Camera? Phrase book? Swimsuit for spontaneous plunges into the inviting ocean? All candidates for a daypack. I use a tank bag (that also has a handy transparent map pocket) but a rucksack or tailpack can work just as well. Remember you won't be riding ALL the time Even if you're planning to ride all day, every day, you won't want to have dinner in a one-piece leather suit will you? If it's sunny you'll probably want a dress or shorts, maybe a sunhat? Sunscreen? Motorcycle boots are not great for walking around, especially if it's warm. Take trainers or sandals or something.
