A group of three islands (Gaspar, Melchor, and Baltazar) off the southern coast of Marinduque, each offering pristine coral reefs, white sand beaches, and crystal-clear waters. Named after the Three Kings, the islands are a marine sanctuary with excellent snorkeling and diving. The islands' isolation has preserved their unspoiled beauty and rich marine biodiversity.
