Thailand’s southern beaches attract travelers with their clean water and dramatic cliffs , but there’s more to explore in this Southeast Asian country. Lopburi for history buffsBypass the tour groups at the ancient city of Ayutthaya and head two hours north of the capital, Bangkok, for a peaceful walk through Thai history. Lopburi, one of Thailand's oldest cities, boasts Khmer-era temples and the uncrowded ruins of King Narai’s Palace, which was built in the 1600s. It’s also known for the monkeys that gather at Phra Prang Sam Yot temple in the center of town. Ban Krut for beach bumsIn Ban Krut, travelers will find one of the cleanest and quietest stretches of white sandy beach within driving distance of Bangkok. This sleepy seaside community, known mostly by locals, is a five-hour drive or six-hour train trip down the Gulf of Thailand. Don’t miss the magnificent Wat Tang Sai, a huge, fairy tale castle-like Buddhist temple. Cave for holiday hikersHiking trails, wetlands and forests make Khao Sam Roi Yot National Park a weekend adventure worthy of topping your Thailand to-do list. The park’s crown jewel is the extraordinary Phraya Nakhon Cave. Come early to catch the picturesque chamber flooded with morning sunshine that spotlights the royal pavilion that sits inside. River Kwai for nature loversMost visitors come for the beaches, but the rivers and parks in Thailand’s Kanchanaburi province have much to offer. Scenic trails and waterfalls abound in Sai Yok and Erawan national parks. Just two hours from Bangkok is the bridge made famous in the book Bridge over the River Kwai by French author, Pierre Boulle, and the 1957 Academy Award-winning 1957 film adaptation of the same name. Stay on the river at one of Kanchanaburi’s many floating hotels, where you can travel to your front door.
