Queens Bath - Kauai, HawaiiQueen's Bath - 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 near the town of Princeville. 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.
