Reykjavik Golden Circle Safety: Hot Springs, Cliffs, Cold Water and Winter Roads

The Golden Circle is a safe day out, and the risks it does have are specific. Know them before you go and you can relax at every stop. This page takes them in loop order, then gives you the numbers to save. If you are weighing Reykjavik Golden Circle guided tours against driving yourself, the last two sections matter most.

Þingvellir: crowds on a narrow path

The walk down the gorge is easy, but it is shared. When several coaches arrive at once, the path fills and people stop to take photos in the middle of it. Keep to the side, watch for ice on the steps in winter, and agree a meeting time with your group before you set off. If you drive, never stop on the road to take a picture: pull into a car park.

Geysir: boiling water behind a rope

The springs at Geysir are boiling, and the ground around them is thin crust in places. The Environment Agency requires you to stay on the marked paths. It also forbids throwing anything into the springs and bathing in them or their runoff. When Strokkur erupts, the wind carries the spray, and it can be hot close to the pool.

What to do: stand upwind, keep children in hand, and never step over a rope to get closer.

Gullfoss: spray, wind and wet steps

The paths at Gullfoss run close to the falls, and the spray soaks the path and the people on it. On a windy day it can feel like rain. In winter that spray freezes, and the steps and the path become slippery.

What to do: wear a waterproof layer and shoes with grip, and treat a roped-off path as closed, however good the view past it looks.

Kerið: a loose rim and a steep slope

Kerið's rim path runs over loose gravel, and the path down to the lake is steep. The entrance fee covers the paths around and into the crater, and those are where you should walk. Keep off the slopes between them.

What to do: take the marked path down, go slowly on the loose gravel, and watch children near the edge.

Silfra: cold water and a medical form

Silfra is 2 to 4 °C all year. The park says you must never enter it alone and must be in full mental and physical health. The combination day adds its own checks: a medical form, a doctor's clearance for some conditions, no glasses under the mask, and no snorkelling if you are pregnant. The guide and a drysuit are part of the fare.

Glacier snowmobiles on Langjökull

On the snowmobile day, two people share a machine, and one driver with a valid licence is needed for every two booked. Children aged 5 and under cannot ride. The ride can be cancelled after departure if the weather turns; ask the operator then for another date or a refund.

Winter roads

If you drive, the road is where the real risk is. Safetravel's rules for Iceland:

• Headlights on at all times, all year.
• No stopping on or beside the road for photos.
• Check the weather and the road conditions every morning, and again during the day.
• "Lokað" on a sign means the road is closed.
• Driving off the road is forbidden everywhere.
• Single-lane bridges: the car that reaches the bridge first goes first.

Short winter daylight adds to it. In December you get about 4 hours of daylight, so a full loop means driving back in the dark.

Numbers to have

Save them before you leave Reykjavík. You do not want to be searching for a number in the cold.

What a tour takes off your hands

A tour removes the part of the day most likely to go wrong: driving an unfamiliar road in the dark, in wind or on ice. The driver knows where the car parks are and when to turn back. The guide knows which path is icy that week. And if the weather closes a road or cancels the snowmobile, you get another date or your money back. Every tour here also refunds in full if you cancel at least 24 hours ahead.

Asked about safety

Where these rules come from

The rules at Geysir and Gullfoss are the Environment Agency's, the Silfra rules are the national park's, and the driving rules and the numbers are Safetravel's and the Road and Coastal Administration's, read 23 September 2026. The snowmobile and snorkel conditions are each tour's own listing.

• The Geysir area: protection and visitor rules (Environment Agency, in Icelandic)
• Gullfoss: protection and visitor rules (Environment Agency, in Icelandic)
• Diving and snorkelling in Silfra: the rules (national park)
• Kerið crater: entrance fee and what it covers (the landowners)
• Safe travel in Iceland: driving, alerts and the 112 app
