Iceland Diamond Circle Deep Dive: Complete 2025 Guide to Northern Fjords & Aurora Secrets
If the south’s Golden Circle is Iceland’s introductory-level attraction, the north’s Diamond Circle is the advanced traveller’s ultimate destination. This loop concentrates Iceland’s most spectacular waterfalls, strangest geothermal landscapes, and most mysterious fjords — with far fewer tourists than the south. This is genuinely uncharted territory.

The Diamond Circle is a classic self-drive loop in northern Iceland, approximately 260 km in total, connecting multiple iconic natural landmarks. Compared to the south’s Golden Circle, the Diamond Circle is rawer, less crowded, and allows you to experience Iceland’s true wilderness beauty.
Main waypoints: Húsavík → Lake Mývatn → Akureyri → Dettifoss → Húsavík
Húsavík — Iceland’s Whale Capital
Húsavík is one of Iceland’s oldest fishing villages and the best location for whale watching. Over 20 species of whale inhabit these waters, with a 98% whale-watching success rate.
Recommended activities:
- Whale-watching tour: 2–3 hour sea excursion with expert guide narration
- Húsavík Museum: Iceland’s fishing history
- Húsavík Church: charming white wooden church
Booking tip: Book whale-watching tours through Klook in advance — approximately $80–130/person including cold-weather gear.
Lake Mývatn — Geothermal Wonderland
Lake Mývatn is one of northern Iceland’s most important nature reserves, surrounded by extraordinary geothermal landscapes:
| Attraction | Feature | Visit Time |
|---|---|---|
| Námaskarð / Námafjall | Bubbling mud pools | 30 min |
| Dimmuborgir (Dark Castles) | Bizarre volcanic rock formations | 1 hour |
| Hverir | Sulphur deposits and geothermal fields | 30 min |
| Mývatn Nature Baths | Natural geothermal hot spring | 2–3 hours |
Mývatn Nature Baths is the ideal place to relax. Far fewer visitors than the Blue Lagoon, with more affordable pricing — book tickets in advance.
Akureyri — Iceland’s Northern Capital
Akureyri is Iceland’s second-largest city and the administrative centre of the north. Compact but with a distinctive cultural atmosphere:
Must-visit highlights:
- Akureyri Botanical Garden: rare plants near the Arctic Circle
- Akureyrarkirkja Church: city landmark
- Akureyri Swimming Pool: naturally geothermal-heated pool
- Christmas House: charming little shop selling seasonal treats year-round
Restaurant recommendation: Rub23 is a Michelin-recommended restaurant specialising in the fusion of Icelandic tradition and modern cuisine — approximately $50–80/person.
Dettifoss — Europe’s Most Powerful
Dettifoss is Europe’s most voluminous waterfall — approximately 100 metres wide, 45 metres high, with a thunderous, breathtaking flow. Located beside Route 1 (the Ring Road), approximately 2 hours’ drive from Akureyri.
Visiting tips:
- Dettifoss has east-bank and west-bank viewing platforms
- East bank is closer to the falls but requires walking a gravel path
- West bank has a car park and toilet facilities
- Bring a waterproof jacket and non-slip footwear
Goðafoss — The Mythically Beautiful Waterfall
Goðafoss (Waterfall of the Gods) is one of Iceland’s most beautiful waterfalls — horseshoe-shaped, approximately 30 metres wide. Legend holds that in the year 1000, when the Icelandic parliament declared Christianity the state religion, the lawspeaker threw his pagan idols into the falls — hence the name.
More accessible than Dettifoss and more aesthetically beautiful, this is a must-visit for photography enthusiasts.
Aurora Observation in the North
Northern Iceland is an exceptional aurora location. Compared to popular areas like Reykjavik, light pollution in the north is lower and aurora observation conditions are superior.
Best observation window: September through March on clear nights Aurora index: Use apps like My Aurora Forecast for real-time KP index updates Observation tip: Download offline maps — aurora observation spots are often in remote areas far from city lights
Self-Drive Notes
- Road conditions: Route 1 in the northern section has some gravel — a 4WD SUV is recommended
- Weather: Northern weather is highly changeable — check vedur.is forecasts before departing
- Fuel: Petrol station gaps are large — refuel whenever you drop below half a tank
- Connectivity: Buy an Iceland eSIM before departure to ensure navigation and communication
