Tsakonian rocks feature the town of Leonidion. These red vertical cliffs rise up to 300 meters high above the town. The Tsakonian rocks in the position they are, and having a southern exposure, affect the climate of the valley of Leonidio. They protect the valley from the north side, while on the warm days they create favourable conditions for crops and the development of greenhouses. Their importance for biodiversity is also great. Within the walking distance to the town they host endemic species chasmophyte Centaurea leonidia. The Tsakonian Rocks also present habitat for birds such as the peregrine rocks (Falco peregrinus), the kestrel (Falco tinnunculus), the vrachotsopanakos (Sitta neumayer), the vrachochelidona (Ptyonoprogne rupestris) and others.
