Hi Phil. Did the boat trip about two years ago, it was great, a bit like the ferry in 'My family and other animals', if you remember the film. Pegasus, usually operates from San Stefanos, but lately from Paelio due to silting-up of the harbour. Last year they were dredging the San Stef harbour, so with any luck the service will be back there this year.
Pegasus is quite a large ferry with a fully enclosed seating area like a very large bus, there is a 'goods' area at the stern, almost anything is transported to the islands, fuel, gas, fruit and veg etc. There is a raised observation area near the front either side of the wheel-house, and an 'outside' seating area at the stern next to the produce. You need to choose the day well, as the sea can be very choppy! It was quite calm the day I went and I thoroughly enjoyed it. There are two time tables for the service, winter and summer, times and destinations vary. I went on the summer service and had the choice of landing and waiting for the boat to come back from the other islands or staying on-board and seeing them all. I stayed on. Amazing sea-scapes and stunning scenery.
There is no need to book, find out the times and days of departure, when I went it was 10.00hrs. returned about 16.00hrs., Dorita from the Bardis Hotel where I stay dropped me off in the car. You can pay on the boat, around €10. A great day out for very little!
Martin.
