Why Koh Samui for a Anniversary Escape trip
For a celebration, Samui offers romance with a sense of occasion. Choose a grand suite or villa above the sea and arrange a private chef's dinner on your terrace, or book a beachfront table timed to sunset on the west coast. A private yacht to Ang Thong's limestone islands makes a fitting centerpiece, and a visit to Wat Phra Yai, the island's Big Buddha, adds a reflective moment.
Set in the Gulf of Thailand, Koh Samui is a hilly, coconut-palm island ringed by soft-sand beaches and quiet bays. Its luxury leans intimate and relaxed: hillside villas with sweeping sea views, beachfront resorts on gentle bays, and easy access to the protected islands of Ang Thong Marine National Park.
When to go: January to April is typically the sunniest, driest stretch, and the island often stays pleasant through the summer months when Thailand's west coast is rainy. The heaviest rain usually falls from October to December, during the Gulf's northeast monsoon.
