Beach Walking the Llyn Peninsula

"Look," Eileen says, pointing at the map. "You can walk the beach all the way to Pwllheli if the tide is out."

We're standing on the beach of Abersoch, the main surf town of the Llyn Peninsula. We've treated ourselves to breakfast out, so now we're feeling ambitious. We can see down to the rocky headland, and it looks passable at this tide. I think the tide is going out.

"But what about the car?" We've paid for three hours of parking, but Pwllheli is far enough away that we won't want to walk back.
