The Golden Circle is a roughly 300 km loop from Reykjavik covering three major sites — Þingvellir National Park, the Geysir geothermal area, and Gullfoss waterfall — and it’s easily done in a single day.
Þingvellir National Park
Þingvellir is both a geological and historical site: it sits on the rift valley where the North American and Eurasian tectonic plates are pulling apart, and it’s where Iceland’s parliament, the Alþingi, was founded in 930 AD. Walk the main path through the rift for views over the valley and Þingvallavatn, Iceland’s largest natural lake.
Geysir Geothermal Area
The Geysir area gave English the word “geyser.” The original Geysir rarely erupts now, but the neighboring Strokkur erupts every few minutes, sending water up to 20 meters into the air. Stick to the marked paths — the ground around the hot springs is genuinely dangerous.
Gullfoss
Gullfoss (“Golden Falls”) drops in two stages into a rugged canyon. There are upper and lower viewing platforms; the lower one gets you closer to the spray, while the upper one gives the better overview shot.
Worth adding on
If you have extra time, consider Kerið crater lake (a small fee applies), Friðheimar tomato farm for lunch, or the Secret Lagoon near Flúðir — a less crowded geothermal bath than the Blue Lagoon.
