The total protected area is around 1 367 decares. There are also a fishing zone for Balkan trout around 3 km long.

The waterfall is extremely beautiful and it is worth to walk away to get there (around 30 min). The total length of the main eco-road "Struilitsa-Kaleto-Laka" is about 4 km. For untrained tourists (about 2-3 hours in both directions). The eco track leads to “Lakata”, where exist a medieval settlement.
Today the area is a vast meadow surrounded by beautiful peaks. At 800 meters from the meadow, up and down the slope of the mountain, you can see the ruins of the famous Rhodope fortress “Kavursko Kale” (or just Kaleto). They survived in the period of VI-XIII century; and was captured by the Turks after a long siege.
