Queen's Bath is a unique tide pool on the island of Kauai, Hawaii. The pool is a sinkhole surrounded by igneous rock. It is located on the north shore of Kauai near the town of Princeville, at 22.230, -159.486. The swimming area is accessible via a short trail. During the winter when wave activity is violent, it is considered dangerous. In small surf—usually in the summer—the water in the pool is calm. Small fish and tiny sea life also live in the tide pool. The original "Queen's Bath" was located in Kalapana on the Big Island of Hawaii. It was formed after a lava tube collapsed and filled with fresh water supplied by natural springs. In ancient times only the Alii (Royalty) were permitted entry to the sacred waters. In 1983 Kilauea Volcano erupted and in 1987 the original site was destroyed by lava flow. Only after the original site on the Big Island of Hawaii was destroyed did the location on Kauai become better known as "Queen's Bath".
