Dolphins & Benagil Caves from Portimão
A complete experience with a local guide and marine biologist
Departing from Portimão Marina, this experience takes you out into the open ocean to encounter dolphins in the wild and admire the impressive rock formations of the Algarve coast. The Dolphins & Benagil Caves – Catamaran tour combines two of the Algarve’s most remarkable highlights in one journey: dolphin watching in their natural habitat and a visit to the iconic Benagil Cave.
Out in the open ocean, you will have the opportunity to search for dolphins in their natural habitat, accompanied by a marine biologist who explains the most common species in the region, their behaviour and fascinating insights into marine life. Among the most frequently sighted species are the Common Dolphin (Delphinus delphis) and the Bottlenose Dolphin (Tursiops truncatus).
The route also includes a passage along golden cliffs and caves sculpted by time, culminating in a visit to the iconic Benagil Cave — one of the most impressive natural landmarks in the Algarve.
