The Queen Sirikit Botanic Garden conducts research to conserve Thailand’s extensive natural plant resources. This place good attraction for Familay travelers. Visitors can walk through an indoor southern Thai forest, see the country’s largest public display of orchids (more than 400 species), and stroll footpaths past azaleas, rhododendrons, and many other flowering plants. The Basics Thailand’s first botanical garden comprises some 560 acres (227 hectares) of greenhouses, gardens, and plantations, all crisscrossed by nature trails. The greenhouses are particularly impressive, with collections of orchids, water lilies, carnivorous plants, and bromeliads. Since the gardens are so spread out, many visitors opt for a guided tour with transportation from one site to the next. If you’re pressed for time, it’s also possible to combine a visit to the gardens with a stop at a Hmong hill-tribe village (to learn about their sustainable agricultural projects) in as little as half a day.
