Why Koh Samui for a Honeymoon trip
Samui's hillsides were made for honeymoons. Pool villas terraced above the bays look out over the Gulf, giving couples sunrise views and complete privacy. On the west coast, sunsets over the water set the stage for dinners on the sand. Spend a day sailing to Ang Thong Marine National Park for kayaking and hidden lagoons, and save evenings for in-villa barbecues or a stroll through Bophut's Fisherman's Village.
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.
