From Manila to Subic, you can take a cheap way by using Vitory Liner from Palay EDSA to Olongapo (215 Peso per person). Many local Filipino use the Vitory Liner to go home. The bus terminal are full of person on my arrival day in Manila (May be it was Saturday). The termainl is hot and a long queue to buy tickets. Upone arrival of Olongapo, then followed by motor tri-cycle to your resort (200-250 Peso per car). Overall it takes 4 hr from Manila to my hotel. Another expensive but luxury way is to ask you hotel to arrange a airport pickup which costs 4000-4500 Peso per car. I think the later is better if you have 3-4 birders to share the fare.
Renting a car in subic is a must to birder (or you have you own transportation) as the area is too large for walking. Car rent: CATCOR RENT A CAR (047)224-1723 or email: catcor_rentacar@yahoo.com. Discounted price for 5 days in Subic: 10000 Peso for a Toyota 1600cc private car which is quite reasonable to me.
I would suggest birders to stay at the Crown Peak resorts (I stayed at TIARA hotel: 1500 peso per night) as the area around is easy to spot the Blue-naped Parrot and Some philipine owls. The Crown Peak is located at the forest edge and it took 15-20 mins of driving to any birding spots of the subic forest. The area is also quiet than the Baloy beach but with less restaurants and resorts available: one restaurant (The Chef E Resto is good) and one 24-hr 7-11 like shop available in the peak area.
The best birding sites is the Nabasan Trail (the road to IDESS Maritime Centre) where we can see the Green Racquet-tail every morning on the same tree. Close to the road end of Nabasan Trail going west and heading to the Ocean Adventure direction, there is a good road where is easy to hear the Shama.
Wild bird club of the Philippines also provides a lot of trip reports on subic. Their web site: http://www.birdwatch.ph/. You may contact them to see any members can accompany you in your holiday. I have met the founder of the club and a member, they are really very nice people.
79 species of birds were encountered of which 37 are Philippine endemic:
