Reynisfjara black sand beach

6 min read Updated October 2026 Compare all tours

Reynisfjara lies below Reynisfjall, the mountain that rises above the village of Vík. Visit South Iceland describes Reynisfjall as a 340 m tuff mountain formed by an eruption under the ice during the second-to-last glacial period, with layers of columnar basalt, tuff and pillow lava. Out in the sea stand the Reynisdrangar, a group of rock pillars 66 m high that formed in the same way as the mountain.

The beach itself is black sand and pebbles facing the open sea. The water, not the rock, is the reason for the signs and the warning light at its access. Parking has been charged since July 2023 and is paid through the Parka system.

The basalt columns and the cave

Where the mountain meets the beach, the rock shows walls of six-sided basalt columns standing on the sand. Beside them is the cave Hálsanefshellir, which the regional tourist board calls exceedingly beautiful. Both are right at the water's edge, and this is the spot where the risk concentrates: according to a spokesperson for the landowners, the last three fatal accidents on the beach all happened by the basalt columns.

Why the waves are dangerous

Visit South Iceland warns that the waves here are deceptive and have caused the death of a number of visitors in recent years, even in the best of weather. In English they are often called sneaker waves: a single wave runs much further up the sand than the ones before it, without warning.

The landowners count six fatal accidents at Reynisfjara this century, four of them drownings; two were not related to the waves. The first fatal accident involving a tourist was in 2007, and the most recent in August 2025, when the light showed yellow.

How the warning lights work

In December 2022 a consultation group of landowners, the police, the Icelandic Tourist Board, the rescue association ICE-SAR, the Road and Coastal Administration and Katla Geopark completed a new system. It consists of a light signal, three large information boards, six direction signs and a 300 m chain that leads visitors from the car park past the signs. Police cameras on a mast send live images to the police station in Selfoss. The light is linked to an automatic wave forecast run by the Road and Coastal Administration.

According to the landowners, the light shows green when the danger is low, yellow for moderate danger and red for high risk. The beach is never closed as a whole. It is divided into zones by level of danger instead. When the light is yellow you must not enter the yellow zone, and when it is red you must not enter the red zone or go past the light sign. From the beach crest, the raised bank behind the sand, you can watch the waves safely in any conditions. There is no safety staff on site.

After the accident in 2025 the rules were tightened. The danger index was recalibrated using sea level, beach width and the way waves hit the basalt columns, so the red light comes on earlier than before. With a red light, access from the viewing platform on the beach crest is shut, and walking to the basalt columns or into Hálsanefshellir is forbidden. A closure gate for red-light days was due to be installed within days, and in September 2025 a barrier stood across the path while the light was red. The landowners, the Tourist Board, the South Iceland Police, Safetravel and the local rescue team Víkverji also set up a safety group that meets regularly.

The erosion of February 2026

In February 2026 heavy seas eroded the beach. At high tide on Sunday 22 February the ground beneath the viewing platform and two of the safety signs washed away. The sign with the zone map collapsed, and the illuminated warning sign was removed because its foundations had been undermined. The Icelandic Tourist Board then reported that visitors could go only as far as the upper beach ridge, with no way down to the basalt columns, while the car park, the restaurant and the toilets stayed open. The landowners announced new safety signs and a rebuilt viewing platform. We found no later official notice about the new signs, so check what is in place when you arrive and follow it.

Kirkjufjara and the view west

West of Reynisfjara the coast continues towards the Dyrhólaey headland. The smaller beach below it, Kirkjufjara, has been closed to visitors after rock falls and accidents at sea between 2012 and 2017, according to the Environment Agency. The headland above is open, with seasonal limits in the nesting season, and is described on our Dyrhólaey page.

Seeing the beach from above or on horseback

A guided walk from Vík climbs Reynisfjall and follows its top for about 40 minutes to the south-facing cliff, where the Reynisdrangar and the black beach lie directly below. In summer puffins nest along these cliffs. The walk starts behind the information centre in the village, takes children from 6 and groups of up to 17. It is a new listing, so check the details when you book.

Tandem paragliders usually take off from the same mountain and spend 10 to 15 minutes in the air over the coast. On horseback, a three-hour ride crosses rivers and fields to the coastline near Reynisfjara, with about an hour at a viewpoint; riders must be at least 10 and no heavier than 100 kg.

More rides are on our horse riding page, and the flights are compared under kayaking, paragliding and zipline.

Light and weather through the year

You can visit the beach in any month. In midwinter the sun is up for about four and a half hours, from 10:59 to 15:29 on 21 December. In June the sun sets after 23:30 and the night stays bright. Whatever the season, the signs and the light at the access decide how far you may walk. Before you drive, the Safetravel app lets you leave a travel plan and send your position to 112 in an emergency.
