We highly recommend taking an excursion to at Koh Tao Island when visiting Koh Samui!

Koh Samui is one of Thailand’s most famous islands, known for its luxurious resorts, laid-back atmosphere, and picturesque beaches. It’s part of the Gulf of Thailand, which typically experiences calm waters and favorable weather, especially between March and September. Here are some highlights: 

1. Chaweng Beach: Chaweng Beach is the heartbeat of Koh Samui’s tourism scene, offering a lively mix of beachfront bars, restaurants, and nightlife. If you’re looking for a balance of relaxation and entertainment, this is your spot. 

2. Luxury resorts and spas: Koh Samui is renowned for its luxurious accommodations. From private pool villas to wellness retreats, the island offers truly world-class spa experiences. 

3. Cultural attractions: Spots like the Big Buddha Temple (Wat Phra Yai) and the Secret Buddha Garden provide a glimpse into Thai culture and offer stunning views of the island. 

4. Island hopping: Koh Samui serves as a gateway to other stunning islands in the Gulf of Thailand, such as Koh Phangan, famous for its Full Moon Party, and Koh Tao, a diver’s paradise. 

Who should visit Koh Samui? 

Koh Samui is perfect for travelers who prioritize relaxation, luxury, and a slightly more exclusive vibe. It’s also a great choice if you prefer calmer seas, as the Gulf of Thailand is generally less affected by monsoons than the Andaman Sea. 

The Andaman Sea: Phuket and Krabi 

The Andaman Sea is home to some of Thailand’s most iconic beach destinations, including Phuket and Krabi. Known for dramatic limestone cliffs, turquoise waters, and world-class diving, this region offers an array of experiences. The best time to visit is between November and April, as the monsoon season can bring heavy rains during other months.
