There is a beach frontage road from behind Pedors (where the gate is) that intersects to the road running past La Hoste. Rough but drivable. Lots of parking along there.
Some of the parking behind Pedros is out in the bushes so I have not been to comfortable there. Along the frontage road further up the beach it is all pretty open.
You may also want to look at Palm Beach where the access road is north of El Rancho down the hill(did I get that right?) Much less congested on multi-cruise ship days.
Surf, tho, up that way can be rougher than closer to Pedros.
