Bantayan Island is flat and compact, making it easy to get around. The main options are tricycle (the ubiquitous Philippine motorbike-and-sidecar combination), habal-habal (motorbike taxi), or renting your own motorbike or bicycle.
Renting a motorbike is the most practical option for exploring beyond Santa Fe — several places in the beach area rent them by the day for modest prices. The roads are in reasonable condition and traffic is light. The island is small enough that the 12 km between Santa Fe and the town of Bantayan takes about 20 minutes, and you can circuit the entire island in a few hours.
Bangka (outrigger boat) is the transport for the offshore islets. Boat rentals are arranged directly from the beach at Santa Fe and rates are typically negotiated per trip.
