Osiao is one of two hamlets that can only be reached by charting (often rough) waters. Populated by around 300 families, this tiny, remote barangay is nevertheless big in possibilities. It is here where tiger grass grows in wild abandon. At harvest time, the grass is woven into brooms, which then find their way to Baguio and are eventually sold as “Baguio” brooms.
In Osiao, one can find Lake Danao, whose emerald waters mirror the surrounding mountains. As one of the hosts of the PNOC, the barangay provides natural energy that powers up the turbines of the National Power Corporation.
