Thrihnukagigur Volcano Guided Hiking Day Trip

Reykjavik

Inside the Volcano Iceland: What to Arrange Before You Go

A short season, a meeting point that is not in Reykjavik, a walk that decides who can come, and a day it takes whole.

This is not a thing you slot into an afternoon. It runs in a short season, it starts at a ski hut half an hour outside the capital rather than in it, it asks for ninety minutes of walking on ground that punishes the wrong shoes, and it takes a whole day from a country most visitors see in four.

The four things that catch people out

Most of what goes wrong with this day is decided before anyone leaves their accommodation, and it is always one of the same four things.

The meeting point is not in Reykjavik. The start is a hut in the hills, some thirty minutes out of town, and anyone expecting to be collected downtown finds out at a bad moment. Transport there is an option you tick at booking rather than something that happens automatically.

The footwear requirement is literal. Hiking boots, and the operator specifically names trainers and jeans as not suitable, which is a level of directness you rarely see on a booking page and exists because the ground genuinely demands it.

The day is a whole day. Six hours plus the driving at either end leaves nothing usable afterwards, and anybody planning a second excursion for the same afternoon is going to be disappointed.

And the weather on the plateau is not the weather in the city. Half an hour and several hundred metres is enough to produce fog when the capital is in sunshine, which affects what you pack rather than whether you go.

The season, and why it is short

This runs in the warmer part of the year and stops for the rest of it. The constraint is not the chamber, which is the same temperature in February as in July, but the walk to it.

Getting a group of twenty across three kilometres of uneven lava field, and back, in weather that arrives without much notice, is a reasonable proposition for part of the year and not for the rest. When the operation stops, that is why.

Within the season the practical differences are daylight and the odds on the weather. This is a country where midsummer barely gets dark and midwinter barely gets light, and while the tour does not run in the depths of the latter, the shoulders of the season have noticeably shorter days and worse odds on a clear plateau.

Who the day suits

The filter is the walk, not the descent. Physically, being lowered on a platform and standing on a slope for an hour asks almost nothing of anybody. Ninety minutes over broken lava under moss asks a fair amount.

Anyone whose mobility is limited is told plainly by the operator that this trip will not work for them, and that is a description of the terrain rather than a form of words. There is no vehicle access to the crater and no shortened route.

For everyone else it is a question of ordinary fitness and sensible expectations. It is not steep and it is not fast, and it is uneven at every step, which is tiring in a way that distance alone does not convey. People who walk regularly find it unremarkable. People who do not find it the hardest part of the day.

Where the operator has not published a rule - a minimum age, for instance - this site will not invent one. Ask at booking; the answer is specific to the day and the group.

What the booking actually covers

The pattern here runs opposite to most people's expectations, so it is worth stating plainly.

Included: the descent, all safety gear, guides throughout, and a hot meal at the end - the lamb and root-vegetable broth Icelanders eat everywhere, a meat-free version for anyone who wants it, and a hot drink with something sweet alongside.

Optional: getting to the meeting point. Pickup and drop-off in Reykjavik is a choice made at booking rather than a default, and if you do not select it you are driving yourself to a cabin in the hills.

So the food is free and the transport may not be, which is the reverse of nearly every other excursion sold in this country. It is the single most common source of confusion about this booking.

Where it goes in an Iceland week

Give it a day and put that day early. The reasoning is entirely about weather: this is an outdoor operation on an exposed plateau with free cancellation, and a booking early in your stay can be moved if conditions are poor, while one on your last day cannot.

Do not pair it with the Golden Circle or the south coast. Those are long driving days in their own right and this is not an add-on to anything.

Do not put it on an arrival or departure day. The timings are fixed, the walk is real, and neither combines well with an airport.

And base yourself in Reykjavik, which is where almost everybody stays anyway and is the only sensible starting point given where the meeting cabin is.

Booking it

The throughput is five people at a time on a platform. That is a hard ceiling, and combined with a short season it makes this one of the few things in Iceland where booking ahead genuinely matters rather than being cautious advice.

Free cancellation is offered, which is the right arrangement for something the sky gets a vote on, and it is worth understanding as a scheduling tool rather than an insurance policy: it lets you hold a date early in your trip and move it if the plateau is having a bad week.

Arrive ten minutes before the stated time. Gear is fitted as a group, and a late arrival delays a schedule that ends in a winch running to a timetable.

Questions

Before you book

Where is the meeting point?
Breidabliksskali, a hut belonging to the Blafjoll ski area, roughly half an hour out of the capital on tarmac. Not a city address.
Is transport included?
Pickup and drop-off in Reykjavik is an option you select at booking rather than a default. Food is included; transport may not be.
What do I have to wear?
Hiking boots and warm layers. The operator names sneakers and jeans as unsuitable, and means it.
How long does the whole thing take?
Six hours, of which about ninety minutes is walking. Treat it as a full day.
Who is it not suitable for?
The operator rules it out for anyone with limited mobility. Nothing drives to the crater and there is no shorter way round.
When does it run?
In the warmer part of the year. The constraint is moving a group across a lava plateau safely, not the chamber itself.
How far ahead should I book?
Well ahead. Five people descend at a time, which caps how many can go per day, and the season is short.
What if the weather is bad?
Free cancellation is offered. Book early in your trip so a poor day can be moved.
Can I do it with children?
The walk decides it. A child who will happily do ninety minutes on rough ground will manage the rest easily.
Can I combine it with the Golden Circle?
No. Both are full days and this one leaves nothing usable afterwards.
