The Newly Recognized Queen's Bath is a unique tide pool on the island of Kauaʻi, Hawaii. The pool is a sinkhole surrounded by igneous rock. It is located on the north shore of Kauaʻi in the town of Princeville, at 22°13′44.9″N 159°29′15.0″W. Small fish and tiny sea life also live in the tide pool, such as Hawaiʻian sea urchins, angelfish and the so-called "ghost fish".The original "Queen's Bath" was located in Kalapana on the Big Island of Hawaiʻi.
It was formed after a lava tube collapsed and filled with fresh water supplied by natural springs. In ancient times only the Aliʻi were permitted entry to the sacred waters. In 1983 Kilauea Volcano erupted and in 1987 the original site was destroyed by lava flow.
