It is a beautiful port, very quiet, with a narrow and irregular road that drives very well. Both aspects are worth it, although they are very different. I like the east side better. It is a perfect alternative to climb the Col de Soulor, avoiding the busy passage through Argelès and the first part of the climb to Soulor.
