The Island of Sumilon is located off the southeast coast of the Municipality of Oslob, Cebu, and is under the administration of Oslob. The island is about 125 kilometers from Cebu City and separated from the mainland by the Cebu Strait. It is also close to Dumaguete City in the nearby island province of Negros Oriental.
To get to Oslob, you can ride a public bus or a V-hire van from the Cebu South Bus Terminal in Cebu City. The estimated travel time from the city to Oslob is about three hours. The three-hour land trip to Oslob from Cebu City is a scenic ride through the southern coastal towns with fantastic views of the ocean.
From the port of Oslob, there are pump boats or small fast constructs that will bring you to the island. Another route to Sumilon Island is via Dumaguete City since it is also close to the island.
