Change the time on your watch/phone/sundial/wind-up alarm clock. Spain is one hour ahead, so assuming you wake up at the same hour as the day before you will find things to be darker than usual.
From the ferry terminal in Camposancos you can choose to take an alternative route that circumnavigates the peninsula to the south, adding about 4km to the journey but adding some great views.
Otherwise turn left from the ferry terminal to follow the water a short distance to the first road, turning right and uphill on the Camino del Palomar. Note that this is not the road that is marked A Guarda 2km. That road, marked red on the map, is a possibility though not the camino.
The Camino del Palomar continues more or less straight uphill, turning only to pass around a large apartment block. At the top, it first crosses the road before turning left. A dozen meters on keep to the right along a smaller road, at which point you are heading south rather unnaturally. The camino turns itself around by turning right and then right again to follow a series of roads and trails around the Monte de Santa Trega.
It eventually returns to the Paseo de Portugal road mentioned above and turns left into town. Entering this way means that you will stay at the upper half of the town, and a few variations exist which allow you to descend and then ascend.
