Iceland’s Geothermal Wonderland: Reykjanes Peninsula

The Reykjanes Peninsula sits in southwest Iceland, forming the natural link between Reykjavík and Keflavík International Airport. It lies directly atop the Mid-Atlantic Ridge, the meeting point of the North American and Eurasian tectonic plates. This position makes it one of the most geologically active regions in the Land of Fire and Ice.

Here, the earth hums with life: steaming vents, bubbling mud pools, and moon-like craters shape a landscape that feels almost extraterrestrial. It’s eerie, yes; but also breathtakingly beautiful.

Despite its accessibility and natural wonders, Reykjanes is surprisingly underrated. Apart from the world-famous Blue Lagoon, you’ll find few crowds here. It’s just vast, untamed scenery where the sounds of nature outnumber the voices of travellers. If you’re seeking a bit of solitude and raw Icelandic beauty, then a Reykjanes excursion may be ideal.

Why Choose a Reykjanes Peninsula Self-Drive?

Unlike Iceland’s vast highlands or distant fjords, Reykjanes is compact enough to explore thoroughly on a single day. The main loop, which takes you to volcanic craters, steam vents, and tectonic boundaries, requires only about 2.5–3 hours of pure driving time. That leaves plenty of time to stop, stretch your legs, and soak in the scenery.

Accessibility is another major draw. Keflavík airport lies within the peninsula, while Reykjavík is a 45-minute drive away. Whether you’re planning a day trip from the capital, or a first- or last-day itinerary near the airport, Reykjanes is well-positioned. Even travellers on a long layover at KEF can squeeze in a rewarding circuit.

A self-drive trip lets you embrace the region’s atmospheric beauty at your own pace. Roads are well-maintained and easy to navigate, and distances are short enough for unhurried exploration. Behind the wheel of your MyCar rental, you can linger where the landscape calls, or veer off-route to uncover Reykjanes’ hidden corners.

Top Stops on the Reykjanes Peninsula

The Reykjanes Peninsula self-drive loop takes you across the Mid-Atlantic Ridge, where Iceland’s fiery geology meets the sea. Departing Reykjavík, drive along scenic roads such as Route 42 and Route 427 toward Krýsuvík’s geothermal fields and lava plains beyond. From there, Route 425 leads you west to dramatic ocean viewpoints before looping back toward the capital via Route 41.

Lake Kleifarvatn

From Reykjavík, your journey begins at the serene and mystical Lake Kleifarvatn, the peninsula's largest lake. Surrounded by dark volcanic mountains, this is an excellent first stop to appreciate the region’s scale and solitude. Local legend whispers of a giant, worm-like serpent lurking in its dark waters, adding to the lake’s mystique. Easily accessible from Route 42, Kleifarvatn offers several pull-offs perfect for panoramic photos.

Seltún Geothermal Area (Krýsuvík)

In stark contrast to the still waters of Kleifarvatn, Seltún bursts with colour and energy. This intensely active geothermal field showcases the raw power simmering beneath Reykjanes’ surface. Wooden boardwalks lead visitors past bubbling mud pots and hissing fumaroles that veil the landscape in steam.

Around you, mineral-stained hills glow in vivid shades of ochre, red, and green. Seltún is not only one of the peninsula’s most easily accessible geothermal sites but also one of the most photogenic.

Fagradalsfjall Volcanic Area

Few experiences capture Iceland’s raw power like standing on the site of a recent eruption. At Fagradalsfjall, part of the Reykjanes volcanic system, the once-molten flows from 2021, 2022, and 2023 have solidified into vast, jet-black fields of fresh lava.

Well-marked trails lead to viewing points where you can take in the immense, otherworldly landscape. This stop is a humbling encounter with the mighty forces that continue to shape Iceland, both seen and unseen.

