Occasionally and more so in winter, the water can have a small swell so some small wave riding is possible too.
I'm still learning to skimboard myself and I have to say its a lot of fun, a cross between surfing and skateboarding. I plan to get around the island and take a look at various beaches and I will be reporting here in any spots that look good for skimboarding on Bantayan Island. So far I have only tried it around the south west side at Santa Fe where it is mainly flat on the white sand beaches.
I have created a video of my experience of learning to skimboard on an old wooden skimboard.
