The trip Polignano is actually famous for
Polignano a Mare is a town built on a cliff with the sea working underneath it, and the only way to understand that is from the water. The standard circuit runs about 1.5 hours along a couple of kilometres of limestone, passing Grotta Palazzese under the restaurant everyone has seen photographs of, plus Grotta Ardito, Grotta delle Rondinelle and Grotta degli Innamorati. From below, the town stops being a viewpoint and becomes a wall with holes in it.
The boats are small local businesses rather than a fleet: one holds a licensed tour-operator registration with insolvency-fund cover and works 7-metre open boats, another family firm has run the same caves since 1993. That continuity is worth something when the weather is marginal and someone has to make a judgement call.
Where you board, and why it matters
Cave-tour boats leave from San Vito, the harbour hamlet roughly 2 km north of the centre; the bigger charters use Cala Ponte Marina, and Lama Monachile — the beach in the ravine that sells the town — has no boarding point at all. People book a boat, walk down into the ravine with their bags, and discover this at the wrong moment. We send the boarding point, in writing, with the confirmation.
Boat size decides the trip
This is the one decision that changes everything. The open boats that can actually enter the caves take up to 10 people, on hulls of about 7 metres. Anything larger works the coastline from outside — still beautiful, still worth doing, but not the same experience, and frequently sold with the same photographs. When we send options, each one says plainly whether it enters the caves or views them.
What it costs
Shared cave tours run roughly 25 to 35 EUR per person. Taking the boat privately is around 250 to 300 EUR for the 1.5-hour circuit, with a sunset run near 250 EUR and longer blocks listed at about 500 EUR for 3 hours and 1,000 EUR for 6. For a family of four or a group of six, private stops being a luxury and starts being arithmetic — and it buys you the departure time, which on this coast is the thing worth buying.
Sea, season and the day the water closes
The boats work March to October, wider than the general May-to-October visitor season. What decides your morning is wind, not temperature: northerlies raise chop along this stretch of the eastern coast and same-day go or no-go calls are normal. Mornings are usually calmest, with the thermal breeze building through the afternoon — book early in the day and early in your stay. One more local quirk: a cliff-diving event closes the water at Polignano to regular tours for its day each year, on a date that moves, so it is worth checking before you fix anything.
Who runs it, and what we do
The boats are Italian maritime businesses working under the pleasure-craft code; a skippered charter requires a skipper holding the patente nautica on a boat registered for charter use. We do not own boats or drive them. We take your dates and party to boats that are genuinely free, confirm the details directly, and stay reachable. Life jackets are carried to the boats’ safety rules and cave tours broadly welcome children, though minimum ages are set per boat rather than region-wide — worth checking with small children, since the small boats are open and lively.
Free cancellation up to 24 hours before departure is the norm here, and bad weather normally means a reschedule or a full refund on the individual boat’s terms, which we get in writing first.
