Trip Overview

  • Experience the riveting cosmic event of a rare total solar eclipse from the best possible vantage point, directly on the centerline, as the brilliance of the Coral Coast is plunged into darkness. 
  • Cruise for 10 nights down the coast of Western Australia, home to some of the darkest skies in the world, allowing for incredible stargazing of the Southern Skies from the ease and comfort of the ship’s top deck. 
  • Witness a variety of dazzling landscapes of Western Australia’s colorful Coral Coast, home to white sand beaches, oceans painted with azure blue hues, rugged red outback desert and the world’s longest fringing reef.
  • Snorkel pristine reefs and coral gardens including the World Heritage Sites of Ningaloo Reef and Shark Bay.
  • Encounter an abundance of wildlife - rare birds, land animals and marine life – including a chance to swim with mighty whale sharks and manta rays, two of the world’s largest harmless fish.
  • Engage with Indigenous Australians and learn about the world’s oldest living culture during visits to sacred Aboriginal sites.
