A boat excursion into a deep-water canyon known for blue and sperm whale sightings, with departures timed for the calmer, clearer conditions of the early morning. Outside the November to April season, a Polhena Reef snorkelling trip substitutes and we tell every guest plainly at booking which version of the experience their travel dates will actually deliver. Sightings are never guaranteed on any single trip, but the proximity of this particular canyon to shore makes it one of the more reliable whale-watching bases anywhere in the world.
