Of the scattering of 123 limestone islets and islands shrouded in greenery, some are craggy and cliff-y, and others have pleasant stretches of beach (though litter is a problem on the most popular islands), calm waters for snorkelling, caves to explore and plenty of avian life. The only three islands with facilities are Quezon Island, Governor’s Island and Children’s Island; the rest are uninhabited and you can have them to yourself, as domestic tourists make a beeline for the former.
The beaches on Quezon, Governor's and Children's Islands are nothing special, although Governor’s Island has a nice lookout point and the calm, shallow waters surrounding Children’s Island are ideal for children.
One of the remotest islands, Cathedral Island is known for its variety of seabirds; on Marcos Island you can practise cliff-diving from a 20m rock tower; Cuenco Island is bisected by a cave that passes right through it and tiny Martha is picture-perfect beautiful, the beach between the two tiny islets only reachable during high tide.
