The Cardwell Spa Pool is a naturally-fed seasonal creek. Located in the coastal town of Cardwell, just 2.5 hours south of Cairns, the pools are somewhat of a geological wonder. Thanks to the chemistry of the rocks and water, the colour can vary from a bright, baby blue to a more milky-blue colour depending on the time of day and available sunlight.
May to September is the best time to visit the pool, as rains during the summer months will usually flush the creek out, returning it to normal levels from around March each year....
