Northern lights remain visible in March, offering a pivotal period where one can sometimes enjoy both light phenomena in a few days. Trails gradually clear and prices remain attractive before the high season.

Temperatures: -7°C – 10°C / 19°F – 50°F

Events in Mývatn

Calendar of must-see highlights around Lake Mývatn

Mývatn focuses its highlights around seasonal natural phenomena — midnight sun, auroras, bird migration — which structure the visitor calendar and create moments of incomparable intensity.

🌅 Midnight Sun — June to mid-July

The midnight sun is arguably the most iconic phenomenon of the Icelandic summer. In Mývatn, the sun does not set between late May and mid-July, creating a golden, low-angle light at all hours that radically transforms the volcanic landscapes. Hikers set off towards Dimmuborgir at 11 PM under permanent late-afternoon light.

Location: Entire Mývatn territory, particularly Dimmuborgir, Krafla, and the lake shores.

Special feature: Natural phenomenon requiring no special organization, but justifying the trip on its own.

Weather impact: High season is in full swing; accommodations are fully booked weeks in advance.

Access: Route 848 from Reykjahlíð, fully drivable in summer.

Tip: Book accommodation and car rental at least 3 months in advance for June-July.

🦆 Bird Nesting Season — May to August

Lake Mývatn is one of the most important ornithological sites in Europe, hosting over 115 bird species, including a world-unique diversity of diving ducks. From May to August, ornithologists from around the world converge on its shores to observe nesting in exceptional conditions. A spectacle accessible to everyone, from beginners to specialists.

Location: Shores of Lake Mývatn, Neslandatangi, Höfði, Skútustaðagígar.

Special feature: Density of duck species unique in the world thanks to the volcanic lake's invertebrate-rich waters.

Weather impact: Activity is maximal in good weather, but birds remain active even in the rain.

Access: Trails around the lake are free and accessible without a vehicle from Reykjahlíð.

Tip: Bring binoculars and an ornithological guide; May-June offers the best observations of courtship displays.

🌌 Northern Lights Season — September to March

The northern lights are the great winter attraction of Mývatn. The absence of light pollution in this isolated region of Northern Iceland, combined with the high latitude, creates some of the best observation conditions in Europe. The green, red, and violet dancers of the sky regularly illuminate the nights between September and March, above the vapors of the fumaroles.

Location: Entire Mývatn territory, far from any artificial light source. The lake shores and the Hverir area are particularly appreciated by photographers.

Special feature: The combination of geothermal vapors in the foreground and auroras above is visually spectacular and unique in the world.

Weather impact: Clear, cloudless nights are essential; check the Vedur.is app for auroral activity forecasts.

Access: Moving 2 to 3 km (1.2 to 1.9 miles) away from Reykjahlíð is enough for near-total darkness.

Tip: Stay at least 3 to 4 nights to maximize the chances of observation under clear skies.

Traveling Responsibly in Mývatn

Mývatn is a fragile ecosystem classified as a nature reserve. Every visitor has the responsibility to minimize their impact on this unique volcanic territory whose natural balance is threatened by summer overcrowding.

Lake Mývatn and its surroundings have been protected by Icelandic law since 1974. Marked trails must be respected scrupulously: walking off-path destroys volcanic moss that takes decades to regrow. The lava formations of Dimmuborgir and the pseudo-craters are particularly vulnerable to trampling. Favor local accommodations over large chains, and respect the tranquility of the few permanent inhabitants of the area.

🌱 Low-season advantages

Traveling to Mývatn outside of July-August considerably reduces pressure on trails and natural sites, allows for a more authentic experience of Icelandic nature, supports local accommodations in the off-season, and generates fewer emissions related to group travel.

♻️ Sustainable travel tips

  • 🚶 Strictly respect marked trails: volcanic moss takes 100 years to recover once trampled.
  • 🚗 Carpool from Akureyri with other travelers to reduce carbon footprint.
  • 🏠 Choose local Icelandic guesthouses rather than international chain accommodations.
  • 🗑️ Take your trash with you: collection infrastructure is almost non-existent in the area.
  • 🔇 Respect natural silence and the tranquility of nesting birds, especially from May to July.
  • 💧 Do not use soap or cream in natural geothermal zones that are not developed.

🏙️ Local sustainable initiatives

Iceland is among the countries most committed to renewable energy (100% electricity from geothermal and hydroelectric sources). The Mývatn region is actively working on regulating the number of visitors to sensitive sites. Mývatn Nature Baths are managed with strict environmental commitments, and the lake's nature reserve is subject to reinforced protection regulations.

Frequently Asked Questions

Here are the answers to essential questions for planning your stay in Mývatn according to the season, budget, and your desire for Icelandic nature.

What is the best month to visit Mývatn?

The best month to visit Mývatn depends on what you are looking for. June is ideal to combine the midnight sun, exceptional birdwatching, and acceptable temperatures, with even fewer crowds than in July. July offers the mildest temperatures but corresponds to the peak of traffic and midges. September is the perfect month if you want to combine the first northern lights of the season, spectacular autumn landscapes, and regained tranquility. For auroras in complete serenity, October-November remains very attractive with attractive prices.

How many days should I plan to visit Mývatn?

Count on a minimum of 2 full days to see the essential sites: Dimmuborgir, Hverir, Skútustaðagígar, and the Mývatn Nature Baths. 3 to 4 days allow you to include Krafla and Leirhnjúkur, practice birdwatching serenely, and give yourself more chances to observe the northern lights outside the summer season. If you are chasing auroras, plan for 4 to 5 nights minimum to maximize the probabilities of having a clear sky. Mývatn fits ideally into a Ring Road tour of Iceland.

What to do in Mývatn in case of rain?

Rain does not spoil the Mývatn experience, quite the contrary! Start with the Mývatn Nature Baths — bathing in water at 38°C (100°F) under the Icelandic rain is an unforgettable experience. Then visit Hverir, where the fumaroles and mud pools are even more dramatic under a cloudy sky. The Neslandatangi bird observatory allows you to observe ducks under shelter. Finally, a visit to the village of Reykjahlíð and its small historic church pleasantly completes a wet day.

What events should not be missed in Mývatn?

In Mývatn, major events are primarily natural and seasonal. Do not miss the midnight sun in June-July for hikes under permanent golden light. The bird nesting season (May-July) with its 115 species is unique in Europe. The northern lights (September to March) are the highlight of the winter show. In January-February, the Þorrablót, a traditional Icelandic festival, is sometimes celebrated in local guesthouses with typical dishes and conviviality. The Icelandic National Day on June 17th leads to events in Akureyri, 1h15 away by car.

What budget should I plan according to the period in Mývatn?

Iceland is an expensive destination regardless of the season. In high season (June-July), count on €200 to €400/day for two people (accommodation + car + meals + attractions). In low season (November-March), the budget can drop to €120-250/day thanks to cheaper accommodations, but 4x4 rental remains essential and expensive (€40-70/day). The shoulder season (May, September) represents the best value for money with accommodations 30 to 40% cheaper than in July. Always plan a substantial provision budget because restaurants in Mývatn are rare and expensive.
