Peniche is a working fishing port and surf hub on Portugal's west coast, and it is the jump-off point for the Berlengas Nature Reserve, a UNESCO Biosphere Reserve (2011) offshore. Divers come for granite walls, caves, and a dense cluster of wrecks, with temperate Atlantic life like octopus, conger eels, lobsters, and schooling fish. Snorkelers and freedivers get their best days in sheltered coves around Berlenga Grande when the sea is calm and visibility opens up.
Summer is the main season for reliable boat crossings, with water commonly 16°C to 20°C. Outside summer, swell and wind can cancel trips, so build a buffer day and keep a topside plan. On land, stack cliff viewpoints (Cabo Carvoeiro), surf sessions at Supertubos, and easy day trips to Obidos and Nazare.
