When to go
Any season
Winter brings stormy skies; summer is better for coastal walks. Watch wind forecasts either way.
Region
Reykjanes Peninsula Travel Guide
Lava coastlines, geothermal heat, and big Atlantic weather. Raw Iceland within an hour of the airport.
Good for
Half-day loop
Lots of scenery with minimal driving. Good at the start or end of a trip.
The Reykjanes Peninsula sits directly on the Mid-Atlantic Ridge, where the North American and Eurasian tectonic plates pull apart. Its steaming vents, mud pots, and fresh lava fields made global headlines when a series of eruptions beginning in 2021 at Fagradalsfjall ended roughly 800 years of volcanic dormancy. For most visitors this is the first and last landscape they see in Iceland, and there is more to it than the airport road.

Geothermal stops and coastal viewpoints along a short loop.
Gunnuhver
Iceland's largest mud pool and one of its most active geothermal areas, located near the southwestern tip of the Reykjanes Peninsula about 50 km from Reykjavik. Boardwalk paths lead past boiling mud pots, hissing steam vents, and ground temperatures exceeding 300 degrees Celsius below the surface. Stay strictly on marked paths and behind barriers, as the thin crust can collapse. The visit takes 20 to 30 minutes, and it pairs well with a walk to Reykjanes Lighthouse just 500 meters away.
Brimketill
A natural rock pool carved into the lava coastline by Atlantic waves, about 45 km from Reykjavik near Grindavik. In rough weather, waves crash over the pool. A viewing platform and short path from the parking area make it accessible in 10 to 15 minutes. Do not climb down to the rocks near the water, as rogue waves are powerful and unpredictable. It is most impressive during winter storms or when westerly swells are running.
Bridge Between Continents
A small footbridge spanning the rift between the North American and Eurasian tectonic plates, located about 42 km southwest of Reykjavik near Sandvik. The Mid-Atlantic Ridge surfaces here, and the plates drift apart at roughly 2 cm per year. The bridge itself is a quick 5 to 10 minute stop, with a lava field and interpretive signs around it. There is a visitor certificate available at the site.
Blue Lagoon
Iceland's most famous geothermal spa, fed by mineral-rich water from the Svartsengi power plant at 37 to 40 degrees Celsius. Located about 45 km (40 minutes) from Reykjavik and just 20 minutes from Keflavik Airport. The milky blue-white color comes from silica, algae, and mineral salts. Pre-booking is mandatory and peak times (10 am to 2 pm) sell out weeks ahead in summer. Plan 2 to 3 hours for the visit, and consider the less crowded late-afternoon or evening slots.
Fagradalsfjall eruption sites
The volcanic eruptions that began in 2021 at Fagradalsfjall ended roughly 800 years of dormancy on the peninsula and created new lava fields you can hike to. Fresh, dark lava contrasts with older moss-covered flows in a landscape that is still evolving. Access depends on current activity and trail conditions, so check SafeTravel.is before setting out and respect all closures around active or restricted zones.
Reykjanesviti Lighthouse
Iceland's oldest lighthouse site, on a hill above the coastal cliffs near the peninsula's southwestern tip; the first lighthouse in Iceland was raised here in 1878. Nearby Valahnukamol beach has wave-battered rock formations, and the Gunnuhver geothermal area is just 500 meters away, an easy combined stop.
Krýsuvík–Seltún geothermal area
A colourful geothermal field with bubbling mud pots, steaming fumaroles, and mineral-stained earth in vivid yellows, reds, and greens. Free to visit with boardwalk access, it sits along Route 42 in the peninsula's interior and pairs well with the Krysuvikurberg sea cliffs. As at Gunnuhver, stay strictly on the boardwalks.
