Private Golden Circle Day Trip: Secret Lagoon & Friðheimar Greenhouse
Select participants and date
A low, sea-bright sun slides across Reykjavík’s harbor as a minivan pulls away—today the city’s tidy grid gives way to lava fields, farm fences and the slow geometry of Iceland’s Golden Circle. The air changes in stages: urban salt, then the iron-mineral breath of pumice, then the sulfur-sweet steam that announces geothermal country. By midmorning the van eases into Þingvellir National Park and the guide opens a door on both history and geology: a rift valley where the North American and Eurasian plates pull apart, where Vikings raised the Alþingi in 930 AD and argued law beneath flat slabs of basalt.

Adventure Tips
Dress in layers
Weather changes fast—windproof, waterproof outerwear over insulating mid-layers keeps you comfortable during canyon-side wind and light rain.
Bring swimwear for the Secret Lagoon
Pack a swimsuit and quick-dry towel; the pool is naturally heated to 38–40°C and a great way to end a long day outdoors.
Secure your camera gear
Gullfoss and Strokkur are wet and windy—use a rain cover and a wide-angle lens for landscape shots.
Respect geothermal features
Stay on paths and follow guide instructions—ground can be unstable and hot springs are fragile ecological features.
Local Insights
Wildlife
- Arctic fox (rare, usually seen in remote areas)
- Various waterfowl including plovers and duck species near lake Þingvallavatn
History
Þingvellir is the site of Iceland’s Alþingi, established in 930 AD—the earliest parliamentary assembly in Europe—and the landscape still bears the marks of centuries of lawmaking and travel.
Conservation
Visitor pressure is managed by marked paths, signage and local rules; sticking to trails and following guide instructions helps protect fragile mosses, geothermal crust and breeding bird habitat.
