Lovely islands and totally worth a visit. It would be benifical to have a car to explore various places.
There are plenty of hidden villages fillled with wonderful cafes and resturants. Henningsvar it by far the best of all. However, be aware of the local stock fish drying in the spring. You'll find the villages full (10,000+) of A frame of drying, headless fish. It is smelly but don't let it put you off.
