While the Benagil Cave is one of the most famous sea caves in the Algarve, this tour does not include landing inside.

During the visit, the guide points out various cave features and explains their geological and cultural significance. The short stop—around five minutes—is enough to capture photos and admire the famous rock formations without the need to disembark.

The highlight for many on this tour is dolphin sighting. The marine biologist onboard provides educational commentary about the six different dolphin species inhabiting Algarve waters. The team actively searches for dolphins, and reviews frequently mention large pods and frequent sightings.
Some trips report seeing over 100 dolphins, with multiple species observed. The biologist’s insights add an educational element, helping passengers understand dolphin behaviors and the importance of marine conservation.
