Abatan River is one of the three main rivers in the province that traverses through the towns of Catigbian, Antequera, Balilihan, Maribojoc and Cortes. It covers about 400 hectares with the river opening up to an estuary that consists of mixed mangrove and nipa swamp. In 2008, a community tour along the river was initiated that generate much needed income for the farmers and fisherfolks living along the river. The activity also instills to the community the importance of preserving the environment and conservation of cultural heritage. To date, the community has added firefly watching tour to their activities offered.
