Lake Hillier, famed for its vivid pink waters, is a remote natural wonder best accessed via scenic flights from Esperance, Western Australia, offering unparalleled aerial views. Due to its location on Middle Island, direct land access is generally restricted, making guided scenic flights or boat charters the only practical options; solo visits to the lake itself are not feasible. Flights are weather-dependent but operate year-round, with the lake's iconic pink hue remaining constant. Expect costs for a scenic flight tour, often encompassing the wider Recherche Archipelago, to range approximately from AUD 300-500+ per person, with the typical duration of such tours being 1-2 hours in the air. Visitors should be aware that swimming in or approaching the lake shore is not permitted, and the most spectacular views are undeniably from above.
