The Character of Koh Samui
One of the most striking features of Koh Samui is its mix of landscapes. The coastline is lined with sandy beaches, from the lively Chaweng Beach with its restaurants and nightlife, to quieter spots like Bophut and Lipa Noi where life moves more slowly. Inland, the scenery shifts to coconut groves, jungle-covered hills, and waterfalls that provide a refreshing break from the heat.
The island also has a welcoming spirit. Locals are friendly and often eager to share their traditions, whether through food, music, or festivals. Songkran, the Thai New Year water festival, is especially lively on the island, with celebrations filling the streets. This mix of natural beauty and cultural warmth is what makes Koh Samui such a memorable destination.

What to Do in Koh Samui
1. Relax on the Beaches
Koh Samui’s beaches are the main draw for many visitors. Chaweng Beach is the busiest, with long stretches of sand and plenty of cafés, bars, and shops nearby. Lamai Beach offers a slightly quieter setting but still with a good choice of restaurants. For those who prefer something more peaceful, Silver Beach and Maenam Beach provide a calm escape with fewer crowds.
2. Visit Temples and Landmarks
The Big Buddha Temple, or Wat Phra Yai, stands on a small rocky island connected by a causeway and is one of the most recognisable sights in Koh Samui. Another highlight is Wat Plai Laem, with its colourful statues and lake setting. Hin Ta and Hin Yai Rocks, shaped by nature in unusual forms, are also among the island’s curious landmarks. Each of these spots offers a glimpse into the island’s cultural side.
3. Explore Waterfalls and Nature
Inland, the island hides natural gems such as Na Muang Waterfalls, where visitors can swim in pools at the base of the cascades. Jungle treks and viewpoints like Lad Koh give panoramic views of the coastline. Exploring these areas shows another side of Koh Samui beyond the beaches, one filled with greenery and a sense of adventure.
