Agusan del Sur

Province Overview

The Largest Province in Mindanao

Agusan del Sur is the largest province in Caraga and the entire island of Mindanao, covering over 10,314 km² of tropical forest, wetland, river valleys, and highland terrain. Its vast interior remains among the least developed and most ecologically rich territories in the Philippines.

The centrepiece of the province is the Agusan Marsh Wildlife Sanctuary — a sprawling 19,200-hectare Ramsar wetland that shelters the critically endangered Philippine freshwater crocodile, over 200 bird species, and the floating-island communities of the Manobo people who have lived on the marsh for generations.

The province is home to five major indigenous groups — the Manobo, Banwaon, Mamanwa, Higaonon, and Talaandig — whose cultural heritage spans millennia. Prosperidad is the provincial capital; Bayugan City is the province's main commercial hub.

Agusan Marsh Wildlife Sanctuary

One of the most ecologically significant wetlands in Southeast Asia. This 19,200-hectare Ramsar-listed sanctuary is a labyrinth of lakes, floating islands, reed beds, and waterways — home to the critically endangered Philippine freshwater crocodile, over 200 bird species, and the Manobo people who live on floating reed platforms called basey. Guided boat tours reveal extraordinary wildlife and a way of life found nowhere else on earth.

Manobo Floating Reed Communities

Among the most remarkable human settlements in the world — Manobo communities in the Agusan Marsh have lived for generations on floating reed islands woven from dense aquatic vegetation. These basey drift naturally with the water levels across seasons. Respectful visits arranged through the Bunawan LGU allow travellers to witness this extraordinary way of life, observe traditional crafts, and connect with a culture uniquely adapted to life on the water.

4th Largest Lake in PH Map

Lake Mainit

The fourth-largest lake in the Philippines, straddling the boundary of Agusan del Sur and Surigao del Norte. Fed by geothermal springs, the lake is famous for its warm, crystal-clear waters surrounded by forested slopes and its unique endemic sardine species found nowhere else in the world. Boat tours offer exceptional scenery and birdwatching, while traditional fishing communities ring the shoreline practicing centuries-old net fishing.

Forest Waterfalls Map

Sibagat and Veruela Falls

The interior municipalities of Sibagat and Veruela are threaded with rivers tumbling off the Diwata Mountain Range, creating a series of forest waterfalls largely unknown to outsiders. These cascades drop through old-growth dipterocarp forest into clear rock pools ideal for swimming. Community eco-guides from local Manobo villages lead visitors through forest trails, and the surrounding forest shelters Philippine eagles and dozens of endemic bird species.

Mountain Range Map

Diwata Mountain Range

The Diwata Range forms the rugged eastern spine of Agusan del Sur, rising to over 2,000 metres and sheltering some of the largest remaining tracts of old-growth rainforest in Mindanao. Trekking expeditions depart from Loreto and Esperanza guided by Banwaon and Manobo trackers. The range shelters Philippine eagles, tarsiers, hornbills, and dozens of endemic flora species in a wilderness almost entirely free from outside visitation.
