To end of camino153.2
From the Area Grande beach keep to your left and through the car park. Where the car park ends the path narrows, and a smaller trail to your left presents itself. Follow it along the coast.
About 1.2km later the camino turns right at a large house, rising uphill to the main road but turning left just before reaching it. The idea here is to again keep off the busy road by means of a few side roads, twisting and turning a bit but eventually returning to the main road once more.
When it does so you can follow along a dedicated bike/hike path. It will pass a car park/lookout point before turning left off the road and then right again to parallel the road all the way into Portocelos.
