We did this trip with Focus Tours. It was very good value, £6 each including lunch. You board on Olu Deniz beach at 10.30. Do be warned though this can be tricky even if you're fit as the waves move the walkway that you need to get on, the guys do give you some help though. It was a very relaxing and scenic trip which stopped 6 times for you to swim or go on the pebble beach. Although they call it six islands, I think it is 6 beaches! There was plenty of space on the top deck to sunbath, although we stayed below as my husband gets sea sick ! A tip if you are a sufferer - stay below and sit as near to the middle as you can, it's more stable. You arrive back about 6, again be careful getting off the boat, it is as precarious as getting on! Great trip though!
