4 Best Sights in The Gulf Coast Beaches, Thailand

Chanthaburi's French influence is evident in its dual-spired Catholic cathedral, across the river from the center of town. Christian Vietnamese who migrated to the area erected the first church on this site in 1711, and the cathedral has been rebuilt four times since. The present Gothic-inspired structure was completed in the early 1900s, when the city was under French control. The best time to visit is during the morning market, when local foods, fruits, and desserts are sold on the grounds.

Chanthaburi's gem mines are mostly closed, but the Gem Market, which still operates in the center of town, attracts traders. You can often see them sorting through rubies and sapphires and making deals worth hundreds of thousands of baht. The market, an assortment of tables and stalls, takes place on Friday and Saturday along Sichan Road and various alleys off and near it.

The city's namesake beach fronts slightly murky waters, but its sand is golden and fine, and safe swimming areas have been added in recent years. You can rent shaded deck chairs by the hour, and food vendors and trinket merchants wander up and down the beach. The bay is usually crowded with small boats, Jet Skis, and other diversions. Parallel to the shore, Pattaya Beach Road has a landscaped walkway that separates the beach from the restaurants, shopping malls, and resorts on the opposite side. Amenities: food and drink. Best for: walking.

Off the northeastern tip of Koh Samui is Koh Fan (not to be confused with Koh Fan Noi), a little island with a huge Buddha. Indeed, the statue is better known as the "big Buddha." The island is best visited at sunset, when the light off the water shows it at its best.
