Just returned from Iceland. I loved it! We were there for 6 days, stayed in Reykjavik in a VRBO and did three long day trips. Every day felt epic and I was never disappointed.
Day trips:
Snaefellsnes Peninsula. They say that it is like a mini Iceland; you will see everything of Iceland there. Beautiful scenery–glaciers, black beaches, fishing villages, lava fields. Had some delicious fish and chips from a fish and chips truck in Arnasapi.
Golden Circle. We started the day at the Secret Lagoon, smaller and hotter than the Blue Lagoon. Then went to Fridheimar Farm, a tomato farm, for a delicious lunch–Bloody Mary and tomato soup with incredible freshly baked bread. Then off to the incredible sites of the Golden Circle. Be sure to watch the eruption of Strokkur from as close as possible, it is quite amazing. (I don’t know if it is always amazing, but I was expecting a standard eruption, but it was not at all standard!)
Jokulsarlon. Glacier Lagoon. Well worth the long drive. Really otherworldly. Stops along the way have been mentioned above, including Vik. We actually drove straight there, early start because we anticipated crowds. And made our stops on the way back.
We also went to the Blue Lagoon and two city pools in Reykjavik. All different and great.
National Museum of Iceland has an audio tour, which I always like.
Hot dogs are a big thing, there are a couple popular stands in Reykjavik.
I loved reading the blog IHeartReykjavik. I used this as a resource for our big days of driving, lots of suggested stops.
I was really reluctant to return home!
