Subic Bay is the site of a former US Naval Base, the largest in the World. The bay itself is not the pristine waters of popular dive sites in the region, but the water temp at depth is surprisingly warm. I visited on a ship and took a day of port time to dive.

The Dive company was called Scuba Shack, and it was quite cheap, with free gear. The gear was old, but functional. Their DM was wonderful and took us through a great pre-dive brief. All dive sites are located nearby, so its just a boston whaler ride out. There was no one on the wrecks, so we had them too ourselves. The dives are at about 90-100 feet. The best was the USS New York, which was scuttled during WWII, to prevent its capture by the Japanese.

There isn't much to do in the surrounding area, though its one of the few places where the exchange rate is still wonderful. Also, its not an easy place to reach, but if you have the time, you can see a multitude of amazing wrecks that are rarely visited.
