Just outside Paris (a half hour bike ride from the Eiffel Tower) you'll find the quirky island of Ile Saint Germain. It's a cute little hodgepodge of architectural styles, reminiscent of a fishing-village-meets-60s-style, with a good dose of community charm thrown in.
Wandering these streets provides endless artistic inspiration, with secrets to discover at every turn. Look for the mosaic guide to water birds by the south bank of the island, find the 50s-style mechanics servicing vintage cars, visit the cute fruit and vegetable shops and discover the community garden.
If you want to stay the night, there are houseboats on the opposite bank offering lodging for adventurous guests.
