When we were in Corfu on our cruise stop a few years ago, we signed up for the "Four-Wheel-Drive Safari" excursion through the cruise line. You're given a 4-person Jeep (manual shift) to drive, following the tour director. It's a fantastic way to see the island. Stopped in Sokraki for a short walking tour and light lunch at a taverna, Arkadades (?) for some shopping and baklava, and a scenic overlook for a view of the Paleokastritsa resort area. In total, the trip took about 4 1/2 hours.
