Scuba diving at Arcanzil in Lisbon Coast

About This Site
Arcanzil is one of Sesimbra's most iconic reef dives, a rock pinnacle rising from around 15 m at the base of Cabo Espichel almost to the surface — its crown so shallow that the top rarely goes fully underwater, and in any sea it throws up spray and spouts against the cliffs at the foot of the cape. The signature of the site is its gorgonians: the dive usually works down to 18-22 m where dense fans blanket the deeper reef in a colourful carpet, backed by a classic reef profile of walls, a big canyon and cavern-like recesses hung with yellow sponges, anemones and nudibranchs. Sitting on the exposed south-western tip of the Setúbal Peninsula, it is a versatile, scenic dive that ranks among the region's most-listed sites when conditions allow.

Arcanzil sits at the south-western base of Cabo Espichel, the westernmost tip of the Setúbal Peninsula, projecting straight into the open Atlantic — so unlike the sheltered Arrábida reefs east of the cape, it takes the dominant W-NW Atlantic groundswell almost head-on. The whole southern-to-western arc, from SE round through S, SW and W to WNW, is fully open ocean and the exposed window; W-NW long-period swell wraps directly onto the pinnacle and the shallow crest breaks in any sea. The cape's cliffs and body shield only the landward N-NE-E sectors, with the western cliffs giving partial cover to the NW-NNW. The result is a genuinely swell-exposed site: calm and superb in a settled Atlantic, unworkable when any westerly swell or southerly wind is running.
