Secallins

Yes — the rocky formations break the surface, creating natural snorkeling terrain at 3-5m depth. The Posidonia meadows are visible from the surface with a mask. Several centres include Secallins in snorkeling excursions.

Long-snouted seahorses (Hippocampus guttulatus) have been photographed here, associated with the Posidonia seagrass. They are extremely well camouflaged among the fronds — ask your guide for current sighting locations rather than searching alone.

One of the best options in the Sant Feliu area. Shallow (3-20m), negligible current, calm conditions, and an engaging underwater landscape with enough variety to hold attention without difficulty. Centres use the area for training dives.

Macro is the priority — a 60mm or 100mm lens captures seahorses, nudibranchs, and crustaceans hiding in the Posidonia fronds. Wide-angle works for the surface-breaking rock formations, but the site's real photographic value is in the small life among the seagrass.

Posidonia oceanica is an endemic Mediterranean seagrass, legally protected under EU regulation. Dense, healthy beds indicate good coastal water quality. The meadows at Secallins function as nursery habitat for juvenile fish and shelter species — including seahorses — that open rock does not support.
