Rob: Depending on where you're coming from, PEI has a really strange sense of scale. From Cavendish (north side of the island) to Charlottetown (south side of the island) is about 1/2 hour. The entire island is: 5,683.56 km2 (2,194.43 sq mi) - by comparison, the field study I used to run in eastern Ontario was nearly eight times that size. Personally I like the north shore and also the west arm. You can drive around the entire west arm in two days. Take a side trip to Lennox Island if you like and visit the gallery there. It depends on what you're looking for. Red dirt - everywhere. City - basically Charlottetown, although there are some interesting older buildings there as well. Anne of Green Gables house - north shore. Great coastline - just about everywhere. It's been a few years since I was last there (2002), and that was about a decade or so later than the previous visit. In those ten years I noticed that a lot of the island seemed to have grown in quite a bit. Less open farmland, more trees.
