Ayutthaya Siam's former capital is a day trip into Thailand's past. Dozens of tranquil temples and crumbling palaces are spread over a wide island on the Chao Phraya. The best way to visit is to book a trip on a riverboat from Bangkok. 50 miles north of Bangkok; www.tourismthailand.org
Kanchanaburi This docile river town is worth more than a day trip. While the bridge over the River Kwai is disappointing, the Death Railway is a thrilling ride amid stunning scenery. Afterwards, relax at one of the floating restaurants in town. 81 miles northwest of Bangkok; www.tourismthailand.org
Khao Yai Hiking unspoiled jungle mountains, animal spotting, rafting, and swimming in waterfalls make this Thailand's favorite national park. Luxurious resorts welcome discerning eco-tourists just outside the park. And do stop at a winery or two to discover the New Latitude Wines. 75 miles northeast of Bangkok; www.dnp.go.th
Koh Kred Get away from Bangkok's bustle at this serene island. Low-key attractions include browsing for pottery, walking among fruit orchards, circling the island on bicycle along elevated walkways, and sampling ethnic Mon cuisine. 10 miles north of Bangkok; www.bangkoksite.com/Nonthaburi/KohKret1.htm
Koh Samet The closest island paradise to Bangkok is a real treat. A couple hours southwest of Bangkok, invitingly clear water, super-clean beaches, and fantastic seafood restaurants beg Bangkokians and discriminating travelers. Smart, low-key boutique resorts mean less backpackers and more style. 124 miles southwest of Bangkok; www.kosamet.net
Muang Boran The world's biggest open-air museum packs all of Thailand into a sprawling park filled with replicas of the country's major cultural and natural sights. Rent a bicycle and visit anything you might miss on your trip. The Floating Village is particularly charming. 21 miles southeast of Bangkok; www.ancientcity.com
