Within the city centre must visit, Harpa, Solfar, Hallgrimskirkja. Restaurants to visit are the following: Icelandic Fish and Chips, Bæjarins Beztu (Best hot dogs) and Hamborgara Bullan for its burgers.
Tours to join are Golden Circle and South Coast Tour plus others and of course to visit the Blue Lagoon.
The city is a great location, the food is great and entertainment better then anywhere else as long as you like a good bit of alterative music, I enjoyed the culture and art of this fantastic city.
There are many local tours departing from Reykjavik year round, like tours to the golden circle, blue lagoon, Reykjanes, Snaefellsnes, south iceland etc.
Definitely not to miss the northern lights tours if you go in winter.
There are many beautiful place and landmark around Reykjavik City. Hence, you would love to be there if you like to watch every beautiful scene.
Experience both daytime ahopping and night life here. There are many great restaurants that are defintely the best in the world.
Must visit Harpa,Solfar,
If you like adventures you should go to Reykjavik or Iceland. What an amazing nature and there is so much to see and do.
We stayed for only four nights and we traveled to places and did things all the time, but we could easily have stayed for plenty of more nights and still be busy going to places and try out things.
