See the spectacular natural wonders of Horizontal Falls and Montgomery Reef, Australia's largest inshore reef. Departing from Derby, one of our experienced pilots will guide you on a spectacular helicopter flight across the mudflats with their intriguing aerial patterns created by some of the world's largest tides, and over the rocky Kimbolton Ranges and spectacular Kimberley coastline. The best is yet to come as you fly over Collier Bay and the Kingfisher Islands to the incredible Montgomery Reef, which covers more than 300 square kilometres! On a low tide, the reef emerges from the water, creating rushing waterfalls and incredible patterns that only a few people get to see from the air. On your return flight, fly over the famous Horizontal Falls before landing on the houseboat to join your tour group for the fast boat ride through the falls to experience the incredible power of the water, and take amazing photos of the place David Attenborough calls one of the greatest natural wonders of the world.
