Hire a motorbike, as the island is too large to get about by foot and public transport is limited.
On arriving you will be mobbed by touts, it is best to walk past them into town, a 500m walk.
It is a very laid back place, not busy.
Some nice beaches but, no easy to swim coral reef that I found close. The porus island slops off to sand and sea grass, is home to some 120,000 people and million(s) of chickens. That may explain why so much sea grass washes up after storms.
Typhoon Yolanda came through and over Bantayan Island making a big mess.
Historical walking tracks for every level of fitness, to every part of Cebu!
So many close places to see and explore.
