The word “belbek” has many meanings–“strong back”, “big coming”, and others.
There is no single interpretation, but it’s clear that the valley bears the name of the river. From among all the versions, I best like the “dagger.”
The valley is a river bed with many tributaries which are like sword blades. It’s a long valley hidden in low “mountains”. The tourist spots I mentioned above can be found in its various parts.
But we visited friends and hiked that part of the valley where there are almost no tourists.
