Ko Samui, Thailand's second largest island, is located in the Gulf of Thailand, off the east coast of the Kra Isthmus. It's known worldwide for its palm-fringed beaches, coconut groves, and dense, mountainous rainforest, plus luxury resorts and posh spas. The 12m-tall, golden Big Buddha statue at Wat Phra Yai temple is a major landmark, offering stunning sea views. The island's bustling nightlife, particularly in areas like Chaweng and Lamai Beach, invites visitors in with culturally-infused entertainment, while the Ang Thong National Marine Park, a protected archipelago of over 40 islets, offers exceptional snorkelling and diving opportunities. Ko Samui is an ideal destination for both adventure seekers and those looking for relaxation in a tropical paradise.
