I went to Menorca in 2013 the second island of the Balears (Spain), I was surprised for the beaches, I knew would be nice, because I had already been in Mallorca (the biggest island), in this occasion I went a few days to disconnect a little bit, and in fact I did, it was at the beginning of November and even like that I could have a bath even the water was cold, I recommend if you go to Menorca to hire a car because it is easier to move in the island,  some of their small beaches (cales) have difficult access so you have to go walk but believe is worth it.
