Driving tips

What to watch for, how to drive, and the signs on this trip.

Watch out

• Warning

  Reynisfjara warning lights

  Yellow/red system — never green. After 2025 fatalities and a February 2026 landslide, the red threshold was lowered and a gate now blocks the cave and columns. Stay ≥30 m from the water. Never turn your back to the sea. Treat it as a brief, stay-back viewpoint.

• Warning

  Night driving on two days

  Sep 27 and Sep 29 are the failure days. Sunset ~19:03–19:17; full dark by ~20:00. Headlights always on. Slow for sheep. Use only designated pull-offs for aurora — never stop on the carriageway.

• Warning

  Reykjanes eruption watch

  No eruption as of August 2026 (last Sundhnúkur event Jul 16–Aug 5, 2025). IMO reports more magma under Svartsengi than at any point in the series; another eruption is considered likely in weeks or months. KEF and Route 1 have been unaffected. Blue Lagoon can close at short notice.

How to drive

• Chip-and-PIN before you leave town

  Many unmanned Orkan/ÓB pumps need a chip-and-PIN card. Orkan also takes Apple/Google Pay. Verify the PIN at a staffed N1 (Hella 24h, Vík, Kirkjubæjarklaustur 09:00–22:00) and top up during open hours.

• Parking apps

  Parka for most south-coast lots (Sólheimajökull, Fjaðrárgljúfur, Dyrhólaey). EasyPark for Kirkjufell (24/7). Download both before you lose signal.

• Aurora window

  Late September is an excellent equinox window (Russell–McPherron). In Iceland, Kp 2–3 is enough with clear skies. Best 21:00–02:00. Use vedur.is aurora + cloud map and the NOAA SWPC 3-day Kp forecast.

• Pace threshold

  If combined pace (stops + driving) runs below ~40 km/h, drop Djúpalónssandur on Sep 27 and Fjaðrárgljúfur on Sep 29.

• Mobility discipline

  Reynisfjara: stay behind the warning-light line. Kerið, Fjaðrárgljúfur, Gullfoss: flat rim / upper viewpoint only — skip stairs and descents. Djúpalónssandur: viewpoints, not the beach. Seljalandsfoss: skip the behind-falls loop.

Road signs

• Headlights always on

  Required all year. The Auto setting is not enough. Days 2 and 4 finish after dark — lights before you roll.

• No stopping

  Stopping or parking is prohibited. Aurora, sheep, and waterfalls are not a reason. Use a designated lot. Never the carriageway.

• Sheep on the road

  Possibility of sheep on the road. Drive carefully — they may jump in with short notice. Night returns on Days 2 and 4 are the failure.

• Paved road changes to gravel

  Tyres lose grip at the join. Slow before you leave the tarmac, then keep it slow. Flying stones chip glass if you rush.

• Single-lane bridge

  Common on the south coast. Slow down — another car may be coming. The car that arrives first crosses first. If in doubt, give way.

• Closed road — Lokað

  Closed for all vehicles, including bikes. Pedestrians may walk; you may push a bike. Closed means closed. Never improvise a highland shortcut.

• Blind crest

  Keep to the far right and slow down. Oncoming traffic can be hidden over the rise.

• Roundabout

  Two-lane: first exit = outer (right) lane; further exits = inner (left). No lane changes once inside. The inner lane has right of way when exiting. Signal out.

• Unbridged rivers

  Mostly on F-roads, 4×4 only. This itinerary stays on paved Route 1 / 54 / Golden Circle. If you see an unbridged river, you took a wrong turn.
