*jut703 - That's the one! Thanks.

Okay, so your description to Camaya Coast tells me about another 15kms from Mariveles, just the 30km from there onwards now.

There's a video of someone running the route in a Hi-Lux, but that's from 2010 or so. There were a couple of washouts that they made it through, but it's knowing whether they've been repaired or had several more years of rains and storms to really kill the road.

Another possibility is to run Balanga - Bagac on the way over, see if I can pick up some local knowledge about the Mariveles route when I'm there and maybe do the return route that way

Thanks again for the information. Appreciated.
