Accessible only from the sea, visitors can explore the cave by boat, kayak, or stand-up paddleboard. The nearby Benagil Beach serves as the main launching point for tours, and guided excursions are available throughout the year. Swimming to the cave is possible but discouraged due to strong currents and heavy boat traffic.

The surrounding coastline is equally breathtaking, with limestone cliffs, hidden coves, and viewpoints offering panoramic ocean views. Early morning and late afternoon visits provide the best lighting for photography and a more peaceful experience.
