Just an hour from Lisbon, hidden in the lush folds of the Arrábida Natural Park, lies an ethereal coastal realm—a blend of jewel‑blue water, pine‑draped mountains, and graceful bottlenose dolphins dancing in the Sado estuary. It’s nature and magic, quietly coexisting.
This region, protected since 1975 and now under UNESCO Biosphere consideration, is a haven for wildlife and sustainable adventure-. Here, the easy beaches and scenic cliffs of Arrábida meet the dolphin‑rich waters off Setúbal and Tróia, making it Portugal’s most enchanting marine escape.
