Daylight through the year

Iceland's daylight swings further than almost anywhere people holiday, and it decides what a tour can actually show you. Times are for the 15th of each month at this spot.

What is seasonal here

None of these have fixed dates, so each one says what its real dates depend on.

Midnight sun

May–July

True midnight sun only above the Arctic Circle — Grímsey. The mainland gets civil twilight all night, which looks much the same.

Lupine in bloom

June–July

Introduced, controversial and impossible to miss when it flowers. Peaks a fortnight later in the north than the south.

What people do here

Getting here without a car

The 8 tours we sell that stop at Raufarhólshellir (the Lava Tunnel) leave from Reykjavík and Selfoss. Most of them start in Reykjavík, so for anyone based in the capital there is nothing to arrange beforehand.

7 of the 8 collect you from your accommodation or a designated stop, so the tour is the transport — there is nothing else to arrange and no timetable to read.

A seat on a day tour here starts at €165 and typically runs €191, per person, private charters excluded because those are priced per vehicle and would flatter the figure. There is no scheduled bus we can sell you to Raufarhólshellir (the Lava Tunnel), so a guided day is the practical way in without a car.

The days themselves run from about 3 h to 10 h door to door, so check the length as carefully as the price — the cheapest seat is often the longest coach day. 4 different operators run here, which matters more without a car than with one: if the weather cancels your day, there is usually another departure rather than a lost trip.

Being driven is the easy answer here: enough operators run it that a cancellation rarely loses you the day, and you get to look out of the window instead of at the road.

Cheapest way in without a car: a guided day tour from Reykjavík, from €165 per person.

We have done the sums on this properly: what a rental car actually costs against guided tours.

Raufarhólshellir (the Lava Tunnel): questions people ask

How many tours go to Raufarhólshellir (the Lava Tunnel)?

We list 9 — 8 day tours and 1 multi-day packages, from 5 operators. That is what we currently have contracts for, not everything that exists in Iceland.

How much does it cost to visit Raufarhólshellir (the Lava Tunnel)?

The place itself is usually free to enter; what you pay for is getting there. A day tour seat runs from €165, with a typical price of €216. Some sites charge separately for parking or admission — check the individual tour.

When can you visit Raufarhólshellir (the Lava Tunnel)?

Looking at the next 360 days of live availability, departures fall in October, November, December, January, February, March, April, May, June, July, August, September. That is a rolling window rather than the full year, so a month missing here is not necessarily a month with nothing running.

How much daylight is there at Raufarhólshellir (the Lava Tunnel)?

January: 5 h 23 min · March: 11 h 34 min · June: 20 h 50 min · September: 13 h 11 min · December: 4 h 22 min. Iceland stays on UTC all year, so there is no clock change to allow for.

Do you need a tour, or can you drive to Raufarhólshellir (the Lava Tunnel) yourself?

Both work. Driving gives you the stops you want and the time you want them; a tour removes the winter road decisions and lets everyone look out of the window. We sell the tours and say so — if self-driving suits you better, it suits you better.

Can you get to Raufarhólshellir (the Lava Tunnel) without a car?

Yes — 8 guided day tours in our catalogue stop here. 7 of the tours pick you up from your accommodation, so no onward transport is needed.

What is the cheapest way to get to Raufarhólshellir (the Lava Tunnel)?

A guided day tour from Reykjavík, from €165 per person, with €191 the more typical fare. Private tours cost more because they are priced per vehicle rather than per seat.
