Hello. We did the Parga-Paxos trip two years ago. It was a long day travelling by bus to Corfu town harbour and then taking the ferry to the seas, so I wouldn´t recommend it for families with small children. My kids were 8 and 13 at then and they loved the trip. We sailed to Gaios, the "capital" of Paxos first. We had some two hours there and had a lovely lunch near the market hall. The weather was much hotter than in SS, but I still would have liked to stay there forever. What a lovely, lazy atmosphere... After Paxos we headed towards Antipaxos crystal clear waters. It was possible to go swimming there if you wanted. Again, some amazing views. Parga was the last stop on our trip. Parga is very popular among Finnish tourists, but in my opinion can never beat Corfu and SS
We had an expensive and delicious lunch there, the marina area was very busy around noon. Probably the best part of this trip was the voyage back to Kerkira harbour; is sat on the front of the boat with my son and we saw dolphins and some colourful fish next to the boat and heard the sea breeze in ou ears.. Yes, I would recommend this day trip. The only drawback was the rough sea between Antipaxos and Parga, if you are going be sure the take some medication (perhaps not ouzo..)
Excuse me my bad English, but feel free to ask further questions..