Brimketill Lava Rock Pool

The striking Brimketill rock pool was carved over centuries by the relentless crashing of waves on the soft lava cliffs. It is a mesmerising sight to watch the huge, dark Atlantic waves engulf the pool, only for the water to drain away seconds later, leaving a crystalline surface. Local folklore states this pool was once the bathing spot of the giantess, Oddný, adding a layer of mystique to this wild, windswept coastal view.

Gunnuhver Geothermal Area

A spectacle showcasing the Reykjanes Peninsula's intense geothermal energy, Gunnuhver is easily identified by its enormous cloud of steam. This is, after all, one of Iceland's most active geothermal fields. Gunnuhver is home to the country’s largest mud pool, a violently boiling cauldron of earth and seawater. Its name comes from the tale of Gunna, an angry ghost who was supposedly trapped here by a priest centuries ago.

Reykjanesviti Lighthouse & Valahnúkamöl Cliffs

At the far southwestern tip of the peninsula stands Reykjanesviti, Iceland’s oldest operating lighthouse. Perched on a windswept hill overlooking the Atlantic, it has guided ships since 1907. Just below lie the Valahnúkamöl Cliffs, a stunning coastal stretch famous for its towering black basalt stacks.

In summer, the cliffs come alive with seabirds nesting along the ledges. Look for the poignant great auk sculpture. The memorial is a tribute to the extinct bird whose final breeding pair was killed on the nearby Eldey Island.

Bridge Between the Continents

This stop is a fun, symbolic landmark marking a spot where the Mid-Atlantic Ridge is clearly visible above the surface. Named after explorer Leif Eiriksson, the modest footbridge spans a rift valley that separates the North American and Eurasian tectonic plates. It’s one of the few places on Earth where you can jump from one continent to another in a single step!

Blue Lagoon

Your Reykjanes Peninsula self-drive concludes at the Blue Lagoon, Iceland’s most iconic attraction and the perfect finale to your adventure. This world-renowned geothermal spa is known for its milky-blue, mineral-rich waters that shimmer against the dark volcanic landscape.

It’s the ideal place to relax, rejuvenate, and soak away the miles of the road. Just be sure to reserve your entry well in advance, as this geothermal oasis is almost always in high demand.

Driving Tips and Road Conditions for a Reykjanes Peninsula Self-Drive

Even if you’re planning to stick to paved roads and major attractions, the Icelandic environment calls for caution and preparation. Here are several essential tips before you hit the road for your day-long adventure.

• Prepare for Road Quality: The main routes in Reykjanes are well-maintained, two-lane paved roads. Like much of rural Iceland, however, they often have no paved shoulder. If you need to stop, use designated pull-off areas only.
• Pick the Right Vehicle: For the main attractions, a standard two-wheel-drive vehicle from MyCar is perfectly adequate. If you plan to explore rougher tracks or travel during winter, a 4x4 rental is strongly recommended.
• Keep an Eye on the Conditions: Iceland's weather and road conditions can change rapidly. Always check the official sites road.is (for road status) and vedur.is (for weather forecasts).
• Always Use Headlights: By law, headlights must be on 24 hours a day, even in bright daylight.
• Fuel Up When You Can: Gas stations are mainly found in Reykjanesbær (Keflavík/Njarðvík) and Grindavík. Refill whenever your tank reaches half, as options are limited elsewhere.
• Plan for Limited Connectivity: Mobile coverage can drop near the coast and in lava fields. Download offline maps for the region before leaving your hotel or rental base.
• Respect the Landscape: Off-road driving is illegal and carries heavy fines. Always stay on marked roads and trails. Tyre tracks can scar fragile moss and lava for decades.
• Start Your Day Early: To comfortably fit all major stops, especially if you have a pre-booked Blue Lagoon entry, aim to begin your day trip no later than 9 am.
• Pack Essentials: Bring snacks and drinks. Cafés and restaurants are limited outside the main towns, and having supplies on hand helps you stay flexible.
• Connect Your Tour: The Reykjanes Peninsula works beautifully as a stand-alone day trip, but it’s also the perfect start or finish to a South Coast, Golden Circle, or full Ring Road itinerary.
