South of Otranto is the fabulous little bay of Porto Badisco. Not really discovered by tourists this beautiful bay is frequented mostly by locals. It’s a great spot for snorkelling too. There is a car park just off the coastal road and it’s a short walk down the cliff path to the bay itself. There’s a great bar / restaurant at the top of the bay access road perfect for lunch
You can drive down to the bay itself where there is another car park. On a Saturday in June there was plenty of parking but it will probably be very busy in July / August. There is also a restaurant by the bay. We’ve eaten there once but found it expensive and mediocre at best, the one at the top is definitely better.
