Riserva Naturale Cavagrande del Cassibile
About 35 km south-west of Siracusa, the Cavagrande del Cassibile nature reserve hides a dramatic limestone canyon carved by the Cassibile river, with a series of emerald-green natural pools connected by small waterfalls that look more like something from a Greek island than mainland Sicily. It is one of the most beautiful and least-known swimming spots in southern Italy.
The Canyon & the Pools
The main trail descends steeply from the car park at Avola Antica into the gorge — the walk down takes about 40 minutes and involves some scrambling over rocks. The effort is rewarded by a sequence of pools called the Laghetti di Avola, where the water is crystal-clear, cold even in August and ringed by white limestone walls up to 100 metres high.
The largest pool is deep enough to jump into from low ledges and popular with young Sicilians on summer weekends. Arrive on a weekday before 10:00 to have the pools largely to yourself — the canyon acoustics make the sound of the waterfall almost meditative.
Wildlife & Scenery
The reserve is home to peregrine falcons that nest in the canyon walls, golden eagles, and the rare Sicilian wall lizard. The vegetation shifts from Mediterranean scrub at the top to lush riparian forest — fig trees, oleander and wild mint — at the canyon floor.
The light inside the gorge is extraordinary in the early morning when shafts of sun reach the water and turn it turquoise. This is a legitimately photogenic natural location that rarely appears in mainstream travel coverage of Sicily.
Practical Essentials
Wear proper hiking shoes for the descent — sandals are dangerous on the loose scree sections. Bring more water than you think you need, a picnic and a towel. There are no facilities at the canyon floor.
The reserve is managed by the Corpo Forestale della Regione Siciliana. Access is free. The nearest town for supplies is Avola, a 10-minute drive, which also happens to be the home of the Nero d'Avola grape and has good bars for a post-swim granita.
