We are planning to visit Iceland for 8 days, we will be traveling with our then 9 months old son - we want to see few things that are really must do's - don't have to cram everything in 8 days. Probably will do 3 days in Rek. and then what should we do for the remaining 5 days? Suggestions are welcome. Thank you.
I don't know what you would consider "doable" with a young child but pick up a copy of Lonely Planet Iceland and check out some itineraries. Eight days may be too short to drive the entire Ring Road around the country...but there are other towns to see, including Akureyri (short flight or longer drive). I did multiple tours through Reykjavik Excursions but I don't know their policies re: small kids. By the way, you could just spend 8 days in Reykjavik and not get bored if you take it slow and stroll around, see the museums, check out nearby fishing towns (one starts with an "H", etc).
I haven't been to Iceland yet but will spend 3 days there this summer as part of a Germany/France vacation. If I had eight days I would spend 2 days sighseeing in Reykjavik, 1 day for the Golden Circle tour and then head north for the remaining 5 days and split them between visiting the Snaefellsness Peninsula and the Western Fjord region. Or you could head south towards Vik and beyond after seeing Reykjavik. If you don't want to rent a car you can use Reykjavik as a base and take several sightseeing tours. This way you can split up museum/shopping/relaxing days to prevent overload and might even be able to the better weather days for sightseeing tours and outdoor activities. Purchase several guidebooks to get a variety of opinions and get a map so you can see what your driving options are and what type of roads you will encounter. For some things that interest you, you might need to rent a jeep. Also, do an Icleand search on this website and other travel websites such as Fodors, Frommers and Trip Advisor.
