Experience the Great Barrier Reef the way few people ever do. Located on the outer reef beyond Port Douglas, Undine Cay is a stunning tropical sand cay surrounded by pristine coral reefs, turquoise lagoons and some of the most spectacular marine life on the Great Barrier Reef. Unlike the larger islands and crowded reef pontoons, Undine Cay offers an exclusive castaway-style experience where your group can enjoy a true tropical paradise with very few other visitors around.
Your adventure begins aboard your private WindSwell vessel as we cruise across the sparkling waters of the Great Barrier Reef toward one of Far North Queensland’s most beautiful reef destinations. Led by our experienced local crew with more than 35 years of reef knowledge and your personal marine biologist onboard, you’ll discover hidden reef locations, incredible snorkelling sites and unforgettable wildlife encounters along the way. Upon arrival, you’ll step onto a breathtaking white sand cay surrounded by crystal-clear water and vibrant coral gardens. This ever-changing sand island feels like something straight from a postcard and offers the perfect setting for swimming, relaxing and exploring one of the world’s most iconic natural wonders.
One of the highlights of the day is our guided stand-up paddle boarding experience. Glide effortlessly across calm tropical waters while spotting turtles, stingrays and colourful reef fish beneath your board. The shallow lagoons surrounding the cay provide ideal conditions for beginners and experienced paddlers.
After your paddle boarding adventure, enjoy a fresh tropical fruit platter featuring local produce before preparing for an unforgettable snorkelling session. Beneath the surface you’ll swim amongst schools of tropical fish, vibrant coral formations, giant clams, sea turtles, rays and thousands of reef species that call the Great Barrier Reef home. The exceptional water clarity and healthy coral systems make Undine Cay one of the most rewarding snorkelling locations accessible from Port Douglas.
WindSwell specialises in private, personalised adventures. Your itinerary can be tailored to suit your group, whether you’re looking for a relaxing island escape or an action-packed day on the water. Looking for even more adventure? We will bring the gear for adrenaline-fuelled water sports where you can choose from wakeboarding, tubing or kitesurfing (experience necessary). E-foiling and scuba diving can be added to your adventure for an additional cost. For families, groups and anyone wanting to create magical memories, we also offer mermaid tail experiences onboard. Slip into a colourful mermaid tail and swim, snorkel or pose for photos around the stunning sand cay, a favourite addition for mermaids-at-heart.
