Thingvellir National Park closes bridges after 31 October floods

Thingvellir National Park closed bridges after flooding in the River Öxará on 31 October 2026, according to the park authority. The notice concerns the historic Icelandic landscape around Thingvellir, where the river passes the former site of the Althing assembly.

Flooding closes bridges at Thingvellir on 31 October

The park’s current news notice says that floods in the River Öxará led to the closure of bridges on 31 October 2026. It does not specify how many bridges are affected, how long the restriction will last or whether alternative crossings are available.

The information is an access update rather than a general weather forecast. Travellers planning a visit to the national park should therefore treat the affected bridge route as unavailable unless the operator posts a later change. The notice does not announce a closure of the entire park.

The operator has previously described flood damage to pedestrian bridges over the same river. A separate park notice says that a walkway between Lögberg and Flosagjá was closed after river damage and that the route required repair. That earlier notice is not used to establish the 31 October 2026 restriction, but it shows why water levels in the river matter for movement through the assembly area.

The park’s flood notice places the access change in the River Öxará area and names the closed bridges. The same page also lists other visitor updates, but none is used here as a second current peg.

The River Öxará runs through a World Heritage landscape

The river is part of the setting that gives the national park its historical identity. The park authority says the Althing general assembly was established at Thingvellir around 930 and continued to meet there until 1798. The site is now protected as a national shrine in Iceland.

UNESCO describes the property as including the remains of the Althing, with fragments of around 50 booths built from turf and stone. Remains from the tenth century are thought to survive underground, while the wider landscape also records agricultural use from the eighteenth and nineteenth centuries.

This makes the 31 October bridge closure relevant beyond a single piece of park infrastructure. A crossing over the Öxará can form part of access to a landscape where political and social history is visible through archaeological remains, paths and the river valley. The restriction may therefore change how visitors reach parts of the historic area without changing the status of the wider World Heritage setting.

UNESCO’s Thingvellir record identifies the park in Iceland and dates the Althing’s use of the site from 930 to 1798. It also records the property’s publication in 2004.

Why the Öxará crossing matters to the visit

Thingvellir lies in Iceland’s rift landscape, where faults and fissures reveal the movement of the earth’s crust. The park authority describes the area as part of the Mid-Atlantic Ridge and links its geology with Lake Thingvallavatn and the surrounding gorges.

The current notice gives no information about water levels, safety conditions away from the bridges or the reopening date. Visitors should not infer that a closed bridge can be crossed on foot, and should follow any signs or instructions issued at the site.
