Oh dear Hamish! What were you expecting? For a whole $5? Ginns pools are what are known as ‘authentic’ which means they aren’t artificially sanitised to look like an everyday swimming pool. All posh and tiled – and boring. This is the real deal, with minerals bubbling up from the geothermal reservoir which is 1500 metres down under a rock cap in the Ngawha geothermal field which is 50 sq km in size. The walls of the pools are old kauri, completely authentic and mostly original. Hamish, you came and have a free one next time. Bring a friend or three for free too!
