Koh Samui Travel Guide: Koh Samui at Glance
Koh Samui, the second-largest island in Thailand (only smaller than Phuket), covers about 230 km² (56,800 acres). Famous for its long sandy beaches, picturesque coconut trees, and vibrant coral reefs, the island has seen a big economic change.
Once dependent on agriculture and fishing, Koh Samui changed dramatically in the 1980s with the opening of an airport, which led to mass tourism.
The island is perfect for water sports like diving, snorkeling, and kayaking, and it offers a wide range of accommodations, drawing over 1.2 million visitors each year. Beyond its beautiful beaches and clear waters, Koh Samui has a lot to offer.
From scenic waterfalls to a giant Buddha statue, lively night markets, and the stunning Ang Thong National Marine Park, there’s plenty to see and do in this unique destination.
Koh Samui Travel Guide: When Is the Best Time to Visit Koh Samui?
The best time to visit Koh Samui is during the dry season from December to February. You’ll get sunny weather, calm seas, and nice temperatures, perfect for the beach and outdoor fun.
Here’s a quick rundown:
- Dry Season (December to February): Best weather with sunny skies and low humidity. Great for beaches, diving, and snorkeling. Most crowded and pricier.
- Hot Season (March to August): Hot and humid. Still good to visit, especially in March and April. The Songkran Festival in April is a must-see.
- Rainy Season (September to November): Lots of rain and occasional storms. Fewer tourists and cheaper accommodations. You might still catch some sunny days.
For the best experience, go during the dry season.
Koh Samui Travel Guide: How to Get to Koh Samui?
Koh Samui has an international airport. The easiest way is a direct flight from Bangkok (1h 15min), Chiang Mai (1h 45min), Pattaya, Phuket, or Krabi.
Bangkok Airways operates most flights, with prices starting at 2200 baht from Bangkok and 3000 baht from Chiang Mai.
Alternatively, combine land and sea transport:
- Bus or train from Bangkok to Surat Thani, then ferry to Koh Samui. Total journey takes about 14.5 hours and costs 1000-1500 baht (30-45 USD), depending on transport choice and class.
- Train from Krung Thep Aphiwat Central Terminal (Bang Sue Grand Station) in Bangkok to Surat Thani (8-12h), bus to Don Sak pier, then ferry to Koh Samui (1.5h). Cheaper but longer than flying.
- Fly to Surat Thani from Don Muang Airport in Bangkok, then take a ferry to Koh Samui.
Prices may vary depending on season and availability. Always check current rates before traveling.

When deciding where to stay on Koh Samui, consider these popular areas:
- Chaweng Beach is the go-to spot for nightlife and entertainment, with vibrant bars, diverse restaurants, and a stunning beach. Accommodations range from luxury resorts (10,000+ baht/night) to budget guesthouses (500-1,500 baht/night).

What to Do on Koh Samui?
One of the best things to do on Koh Samui is to take a speedboat ride to Ang Thong National Marine Park, located about 30 km away.
This stunning group of 42 islands, covering 102 km² (about 25,200 acres), features breathtaking landscapes like limestone cliffs, hidden coves, white sandy beaches, and emerald lakes.
The park is teeming with wildlife, including otters, langurs, eagles, hornbills, turtles, and iguanas. The clear waters are perfect for snorkeling.
Don’t miss the viewpoint on Ko Wua Ta Lap Island. The short but steep hike up offers spectacular panoramic views.
While many visitors opt for day trips from Koh Samui or nearby Koh Pha Ngan, staying overnight on Ko Wua Ta Lap Island is also an option. There are six bungalows and a camping area available.
For the best experience, visit between March and April. Avoid November and December due to the monsoon season. Note that there’s a 300 baht entrance fee per person, usually not included in the tour price.
Hin Ta & Hin Yai Rocks (Grandma & Grandpa)
Another must-see on Koh Samui is the fascinating rock formations known as Hin Ta and Hin Yai, also called Grandfather and Grandmother Rocks.
Located on the southeast coast between Lamai and Hua Thanon, these rocks are tied to an interesting local legend.
According to the story, Grandpa Ta Kreng and Grandma Yai Riem set out to propose on behalf of their son but tragically disappeared at sea during a storm. They are said to have been transformed into rocks resembling genitalia, adding a unique touch of folklore to the site.
To get there, stroll down a narrow alley lined with local shops selling souvenirs, handicrafts, drinks, and traditional Thai sticky candies called kalamae.
When you reach Hin Ta and Hin Yai, you’ll be treated to stunning views of the bay—an ideal spot for memorable photos of your vacation.
Na Muang Waterfalls
No Koh Samui travel guide is complete without mentioning Na Muang Waterfalls. Set among lush tropical greenery, these stunning waterfalls offer great views and the chance to cool off in natural pools.
The first waterfall, Na Muang 1, is just a two-minute walk from the parking area and is very popular with tourists and locals alike. A short 30-minute hike will take you to the second waterfall, Na Muang 2, where you can enjoy breathtaking views and a peaceful setting.
The best part? Visiting Na Muang Waterfalls is free, making it an easy and enjoyable experience for everyone. For the best experience, try to visit early in the morning or late in the afternoon to avoid the crowds and fully enjoy this natural wonder on Koh Samui.
Sunday Night Market in Lamai
If you love street food and shopping, Lamai Night Market is a must-see, happening every Sunday.
Starting around 4:00 PM, you’ll find stalls lined up along Had Lamai Street, serving a wide range of classic Thai dishes like stir-fry and curry.
Make sure to try the freshly caught fish and seafood, and treat yourself to sweet roti (Thai pancakes) with banana, condensed milk, and chocolate.
The lively atmosphere is enhanced by live performances from local artists and musicians. Lamai Night Market promises a great mix of delicious food and fun shopping, making it a highlight of your visit to Koh Samui.
Big Buddha Temple
Another one of the best things to do on Koh Samui is to visit the stunning Big Buddha Temple, also called Wat Phra Yai. This popular spot is one of the island’s biggest attractions.
At the temple, you’ll see a huge golden Buddha statue standing over 12 meters (39 feet) tall on a high pedestal. It’s one of the largest Buddha statues in Thailand.
The temple grounds also have a smaller Buddha statue and a lively souvenir market. Nearby, you’ll find various restaurants, shops, and the beautiful Big Buddha Beach.
When you visit, be sure to dress modestly (covering your arms and legs) and take off your shoes before entering. The temple is free to visit, making it a great way to experience the cultural side of Koh Samui.
