Kanchanaburi is Thailand's third largest province, covering an area of 19,486 square kilometers. The provincial area is mountainous and borders Myanmar to the west. The province of Kanchanaburi consists of 13 districts or Amphoe of which Amphoe Muang, Amphoe Sai Yok, Amphoe Thong Pha Phum, Amphoe Sangkhlaburi, Amphoe Tha Muang, Amphoe Bo Phloi, and Amphoe Si Sawat are tourist destinations.
  
Kanchanaburi is the site of the world-famous Bridge Over The River Kwae, immortalized in books and movies, and is noted for rugged natural beauty where mountains and river valleys have inspired development of hydro-electric power and where labyrinthine reservoirs provide further scenic elements to the province's natural beauty. Beyond the compact provincial capital, some 130 kilometers, and a comfortable 2-hour drive from Bangkok, where the Kwae Yai and the Kwae Noi rivers unite to form the Mae Klong River, Kanchanaburi unfolds in progressively arresting scenic beauty in a landscape characterized by several waterfalls, caves once inhabited by Neolithic man, national parks and tranquil riverside and reservoir settings.
 
Opportunities abound for rustic living aboard rafts on dazzling rivers and reservoirs, and provide the focal point for memorable holidays for nature lovers who delight in natural surroundings and pleasures without sacrificing basic comforts.
