We made a brief trip to Subic Bay in Philippines this Easter. It's quite different from the other
more common destinations like Puerto Galera, Dumaguette, Anilao etc. Mostly wreck dives.
It's easy enough to get there from Manila, so if you've a few days in that area, it's worth
a short trip I think. Here's the link to the trip report and photos, with my thoughts on what to (and not to) do:
