Thailand’s largest island is an international magnet for beach lovers and serious divers, who enthusiastically submerge themselves in the Andaman Sea. Blue lagoons and salmon sunsets make for a dream-like atmosphere, and indeed, a vacation here can feel a bit surreal. Watersports are the most popular activities, though once you’ve had enough sun there’s still plenty to explore at the island’s aquariums, gardens, and Buddhist temples.

At nearly three miles long, Karon’s beach stretches on and on and on… so this might be the perfect spot for travelers who want as much space as possible around their beach blankets. TripAdvisor travelers say the diving is fabulous. And bring the kids-- Karon is known as a family-friendly town.
