I agree that the diving is great in both places, but I would tip the scale toward Dumaguete if I had to choose one, primarily because of Apo Island and because of the sanctuaries that are more protected than some of the dive sites in PG. From the standpoint of convenience, PG is a lot closer to Manila and it is true that the nightlife in PG is better. The Point Bar near Asia Divers is fun after a long day’s diving. Watch out for that bloody bell though! There are superb restaurants in PG also, giving you a lot more options.
Unfortunately, the bloody Red Sun resort is now finished. It looks as if a cruise ship has slammed into the side of the island and left rooms for people to sleep in. From my standpoint, the view in Dumaguete is far superior, especially at sunset.
What tips the scale for me also is that there are other things to do in Dumaguete, such as hikes and other sporting activities. And though it is a strange dive (one I wouldn’t flock to for its own merit), I recommend the Bacong pier dive, which you have to do when there isn’t a huge ship docked to get in the way. There are creatures galore on those haphazard spires holding the piers up, and if you are lucky a smaller ship might be in to give you one heck of an interesting silhouette against a backdrop of light and fish. It was very nice in an industrialized kind of way. I saw so many sea horses there and frog fish, I was amazed that they’d opted for such a place to put up shop. Again, not worth it on its own but it is a nice novelty.
Also, you can get a boat ride out to Sigijor (roughly the same time it would take you to get to the washing machine in PG). There are nice dive sites there also, and if you are inclined, do the drive up to the “healers” living in the hills nearby, you can get an interesting view of Filipino culture and mythology. There are human beings living there that are older than Adam, so they claim.
For what it is worth, Anilao represents a great compromise between the two. It is the same distance out of Manila (not including the banka ride needed to get to PG), and there are very nice dive sites scattered around the point. It is just as easy to get to the washing machine, and you will have access to Sombero Island and Beatrice, two fantastic dives!
Still Dumeguete beats them both by my estimation. No matter what you choose though, you are in for a treat.
After all that, I’m off to PG this weekend, not to Dumaguete. I’d stay at El Dorado in Dumaguete as well. I think their food is better than Atlantis. Just an observation.
Hope that helps.
Cheers!
