Depart Kalbarri Airport for a once-in-a-lifetime opportunity on this 45-minute flight to see the Pink Lake at Hutt Lagoon near Port Gregory. Fly over the Kalbarri town and low along the beachfront before climbing to cliff height to view the spectacular coastal cliffs with their red sedimentary rock colours. Continue past the surfing beach, Red Bluff and Rainbow Valley, where rainbows may be seen in the sea mist due to sands and silts containing an assortment of minerals that have layered, compacted and weathered to form this spectrum in stone. Next, view a series of connecting gorges, including the natural bridge before flying past the white sandy beaches of Lucky Bay and over the Pink Lake. The lake contains a pink hue created by the presence of carotenoid-producing algae Dunaliella salina, a source of ß-carotene, a food-colouring agent and a source of vitamin A. The Pink Lake is approximately 70 square kilometres with most of it lying a few metres below sea level and fed by marine waters through springs. After circling the lake head back to the airport over the National Park.
