My husband, myself, and our two daugthers (23, 25) are traveling to Iceland for the first time on August 29 - September 4. I know it is important to wear layers, but trying to figure out how warm that outer layer really needs to be. If we have a base layer covered with pants and some kind of zip-up with that be sufficient with a raincoat if needed or do we need to bring a winter coat? Our itinerary is as follows if that is helpful for advice.
- Arrive 9am - Blue Lagoon and explore Reykjavik
- 2-day tour to South Coast (Glacier Lagoon and Glacier hike)
- Snaefellsnes day tour
- Landmannalaugar day tour
- Golden Circle Tour day tour
- Explore Reykjavik and depart 6pm
Thanks in advance for your help!
