This kind of adventures, comparatively new in most parts of the world, are not so popular in Bulgaria. It is a great way to see wonderful Bulgarian territory from another point of view. Trekking in the canyons is on virgin territory, at least for tourists. Less than half a dozen canyons are known to "outsiders", and only the local people are at home in the wilderness of rocks, precipices, cliffs, waterfalls and hidden valleys of Bulgarian mountains.
