If you can't find anyone to take you in their car, you can take public transpo, here's what you gotta do:
1. Take any bus heading to Batangas (bus with the sign board that says "BATANGAS PIER") bus fare is about Php180.00 Travel time is approx. 2.5hours Tell the bus conductor to drop you off in "Bolbok" (intersection going to Bauan/Mabini/Anilao)
2. Get on a Jeepney that goes to Mabini, and tell the jeepney driver to drop you off at the Intersection / Crossing going to Anilao. fare is about Php30.00 Travel time is approx. 30mins
3. From there, get on a tryke going to Anilao port area. tryke fare is about Php20.00 Travel time is approx. 5mins Get off at the tryke station fronting the grocery store on left turn going to Anilao.
4. This is where your negotiation skills will come in handy. If you hire a tryke to bring you to Planetdive, it should be between Php70-100.00(daytime); Things change at night,it could go as high as 200-300. If you are lucky, some jeepney go in Anilao however, it is very rare so i don't advise waiting for a jeepney but instead try to negotiate with the tryke drivers.
Been there, done that. =) Good luck and dive safe!
