Dolphins and Benagil Caves Catamaran Tour from Lagos
Wild dolphins in the open ocean and iconic sea caves in a single unforgettable voyage
The Dolphins and Benagil Caves catamaran tour brings together two of the Algarve's most celebrated natural spectacles, guiding guests across open waters where spotted dolphins roam freely and past the dramatic rock formations that define this stretch of the Portuguese coast.
Aboard the spacious catamaran SeaMystic II, an experienced crew and an onboard marine biologist lead the experience from Lagos Marina. The marine biologist shares detailed insights into dolphin behaviour, diet, and social habits as the animals are observed in their natural environment.
The route passes through the most iconic cave systems of the Algarve, including the celebrated Benagil Cave and the formations near Ponta da Piedade. When sea and weather conditions allow, a stop for swimming adds an extra dimension to the journey.

This tour departs from Lagos Marina on the southwestern Algarve coast of Portugal, a region internationally recognised for its dramatic limestone sea caves, golden cliff formations, and rich marine biodiversity. The Algarve coastline — particularly the stretch between Lagos and Lagoa — contains some of Europe's most visited natural landmarks, including the Benagil Cave, which sits within the Algarve Marine Protected Area. The open Atlantic waters off the Algarve are a year-round habitat for several cetacean species, most notably the Common Dolphin (Delphinus delphis) and the Bottlenose Dolphin (Tursiops truncatus). Lagos itself is one of the main maritime tourism hubs in southern Portugal, with direct access to Ponta da Piedade and the wider Costa Vicentina. Travellers arriving by air typically use Faro Airport, located approximately 80 kilometres to the east of Lagos along the EN125 highway.
