beach resort condo project, Anava Samui, in mid-2024. However, there are still far fewer freehold condominiums on Samui compared to Phuket, contributing to the focus on villa investments. Property prices have risen alongside gentrification, with average villa prices, excluding the super-luxury segment, now similar to those in Phuket, and top-end properties listed for $8M USD or more.
in 2012 the island was granted municipal status and thus is now locally self-governing, Koh Samui has managed to preserve a lot of its island charm and island-feel with relatively little high-rise development.

Best Locations in Koh Samui to Buy Property
When looking at the best locations in Koh Samui to buy a property, the answer of course largely depends on the buyer’s individual preferences and reasons for purchase. How close they want to be to the main tourist hubs, restaurants, bars and nightlife, amenities such as the airport, the international hospitals etc, the importance of rental returns, closeness to a good year-round swimming beach, or preference for a more tranquil setting in a less developed part of the island are all factors to be assessed.
The main tourist hub of Koh Samui is Chaweng Beach in the north-east region with its long stretch of soft powder-white sand, numerous resorts, bars, restaurants and shopping facilities. Commercial property development, the most important amenities on the island, such as the airport, hospitals, shopping malls etc., and also residential real estate has naturally developed in and around the area of Chaweng. Hence, in terms of overall market demand for property, the most popular Northeast, in close proximity to Chaweng, is where a majority of property development has occurred and where most people, but not all, seek to buy property.
There is virtually no residential property for sale on or next to Chaweng Beach itself as all this real estate was long ago developed for hotels and resorts. Hence, the most sought-after areas are other locations in north-east region driven by factors such as quality of beachfront, quality of sea view, proximity to amenities, restaurants and bars. Within the Northeast, the areas most in demand for residential property are Choeng Mon and Plai Laem, Bo Phut and Chaweng Noi. All four areas have great beaches, Choeng Mon Beach arguably the best beach on the island, and offer stunning ocean and island vistas from their hillsides. Plai Laem also includes highly-desirable Tong Sai Bay, Tongson Bay around the north-east peninsula with a number of high-end resorts. Bo Phut includes Fisherman’s Village, which has a good range of high quality restaurants, chic bars and an a tasteful open-air shopping centre. Chaweng Noi, just south of Chaweng, offers magnificent ocean views of Chaweng Bay and a lot of high-end villa development is found on the hillside.
After Chaweng, the second most popular tourist town is Lamai on the south-east coast. As with Chaweng, the area of Lamai Beach itself has all been developed by hotels. However, A lot of residential property development can be found on the surrounding hillsides and nearby beaches such as Hua Thanon and Laem Set.
Other main areas worth noting for residential property include the north coast, partly due to the quality beach of Maenam, stretching to the north-west coast at Ban Tai/Bang Por – these have more peaceful beaches than Maenam but still great sand. For exclusive high-end beachfront villas, the west coast at Lipa Noi is popular due to the good quality of the beach and the sunsets. For expats and fulltime living, Ban Rak in the north-east is popular plus less developed areas in the south such as Taling Ngam and Laem Sor.
Getting Around
In recent years, the infrastructure of the island has improved dramatically. This has included the upgrading and widening of the ring and main roads around the island. Options for getting around include:
Songthaews – The cheapest form of transportation around Koh Samui, other on what walking or bicycles, Songthaews are converted pickups with two benches in the back and a covered roof for shade. Usually, there are tarpaulin sides that can be lowered in the case of rain. You need to negotiate the fare before taking your ride and you press a buzzer when you want to get off. You can use Songthaews to travel the major routes on the island.
Taxis
Usually yellow and red in colour, there is a good supply of taxis for use in Koh Samui though the prices are higher than elsewhere in Thailand. They very rarely use a meter and you should negotiate your fare beforehand.
Motorbike taxis
If you want to get around the island quickly and experience a thrill zipping in and out of the traffic, motorbike taxis are an option. Helmets must be worn of course, and these are not for the faint hearted.
Car Rental
There is a good supply of cars and four-wheel drive vehicles for rent on Koh Samui with a number of the major rental companies, such as hurts, having offices on the island. You will need to have an international driving licence and always be sure you’re properly insured as traffic accidents are very common.
Motorbike/Moped Rental
These are very popular form of transport, particularly for younger tourists and travellers. Mopeds can be rented from 150 baht per day. The law requires you to wear a helmet and if you don’t you will be fined. Though a very appealing form of transport due to price and flexibility, please be aware that the rates of death from motorbike accidents in Thailand are extremely high and this is especially so in Koh Samui with its mountainous terrain.
Environment and Infrastructure
A major project to improve the island’s ring road started in 2017. This has widened and reinforced the main ring road all the way around Koh Samui and reduced flooding from Improved drainage systems. The roads were upgraded with new stell-reinforced concrete plus asphalt blacktop, new sidewalks, additional streetlights, and run-off water collection. Also, to cope with the increased tourism, hotels, resorts and villas are required to have their own septic tank systems reducing the need for widespread wastewater treatment. Following these improvements, the infrastructure on Koh Samui is now generally better than that of the neighbouring islands of Koh Tao and Koh Phangan.
Property Market
A very significant proportion of Thailand’s GDP is accounted for by tourism (12% pre-pandemic) which is also a key driver of the country’s real estate market. On the back of the reopening of Chinese borders in March this year, tourist numbers have continued to rise dramatically from 11.5M in 2022, and projections for 2023 indicate visitors will reach 30 million (source BANGKOK, Feb 7 (Reuters), approximately 75% of pre-pandemic numbers.
