We have a sighting guarantee, meaning we guarantee to sight at least one whale or dolphin species listed for the Azores, in Whale & Dolphin Watching activity. However, we cannot predict if it will be only whales, dolphins or both on a single tour since we work with wild animals, and their behaviour is unpredictable. If whales or dolphins species are not sighted during the tour, customer will have the possibility of another free tour, or in case of unavailability due to weather conditions, full refund.
