We thought this place was excellent, really recommend trying the waterskiing. However prices were a little steep for the amount of time you spent on each activity, but still worth it. There is a free bus that picks you up from laganas at 10.00am and returns again at 5.00pm.
We thought this was great, although may seem a lot 25 euros for 2 hours, definately worth the money. We even got to go to a private beach!! I can't remember the name of the centre but if you look on the adverts for horseriding it is the one with the horse stood on back legs!! The instructor is called Nicholas and was very helpful.They even pick you up and take you back for free. Very highly recommended.
We booked our trip through Dionissis tours and highly recommend them. Really good boat, good food and good guide. We had 3 swim stops (reommend taking snorkel and fins so you can swim through the blue caves). The trip only cost 15 euros and was definatly worth eveery penny. The english couple who run the company from Laganas are very helpful and honest. Excellent day out.
