Al-Tannour forms part of the Damour River, which flows through Rechmaya. It is a waterfall that attracts hiking enthusiasts, as it creates a natural terrace near a large flat natural rock known as “Al-Blatta,” surrounded by trees with dense shade.
Rechmaya is also rich in natural springs, the most important of which are: Ain Seer, Al-Jawaz, Al-Ghazlaniyya, Taltiti, Mar Taqla, Ain al-Barrak, and Bir al-Mansoura.
The valley also contains numerous natural caves and grottoes.
