For a lesser known place to go and relax, there is a rocky area by the sea in the old town. Walk up past the old school (apparently an old school anyway) and over the car park and follow a little path down to the sea. There you can sunbathe on the rocks, swim in the sea or jump/dive off the rocks (some are quite high!) if you are feeling a little more adventurous. The sea is quite deep here and can be a little rough at times so make sure you take this into consideration if you are not a fairly strong swimmer.
