Things to do in Koh Samui

Go to the Beach

Since Koh Samui is an island, you can’t book cheap airfares from Sydney to Koh Samui without spending some time at the beach. Koh Samui has so many incredible beaches to choose from. Chaweng Beach is located in the largest town of Koh Samui. It’s the busiest beach on the island and is lined with lots of restaurants and bars. Chaweng Beach is one of the top nightlife areas on the island. If you prefer quiet and relaxing beaches, there are plenty of them as well. Lamai Beach is located in a smaller town. It’s peaceful, but still within walking distance of many restaurants. Maenum Beach is one of the most affordable areas to stay on Koh Samui. The area isn’t as developed as some other towns around the island, giving it a very relaxing and natural feel. The beach is quiet, lined with palm trees, and within walking distance of a few cafes, restaurants, and hotels.

Visit the Temples

Thailand is a very spiritual country, and Koh Samui is no exception to that. All throughout the island, there are amazing temples for you to visit. Two of the most popular to visit are Wat Phra Yai and Wat Plai Laem. Wat Phra Yai is located right next to the ocean and has a golden Buddha statue. This statue is known as the Big Buddha of Koh Samui. Wat Plai Laem is a temple with statues honouring both Buddha and Guanyin—the goddess of mercy and compassion. Both of these temples were built in traditional styles and are beautiful to visit.

Na Muang Waterfall

This waterfall is located in the jungle and is actually made up of two separate falls. The first waterfall flows into a pool where you can swim. Hike about a half hour uphill, and you’ll find the second part of the waterfall. Visiting the waterfall is a great way to experience the jungle of Koh Samui and see that the inland part of the island can be just as amazing as its beaches!

Ang Thong Marine Park

Off the coast of Koh Samui, this marine park is made up of 42 small islands. The area is full of things to do and makes for a great day trip from Koh Samui. The Ang Thong Marine Park is particularly known for its great snorkelling and diving. It offers so many other things to do as well, including beaches, jungle, hiking trails, and plenty of water sports. Mae Koh is one of the islands within the marine park and has a hike with amazing views of a natural pool called the Emerald Lagoon.

Nathon Town

Located near the ferry port, this town is the capital of Koh Samui. Nathon Town is full of great restaurants and shopping. The main attraction in town is the row of old Chinese shophouses. You can buy a range of souvenirs, and the shophouses specialise in gold products.

Laem Sor Pagoda

Located in the very south of Koh Samui, this tiered pagoda is located right on the beach. The pagoda is golden and shines as the sun reflects off the ocean onto its tiles. The pagoda is a temple honouring Buddha, and at the bottom of it are two colourful statues of yaks who are there to guard it. The pagoda makes for some great photo opportunities, and the beaches around Laem Sor are some of the best in Koh Samui. This is the area to go for a quiet experience without too many tourists around.

Best time to visit Koh Samui

When should you book cheap flights from Sydney to Koh Samui?

Koh Samui has both a wet and dry season due to its tropical location. However, the wet season only lasts from October to December, and the rest of the year is hot and sunny.

During wet season, rain storms are common and ocean waves get stronger. Weather is unpredictable at this time of year, and bad storms can happen at any time. With all the rain, roads often become flooded during this season.

But if you book cheap airfares from Sydney to Koh Samui during any other month, you’ll experience almost perfect tropical weather. Temperatures are hot, and it’s almost always sunny. Since Koh Samui is in the tropics, tropical storms can happen any time of the year. But outside of rainy season, these storms don’t last long. If it starts to rain, pop into a cafe, and it will most likely be sunny again when you’re ready to leave.

For the smallest chance of rain, and the most sun, book return flights from Sydney to Koh Samui in February or March. Weather is the most perfect during these months.
