The Phataem National park covers 340 square kilometers of spectacular scenery close to Laos, divided by the Mekong river. Arriving at Pha Taem national park you will be greeted by Sao Chaling, a natural rock formation made of sea shell fossils, looking like a giant mushroom, which was actually created 130-180 mio. years ago, when the dinosaurs was still walking around. Also here you will get a stunning bird-eye view over the Mekong river and its surroundings. We continue by foot to witness the 300 prehistoric cave paintings done more than 3000 years ago, including fish traps, elephants, human hands and geometric designs.
