I'm wondering if anyone can give me any "must-sees" for Shikoku... I'm looking for beautiful, quirky, off-the-beaten track destinations, although I'd also like to visit places like Dogo Onsen and Mount Ishizuchi as well. I think I'll be on the island for 5-10 days and am wondering how much of the island I would be able to see in that time.

I'm thinking of flying into Matsuyama from Tokyo and then after touring Shikoku I want to take a ferry to Hiroshima, which leads me to my second question- has anyone done this? Would there be a better way to get between the two cities?

Thank you!
