Four times a day, 13 billion cubic feet of water are forced in and out through a passage 150 metres wide and 31 metres deep. On our exciting journey through this wild landscape there is a good chance we will be able to observe sea eagles whilst also taking in the awesome scenery and observing parts of the Caledonian Fold Belt, a range of mountains dating back over 250 million years. While we sit safely and comfortably in sturdy rubber boats, operated by highly experienced and knowledgeable pilots, you can be sure to enjoy a day of rare adventure in harmony with nature, eagles and the deep blue sea.
