IF commute, its just one ride...
from Ayala/Buendia, look for FX na may signboard that says "Angono/Floodway" or "Binangonan/Floodway"....just tell the driver to get you off at Rainforest (sa harap ka mismo ibababa)...

bale eto ung route nya...

Ayala/Buendia-Kalayaan-C5

Along C5, Turn right na sa EAgle Street (just fronting SM Pasig) - straight ahead towards Sandoval Bridge - right to Antonio Ave (going left is towards Rosario) - then left at Stela Maris Ave - left to PAsig Blvd Extn (Tramo) then immediately turn right to F.Legaspi direcho lang po..Rainforest Park & Resort should be on your right, just before going up the LEgaspi Bridge.

Adjacent landmarks are Pasig City General Hospital, Rizal Tech Univ (RTU)

HTH!
