What a day. Well worth the very cheap price for this trip. Started at 9.00am and finished at 7.00pm. For a whole day trip you couldnt beat 30 euros per person anywhere in the world. Because Milos is such a geological wonderland, the only real way to see it properly is by a round the island boat trip, and Captain Yiangos is a very professional operator.We swam through caves and through blue crystal clear water. There were snorkles and goggles free of charge on the boat. What more can you want... do yourself a favour and take the trip, you'll thoroughly enjoy the day.
