"Outer-worldly, exotic, and only a 5-hour flight from New York! Iceland and its ever-changing weather is full of surprises."
I've been to Iceland a handful of times over the years. Every trip has had all sorts of different weather to contend with. Hurricane winds, hail, rain, snow, have all made appearances during my stay in Iceland. I've still yet to drive the ring road and experience outside of Reykjavik which gives me all the more reason to go back. It has been getting increasingly more expensive over the years which is a bit of a bummer. So visit now while it's still (relatively) affordable.
The Blue Lagoon
It's become increasingly more expensive and a bit of a tourist trap, but the Blue Lagoon is still a worthwhile day trip as a means to unwind in my opinion. It lies halfway between the airport and Reykjavik so it's a good place to stop at on your way out of the country. I've been there a few times and when the weather is nice its great, when its hailing, not so great.
Reykjavik has an abundant street art scene if you wander enough.
