Iceland Guide: Nature, Geysers, Northern Lights

Iceland isn’t a normal destination. Volcanoes that erupted last year, glaciers that might be gone in 30 years, and northern lights you don’t plan, you chase. The country is dramatic, expensive and unlike anywhere else. Here’s how to get the most out of your trip.

Two Ways to Experience Iceland

Option 1: Reykjavik plus South Coast (4 to 5 days) The classic. You land at Keflavik, sleep in Reykjavik, do the Golden Circle as a day trip and drive two days along the south coast taking in Seljalandsfoss, Skógafoss, Vík and the black beach Reynisfjara. Compact and intense.

Option 2: Full Ring Road (8 to 12 days) Route 1, 1,332 kilometers around the island. You see everything: south coast, east fjords, north Iceland with Akureyri, the Golden Circle. This is the experience that really shows you Iceland.

For both you need a rental car. Without a car, you won’t really experience Iceland.

What is the Golden Circle and what must you see?

Three stops within 250 kilometers, doable in a single day.

Þingvellir National Park: the tectonic plates of Europe and North America drift apart here. You walk through the rift. UNESCO World Heritage, old Viking parliament.

Geysir / Strokkur: the Geysir that named all big geysers in the world. Strokkur shoots 20 to 30 meters of water into the air every 5 to 10 minutes.

Gullfoss: a two-tier waterfall, 32 meters deep. Partly frozen in winter. The name means “Golden Waterfall”.

Blue Lagoon or Sky Lagoon: Which is better?

Both are geothermal spa landscapes, both expensive (70 to 100 euros), both worth it, but differently.

Blue Lagoon: the iconic picture. 30 minutes from the airport. High visitor volume, slots must be booked weeks ahead. The experience is touristy but spectacular.

Sky Lagoon: newer (2021), closer to Reykjavik, more modern. 7-step ritual with sauna and cold plunge at the ocean. Less crowded. Insider tip: better for a calmer experience.

My tip: plan the Blue Lagoon on your departure day before your flight. You’re near the airport anyway, and after the trip it’s relaxing.

Northern Lights: when and where

September to March is the season. January and February are statistically best. You need:

Clear sky (clouds are the biggest enemy)
Strong solar activity (Kp index 4 or higher)
Distance from light pollution

The aurora forecast at the Icelandic Meteorology Agency is essential. Plan 3 to 5 nights at accommodation outside Reykjavik (e.g. Hotel Rangá in the south) so you get multiple chances.

Glaciers: the urgent trip

Iceland’s glaciers lose ice every year. In 50 years they could be gone. Those who go now still see them.

Sólheimajökull: easy to reach, 2 hours from Reykjavik. Guided glacier tours from 90 euros.

Jökulsárlón Glacier Lagoon: icebergs float in a lagoon, some drift to the black Diamond Beach. 4.5 hours from Reykjavik, a full day needed.

Vatnajökull Glacier: Europe’s largest. In winter you can go inside ice caves that form anew every year. Guided tours only, from 180 euros.

Volcanoes and Geothermal

Iceland is the only place in the world where the Mid-Atlantic Ridge sits above water. That’s why so many volcanoes and hot springs.

Landmannalaugar: colorful rhyolite mountains and natural hot springs in the wild. Only accessible in summer (June to September). 4x4 or organized tour required.

Reykjanes Peninsula: Fagradalsfjall last erupted in 2023 here. Guided lava-field hikes are possible when safe.

Lake Mývatn in the north: geothermal fields, pseudo-craters, and the Mývatn Nature Baths (cheaper alternative to Blue Lagoon).

Rental Car: your Iceland tool

A rental car in Iceland is more expensive than almost anywhere else. 80 to 150 euros per day for a regular SUV. In summer for the F-roads (highlands) absolutely a 4x4 with high ground clearance.

Insurance: Iceland has special insurances you only get there. Gravel Protection, sand and ash storm protection are important because those damages happen often. A rental consolidator helps bundle all these insurances up front.

Hidden costs: gasoline is expensive (about 2.20 euros per liter). Plan 150 to 250 euros for fuel on the Ring Road. More on hidden rental car costs in our dedicated article.

How expensive is Iceland really?

Iceland is one of the most expensive travel destinations in the world. Realistic costs per person for a week:

Flights from Europe: 300 to 600 euros
Rental car (7 days, split by 2): 350 euros
Midrange accommodation: 700 to 1,000 euros
Food: 40 to 60 euros per day
Activities: 300 to 500 euros
Total: 1,800 to 2,800 euros per person

Savings tips: Bónus supermarket instead of restaurants. Hot dogs (pylsur) are the Icelandic fast food classic at 5 euros. Airbnb or guesthouses instead of hotels.

When is the best time to visit Iceland?

June to August: midnight sun, best roads, most expensive. Highlands accessible.
September to October: northern lights start, fewer tourists, good prices. My favorite.
November to March: winter adventure, ice caves, northern lights. Short days, dangerous roads. Experienced drivers.
April to May: shoulder season, roads reopen, moderate prices.

Zercy helps you find flights to Keflavik, the right rental car with proper insurance and accommodations along the Ring Road. The Zercy Logbook organizes all bookings as a timeline, so your 8-day Ring Road trip stays manageable.

Frequently Asked Questions

When do you see northern lights at their best?

Late September through March, peaking in January and February. You need clear sky and strong solar activity (Kp index 4 or higher). Plan at least 3 nights outside Reykjavik so you get multiple chances. The aurora forecast at vedur.is is your most important tool.

How much time do you need for the Ring Road?

Minimum 7 days, realistically 10. Under 7 days you rush through and miss the side roads that are often the most beautiful (Snæfellsnes Peninsula, Westfjords). With 10 to 12 days you can dig into fjords, hot springs off the main route and hiking.

Why is Iceland so expensive?

Iceland imports almost everything. The country has 380,000 inhabitants, a strong currency and little tourism competition. A normal lunch runs 25 to 35 euros, a tank of fuel 90 to 120 euros, a hotel standard room 200 to 300 euros. Budget realistically before the trip.

Which insurance do you need for the rental car?

At minimum Gravel Protection and sand and ash storm insurance. Standard full coverage often doesn’t include those. The extra policies cost 15 to 25 euros per day, but they pay off because stone chip damage on the gravel side roads is common.
