Built just to the east of the spectacular ruins of the capital of the Ayutthaya kingdom, a Siamese power destroyed by Burmese invasion in the 18th century, Ayutthaya is a modern Thai city studded with archeological wonders. Headless Buddhas and crumbling but still-beautiful reliquary towers and wats give evidence of the majesty of the civilization that was once centered here.

A visit to Pattaya is a wonderful way to explore the beaches along the Gulf of Thailand. Relaxed and family-friendly Jomtien Beach is a hot spot for watersports and seaside massages.

At night, tons of bars and strip clubs attract an adults-only crowd.

The wider province offers forests and caves to explore, and beautiful waterfalls.
