The Icelandic Meteorological Office (IMO) has issued a heightened alert for the Svartsengi volcanic system on the Reykjanes Peninsula, warning that an eruption at the Sundhnúkur crater row is “the most likely scenario in coming weeks.” Ground deformation measurements confirm that approximately 26 million cubic metres of magma have accumulated beneath the system since the last eruption in the series ended in August 2025 — a volume the IMO describes as higher than at any point during the 2023–2025 eruption cycle.

No eruption is currently underway. However, the pattern of build-up and release that has characterised the Reykjanes Peninsula since 2021 makes this the most monitored geological zone in Europe right now, and travellers planning to visit should understand both the risk level and the practical implications.

Is Iceland Safe to Visit?

Yes. The eruption series on the Reykjanes Peninsula since 2021 has consisted entirely of effusive fissure eruptions — fast-moving lava flows rather than explosive events. These do not produce significant ash clouds of the kind that grounded European air traffic in 2010. Keflavík International Airport, despite being on the peninsula, has not been disrupted by any eruption in this series and is not considered at risk in current IMO modelling.

What has been affected are specific local roads and hiking trails within the active zone. The Blue Lagoon geothermal spa, which sits on the Reykjanes Peninsula, has closed temporarily during active eruptions in the past and may do so again — check current status before booking.

What to Expect on the Ground

If an eruption begins while you are in Iceland, safetravel.is is the authoritative source for road closures and exclusion zones. Authorities respond quickly, and the closures are typically well-defined. Travellers who stay outside marked restricted areas are not in danger. Volcano tours — helicopter flights and Super Jeep experiences over recent lava fields — have operated successfully throughout the entire eruption series and remain a legitimate attraction.

Reykjavik itself, 45 kilometres from the active zone, is entirely unaffected. For a broader understanding of risks and practical travel conditions on the peninsula, see our Iceland safety guide.

Flights and Insurance

Airlines continue operating normally. For peace of mind, travel insurance that explicitly covers natural event disruptions is worth considering; check whether your policy includes volcanic activity as a covered cause of cancellation or curtailment before departing.

The IMO updates its eruption status daily at vedur.is. We recommend bookmarking this and checking the morning of any planned Reykjanes Peninsula activities.

Blue Lagoon: Current Status

The Blue Lagoon geothermal spa (Blaalonid) sits approximately 3.5 km from the Svartsengi volcanic system on the Reykjanes Peninsula — close enough that it has closed temporarily during active eruptions in the 2023-2025 series. As of June 2026, the Blue Lagoon is operating normally. Its management monitors IMO data continuously and communicates directly with guests if conditions require evacuation or temporary closure.

Blue Lagoon bookings are non-refundable under standard terms but the property has issued refunds during genuine volcanic closures — check current refund policy at the time of booking rather than relying on historical practice. If you are booking more than two weeks out with IMO alerts elevated, consider the Blue Lagoon’s own cancellation terms and whether your travel insurance covers volcanic activity as a covered cause of trip disruption.

Current Blue Lagoon entry prices start from approximately ISK 12,500 for the Comfort package (access, silica mud mask, one drink, towel) rising to ISK 23,000+ for higher tiers. Booking at least 24-48 hours in advance is mandatory — same-day slots exist but are rare and expensive.

Volcano Tour Options

Iceland’s active volcanic situation is a tourism asset as much as a risk, and a range of tour operators run visits to recent lava fields and, when safe, to active eruption sites:

  • Super Jeep eruption tours: When an eruption is active and the exclusion zone allows approach, operators including Midgard Adventure, Troll Expeditions, and Arctic Adventures run small-group super-jeep access from Reykjavik (typically 4-6 hours, from approximately ISK 35,000-45,000 per person as of 2026).
  • Helicopter tours: Atlantsflug and other operators offer helicopter overflights of the Reykjanes lava fields regardless of eruption status. Flights are weather-dependent; from approximately ISK 55,000-75,000 per person for a 45-60 minute flight.
  • Guided walks on cooled lava fields: The 2021-2025 eruption sites at Fagradalsfjall and Litli-Hrutur are now accessible on foot with guides, offering close-up access to solidified lava tunnels and formations. Operators like Extreme Iceland and Reykjavik Excursions run these as day tours from the capital (ISK 12,000-18,000, including transport).

All prices are approximate and subject to change.

Practical Safety Framework

Iceland has developed one of the world’s most systematic approaches to managing volcanic tourism. The safetravel.is platform is the government’s central source for real-time exclusion zones, road closures, and safety guidance. During an active eruption:

  1. Exclusion zones are set by Almannavarnir (Civil Protection) and are enforced — do not attempt to enter them.
  2. Road.is shows which specific roads are closed; this is the authoritative source for the Sudurstrandarvegur and Reykjanesbraut roads that access the peninsula.
  3. Air traffic control maintains separation from eruption columns; flights to Keflavik are unaffected by effusive fissure eruptions of the type seen in the current series.
  4. If you are staying anywhere on the Reykjanes Peninsula and an eruption begins, follow Civil Protection guidance — evacuation of nearby towns (Grindavik in particular) has been practised multiple times since 2023.
