Grab a guide and spend a day whitewater rafting on the Tara River. When you enter a peaceful stretch, take the time to look up the soaring sides of Tara Canyon - the deepest in Europe - to a narrow strip of blue sky above. Amble by a solitary monastery or pause to rest on a sandy spit. Admire the tributary waterfalls and ancient Roman bridges along the way. You can travel like this for up to three days, camping at night on the banks of the Tara.
