We are planning to travel to Iceland for the month of July this year. We have three kids (13, 8, and 5) who travel frequently with us for longer periods, and I'm wondering if anyone can give us some specifics about daily things for the kids to do in the city center/downtown area. We generally look for parks, playgrounds, swimming, beaches, etc. Fun, daily (primarily outdoor) activities that we can walk to, where they can explore and be kids. I would also appreciate advice on places to take them by bus in other parts of the city for fun (amusement parks, zoos, etc.). Any great shopping or restaurants we shouldn't miss? We are excited to get to know Reykjavik this year - Thank you!
