Located in barangay Kayapa in Bakun, this is a waterfall being eyed as a potential tourist destination. We tried visiting this sometime in 2019 but it wasn't yet open for trekkers. The name of the waterfall is in the Kankana-ey language. Beey is house, manok is chicken. So it roughly translates to "chicken house" or "house of the chicken".
Should the town decide to open the site for trekkers, it will add to the several waterfalls in the area that already accepts visitors. Most of these waterfalls are within barangay Poblacion - Tekip Falls, Mangta Falls, Pattan Falls, Pikaw Falls, and Sakup Falls.
Also south of barangay Sinacbat is Dalingaoan Falls which some people refer to as Tres Marias Falls. This is actually a series of several waterfalls with 3 major drops. Thus explains the "Tres Marias" nickname.
Barangays Poblacion, Sinacbat, and Kayapa are adjacent to each other. This means a trekker can visit all these waterfall sites within a couple of days.
Even better, hiking destinations like Mt. Kabunian, Mt. Lubo, and Mt. Tenglawan are also within the same vicinity. Thus, a trekker can come up with a well-planned itinerary that can shoot at all these sites with one go.
