[6] The "Bien Unido Double Barrier Reef Marine Park" is the first underwater pilgrimage in Asia, established in 2012.

In 1935, two sitios in northern Trinidad were united into one barangay under an executive order and was given the name Bien Unido.

[10][11] Bien Unido is located in the northern part of the island province of Bohol.

Currently, only Barangays Bilangbilangan Diot and Hingotanan East are classified as rural and the rest are urban.

The farmed seaweeds are used as essential ingredient for gel capsules, soap, toothpaste, slippers and other plastic wares.

Bien Unido can also be reached directly from Cebu City through Pasil-Suba fish port via pump boat in more than 3 hours.
