Hi Zippercmos:
Getting to Subic:
Public Transport. Buses leave the Victory Liner station in Pasay from early am. Catch the 4 or 5am bus to get to Subic in time for diving. Cost is approx 230php You'll arrive around 8.30-9.30am in Olongapo bus station. Quick trike trip from there (about 150php).
Private Car. Can private hire/charter a taxi. Either negotiate with taxi in Manila, or drop me a pm for a reliable driver. Cost is about $100 each way. It's expensive, but they have to pay tolls along the expressway. Trip takes 2-3 hours (depending on Manila traffic) so you need to leave early.
Subic Diving: I can arrange 3 dive trips with guide for 3500php. Kit hire 750php per day, if reqd. Either with myself or another very experience instructor here. Not sure of my weekend schedule at the moment, am in the middle of tec course this week. Dives are mostly wrecks, but shallow and calm for beginners. There's also several decent reefs and artificial reefs that are cool for photo etc. Vis is really nice at the moment. 12m+ on USS NY on Sunday. 16m+ on LST. San Quentin and Barges like crystal. If interested, let me know your preferences and comfort zone - we always tailor the dive schedule for customers.
