The Piscinas Naturais do Porto Moniz are seawater pools in black volcanic rock on the north-west coast of Madeira. According to National Geographic, lava ran down a valley and out to sea here within the last million years and hardened into the rock that forms the pool walls; the ocean flows over it and refills them. This file covers the managed complex with a sun deck and changing rooms, which DNoticias reported flying the Blue Flag for the 31st year in a row in June 2026. The free Aquário/Cachalote pools by the Madeira Aquarium are a separate bathing area in the same town. Source Source Source Checked
DNoticias reported on 8 June 2026 that the Piscinas Naturais do Porto Moniz raised the Blue Flag for the 31st consecutive year at a ceremony held that week. The newest dated photograph is Dietmar Rabich’s of 17 November 2025, taken days after storm Claudia (11–13 November 2025, per the photo’s Commons description). No report of closure or damage to this complex was found for 2025–2026; a December 2025 damage report concerns the Seixal pools, a different site in the same municipality. Source Source Reported

💡 5 things to know
- Walls made by lavaNational Geographic says that in Madeira’s most recent volcanic phase, in the last million years, lava flowed down an existing valley and out to sea where Porto Moniz is today, hardening into the rock that forms the pool walls. Madeira’s tourism office likewise describes the pools as formed by cooling lava. Source Source Checked
- Always fresh seawaterMadeira’s tourism office says the natural shape of the pools lets the sea in constantly, so the water is always being renewed. National Geographic adds that the incoming water sometimes carries fish and shrimp. Source Source Checked
- Two sets of poolsPorto Moniz has two bathing areas in lava rock: this managed complex with a sun deck, changing rooms and bar, and the free-access Piscinas Naturais do Aquário/Cachalote at the entrance to the town, which Visit Madeira says have no support or sanitary facilities beyond an outdoor shower, though they are lifeguarded in the bathing season. The town’s mayor named them separately in June 2026. Source Source Source Checked
- A long bathing seasonIn 2023 the official season here ran from 1 May to 15 October, 167 days. The town council claimed it was the longest in the region; a DNoticias fact check rated that false, because three Porto Santo beaches ran to 30 October. Source Checked
- 31 Blue FlagsIn June 2026 the pools raised the Blue Flag for the 31st consecutive year; DNoticias says the award recognises water quality, safety, environmental management and services. Source Source Checked
