When you go for water rafting, you are constantly putting on a life jacket and also are accompanied by a teacher. But the river current can flip you off the boat. Thus, while rafting you're always at the threat of drowning or injuring yourself in the water. Caving or cave expedition is among one of the most exhilarating experience tasks. Activity depends on the cave and how visitors negotiate presses, pitches, waters and rocks. Though caving has actually become much safer with safety devices but still tourists as well as adventurers are at danger of falling rocks, flooding, falling, hypothermia and also exhaustion.
