Sipayuk Islet is the last islet of Bongao that serves as the border of Bongao and Languyan Municipality. It is under the jurisdiction of Barangay Silubbog of the capital municipality – Bongao. Silubbog is the last barangay of Bongao to the North - the adjacent islet of Sipayuk. Indeed it is really the border of Bongao and Languyan because of the fact that getting here from Bongao Aquada Bay/Chinese Pier will take you 29 minutes via speedboat (around 2 hours via motor launch/lantsa). The same calculation when you ride a speed boat from Languyan Proper (I really used stopwatch!!!). Sipayuk Islet is not so famous to Tawi-Tawians, only to the people of Languyan. This Islet is currently inhabited by about 15-20 households whose sources of livelihood depend on fishing and sea weeds farming.

Sipayuk Islet never fails to mesmerize bloggers and photographers every time they passed by to Languyan municipality.
