One of the most recognisable sea caves on the Ionian side of Santa Maria di Leuca, with three large openings converging into a single cavern.
The old page placed it in Felloniche–Patù. Official sources instead include it among the caves of Santa Maria di Leuca, in Castrignano del Capo. Felloniche remains only in the historic filename for migration.
The municipality describes three openings that merge into a single cavern.
This gives the cave its name.
It belongs to the western cave system encountered from Punta Ristola towards Felloniche.
Editorial parent: Santa Maria di Leuca.
OpenStreetMap places the entrance at 39.79610, 18.33750 in Castrignano del Capo.
Torre Marchiello is about 270 m west.
Municipal information presents this cave stretch as reached by sea.
Use an operator familiar with the caves and conditions.
Visible openings do not mean every boat can always enter.
Sea, swell, vessel size, current rules and skipper judgement.
The multiple openings allow light from different directions, making the chamber highly scenic.
Appearance changes with sun and boat position.
Tre Porte belongs to the wider prehistoric cave landscape of Leuca, close to Grotta del Bambino.
Do not treat inner passages as an unrestricted tourist route.
Any swim stop should be decided by the operator and daily conditions.
Do not swim there independently from shore or cliff-jump.
Viewing from the boat can suit families; boarding and accessibility depend on the vessel.
Ask about children, life jackets and reduced mobility.
Water, hat, sunscreen, light towel, waterproof case and a light wind layer.
No caving equipment is needed for a normal sightseeing tour.
