Spend a half-day from Peniche exploring Berlenga Grande by catamaran: short coastal hikes, a 17th-century fortress, and included snorkeling in a UNESCO Biosphere Reserve. Practical guidance on timing, footwear, and marine rules sets you up for a smooth trip.
More ways to explore the area's outdoor wonders
The catamaran slips out of Peniche at dawn and the Atlantic opens like a living map: wind-driven ripples push the hull toward a cluster of granite and limestone that rises from deep blue. On Berlenga Grande, gulls wheel and the fortress walls of Forte de São João Batista loom, weathered but proud, as currents dare you closer to kelp beds and hidden coves.
