Day 1
Iconic sights & old town
Hit the headline sights early before the crowds, then ease into Reykjavik's café culture for the afternoon.
Morning
Hallgrímskirkja
The landmark concrete church inspired by Iceland's basalt columns. Take the elevator to the tower for the city view.
Afternoon
Blue Lagoon
The famous geothermal spa. Touristy but worth it — book the earliest morning slot to beat the crowds. Stop on your way to or from the airport.
Evening
Golden Circle day trip
Þingvellir National Park (where the tectonic plates split), Geysir (the original geyser), Gullfoss (the waterfall). One full day, do it yourself by rental car.
