A visit to Reykjavik offers a lot -- from the iconic Hallgrimskirkja church to the cool Perlan museum to the Icelandic Punk Museum (in an old public bathroom). And you can head outside the city to explore Iceland's natural wonders. Traverse the black sand of Reynisfjara Beach. Relax in the geothermal spa at Blue Lagoon. See a crazy amount of waterfalls. And top off your Iceland vacation with a hike to Fagradalsfjall Volcano.
