To those people coming from the north, and is familiar to SM San Fernando.  That's your starting point go straight up ahead past Mexico.  There are also some Jeepneys plying the San Fernando Candaba route (Mc Arthur Hway intersection San Fernando Pampanga and I think is now relocated in the Main terminal Gapan rd.)  There is  also the San Simon (NLEX exit) way from Apalit if your coming from Bulacan (Malolos, Bocaue, Calumpit) or Mc Arthur Hway.  If your from Manila Take a bus going to Arayat from Monumento. 
Don't hesitate to ask for directions when you get there as the people there are very friendly and very much promoting the ornamental fish and tilapia Agri-business.
