About this tour

Ria Formosa is home to one of the largest seahorse communities in the world.

On this tour you will have the opportunity to observe this fantastic species in its natural habitat. The two species that reside in the Ria Formosa are: the long-snouted seahorse (hippocampus guttulatus), and the short-snouted seahorse (hippocampus hippocampus). You will also have the opportunity to observe other species such as octopuses, cuttlefish and sea cucumbers. It is also possible to observe the traditional seafood catch.

The skipper, who will guide you throughout the tour, will provide all the necessary information, helping you throughout the seahorse identification activity. The activity takes place within the Ria Formosa lagoon system and the diving activity is carried out without an oxygen bottle, just diving goggles and a diving tube for breathing.

The depth of the water will be between 1.50m and 1.80m, therefore, experience in swimming is necessary. The tour will take place on a boat to the place where you can dive and watch the seahorses.

Due to the species being on the verge of extinction and having to be very protected, every care will be taken to not interfere with its natural habitat.

Snorkeling equipment, goggles and diving tube will be provided.
RECOMMENDATIONS :  Bring a towel and bathing suit.

Sea Horse spotting

Lovely snorkelling morning in the Ria Formosa to see the Sea Horses (which we did!) guided by Miguel who was very friendly and informative. Safe for younger children (ours was 6) assuming they can float about in a pool with a snorkel - water is calm, protected and only a couple of meters deep.
