Mývatn
A milk-blue volcanic lake surrounded by pseudo-craters, lava castles, fumaroles, and a geothermal spa that locals quietly prefer to the Blue Lagoon. The geological centrepiece of north Iceland.
Why this place matters.
Mývatn formed in a basaltic flood eruption 2,300 years ago. The lake is shallow and rich in geology — pseudo-craters at Skútustaðir, lava pillars at Dimmuborgir, the steaming mud-pot field of Hverir, and the high-saturation thermal valley of Námafjall.
The canonical loop is Route 1 north of the lake plus Route 848 south — a 35 km circuit with stops at Skútustaðir pseudo-craters, Dimmuborgir lava castles, Grjótagjá lava cave (private land — look, no bathing), the Mývatn Nature Baths, and the Hverir mud pots east on Route 1. Add Krafla caldera + Leirhnjukur lava field for a fuller day.
North · Diamond Circle interior.
On Route 1 east of Akureyri, west of Egilsstaðir. Natural overnight stop.
Worth visiting — read the fine print.
Honest, not cynical. These are the things returning visitors tell first-timers.
Mývatn means 'midge lake'. They don't bite (the kind here) but they swarm. Head net useful in late June + early July dusk.
Intense — not for asthma or pregnancy. Stay on the marked paths. Boardwalks for safety, not for the smell.
Private land — the owners prohibit bathing. Looking and photographing is fine. The cave is open to view (Game of Thrones fans). Don't enter alone in winter.
Smaller, cheaper, fewer crowds, equally turquoise. Pre-book in summer; walk-up usually fine in shoulder.
Lava castles formed by gas-explosion. Boardwalks, easy walking, dramatic at sunrise. Almost empty before 9am.
20 min north on Route 863. Walk through still-warm lava (1980s eruption). Most underrated stop in the region.
When the place is itself.
Peak Jun – Sep. Winter remains possible with reduced access — Route 848 south of the lake sometimes closes in storms. Aurora over the lake is exceptional.
Light, shaped by ice.
Lava castles + low side-light. Best 6 – 9am summer. Empty before 9. Wide-angle for the dramatic scale.
Sulfur-yellow earth, steaming vents, blue mud pots. Wide angle low. Best midday — colour is fullest then.
Pseudo-craters around the lake edge. Compose with the lake and Hverfjall (volcanic crater) behind.
Winter. Calm nights give mirror reflections. Compose with a small island or shoreline foreground.
Getting there, calmly.
