Magasang Rock Formation, Natural rock formation on Biri Island, Philippines.
Magasang Rock Formation on Biri Island consists of tall limestone cliffs marked by grooves and patterns shaped by constant wave action and wind exposure. The structure varies in height and texture, creating different sections that reveal layers of geological development along the shoreline.
The formation developed over millions of years through geological processes driven by tectonic shifts and continuous water erosion that sculpted the rock surfaces. This slow transformation represents part of the broader geological history that shaped the entire Northern Samar coastline.
Local communities view this formation as a landmark connected to their relationship with the sea and incorporate it into stories passed down through generations. The rock shapes how people navigate and understand the coastal landscape around them.
Visitors should plan their visit around low tide conditions, when more of the formation becomes accessible and safer to explore along the base. Local guides or boat operators know the best times and routes to visit and can help time your trip to the tidal cycle.
During specific tidal conditions, water collects in depressions across the rock surface, creating temporary pools nestled among the eroded stone. These fleeting water features shift and disappear with the tide cycles, offering an element many visitors overlook.
