Tinetto islet has a 300-meters-long circumference and has a height of 18 meters above sea level.

It’s only just a little larger than a rock but it’s very important because there are the rests of very ancient religious buildings on it, and also because it guests the typical “wall-lizard”, which lives exclusively in this place.

Tinetto islet is quite next to Tino Island.
The first hermits who lived there, could reach the next Tino Island by walking on the rocks surfacing on the water.
On the islet there are ruins of an ancient 6th century nunnery, with its tiny cells. There’s no vegetation, but rare herbs and lichens, all dried up by the     
sea. We can also admire valuable evidences of an ancient rural architecture: there is a 5th century “hermitage” and a little two-aisles church. Some recent historical reserches have proved it is the first ligurian church with this structure.
Tinetto was a medieval hermitage, then turned into a “castigo” by the lords of the place.
    
On the islet there’s a big cave, with a two-meters-high opening hole, on a depht of 19 meters. After a walk of about 30 meters, following the light ray glimmering from the top, people can go out through a chimney that opens on the surface in a split of the rock, just in the centre of the islet.
The exit route is quite different than the entering one, but it’s equally very practicable.
Plays of light and shadows created by the sun rays are particularly evocative.
All around the exit, a colony of Parazoanthus axinellae and some Petrosia ficiformis formations, offer the best habitat for specimens of Discodoris atromaculata and Flabellina affinis.
Into the sea around Tinetto, it’s very easy to meet congers, morays, craw-fishes and the Paramuricea Clavata already from a depht of 15 meters.
