Bluewater Sumilon Island Resort is located on tranquil Sumilon Island. The Island remains as one of Cebu’s best kept secrets and is found on the southeastern tip of the mainland. It is 125 kilometers from Cebu City and is in close proximity to Dumaguete. The island has an area of 24 hectares and is surrounded by crystal clear waters with varying aquamarine hues. It is the first marine protected area in the Philippines and was made a fish sanctuary in 1974 under the guidance of Siliman University Marine Reserve. During dives, one will find varied marine species and even occasional sightings of black tip sharks. Pristine white sand beaches are situated in different areas in Sumilon.

Its sandbar is well known for its changing shapes and shifting locations around the island, depending on the season. On the island, there is a natural lagoon teeming with high mangroves. There are also natural caves where fishermen used to seek refuge. On the southside, a lighthouse rests on a protected tree park. Beside it is a Baluarte, a historical watchtower built as part of a warning system to thwart slavers and marauders in the 19th century.
