This trip is definately worth doing (if u'r like me and don't like spending too long on boats) and only 15 euros! We booked with a company which used the smaller boats so were able to stop off at the blue caves and jump off for a swim (do it because the water here is much nicer than at the shipwreck and take a snorkel and mask). Shipwreck beach very crowded until about 1.00 which is when all the big boats go so u get a better photo of the beach going on the small boat because it leaves later.
You have to go to THAT Bar just for the crazyness of it and the music they play is excellent - a mixture of old and new to keep you singing (slurring) along to!
This beach is brilliant if u'r after both water sports and swimming. Unfortunately we were staying in Tsivili so the only way we could get there was to hire a car or moped but its well worth it. We went jet skiing for 30euros - don't go scuba diving bit of a con (we were snorkling in the same place as them and saw exactly the same stuff as them so take a snorkel and mask!! Sun loungers are 4 euros each but nice as they have shades with them. Good bar too.
Go to this so u can get a great view of the beach. Hire u'r own car so u can avoid the coaches which get there midday.
Its an interesting experience! Make sure to take some cards or something they like u 2 b there 3 hours b4 u'r flight goes so theres a lot of waitin around in cramped conditions. If u see a seat grab it!
