Of course there are many beautiful resorts in the south but I still prefere the small resorts, Not the ultimate Greek inland villages, but the small quiet resorts, often where many Greeks visit. I can well understand the reps in Casiopi selling the bus trips around the north or Corfu town. The views around the north in places like Palio and the north east coast road from a coach are amazing. There are similar views in the south in places like Scala but I don't think it possible to get a coach along this road. If I were to organise a bus trip anywhere I would take people to the town hall above Kalami, bella vista above Palio and then take them down the middle of the island down the road that goes past the quarries and then through Skripero back to the town. The views are amazing as you can see the sea on both sides of the island at this point. If I could get the coach up there and be able to turn it round I would go to Afrionis on the west which has no beach as it is too high above the sea as I believe this is one of the best villages on the island and a great place to drop every off for a two hour lunch.
Trips to Corfu town can be booked anywhere on the island and are very popular for shopping trips. Just have a coffee on the Liston and people watch. It may cost a few quid but it's well worth it.
