Discover the Best Reykjanes Peninsula Things to Do

The moment you land at Keflavík International Airport (KEF), the urge to hit the Ring Road ASAP is powerful. Many travelers make a beeline for the Golden Circle or the South Coast, treating the Reykjanes Peninsula as a mere gateway. But why rush? This rugged corner of Iceland is a goldmine for adventurers.

When looking for Reykjanes Peninsula things to do, you’ll find the options run the gamut: from total relaxation to intense excursions. Expect sweeping craters, steaming geothermal vents, and crashing Atlantic waves, many without an entrance fee. Indeed, the Reykjanes Peninsula proves that some of Iceland’s best experiences start the second you leave the airport.

1.  Soak in the Mineral-Rich Blue Lagoon

The Blue Lagoon is easily the most iconic of all Reykjanes Peninsula things to do. Lying in a pitch-black lava field, its milky-blue waters are world-famous for their healing properties. The vivid blue water is rich in silica and algae, and it looks especially surreal when shrouded in morning mist.

A soak in the Blue Lagoon is a quintessential Icelandic experience. Every tourist has it on their list, so you must book your spa admission well in advance. If you prefer to save your budget, a free walking path near the parking lot winds through the lava fields.

2. Walk Between Continents

At the Bridge Between Continents, you can actually walk across the tectonic rift separating North America and Eurasia. This symbolic footbridge arches over a fissure caused by the tectonic plates drifting by about two centimeters each year.

Located around 20 minutes from the airport, the bridge is an easy addition to any self-drive Iceland itinerary. It is a 100% free stop, a rare opportunity to “stand in two places at once.” Be sure to walk under the bridge as well. From there, you can look up at the bridge from the rift floor, a more dramatic composition for your Instagram picture.

3. Witness the Power of Gunnuhver

Gunnuhver is a high-temperature geothermal area churning with activity. It features Iceland’s largest mud pool, a 65-foot (20-meter) wide cauldron of boiling gray-blue clay. Unlike other springs in Iceland, the water here is 100% seawater. This creates a unique cocktail of minerals that paint the earth in vivid shades of rust and sulfur.

Walking the sturdy wooden boardwalks allows you to experience the roar of the vents safely. Local legend says the area is haunted by a ghost named Gunna, adding a layer of folklore to your visit.

4. Visit Iceland’s Oldest Lighthouse Site

A short drive from Gunnuhver leads to an iconic coastal duo: the Reykjanesviti Lighthouse and the Valahnúkamöl Cliffs. Reykjanesviti is a striking white tower capped with a red lantern, standing atop Bæjarfell hill. This also marks the site of Iceland’s very first lighthouse.

Just steps away, the landscape drops into the Atlantic at the Valahnúkamöl cliffs. This is a geological rarity: a ridge made of millions of smooth, well-rounded stones polished by centuries of powerful surf. Just offshore, the 195-foot (60-meter) sea stack Karlinn rises out of the ocean.

5. Marvel at New Lava Sites

Since 2021, the Reykjanes Peninsula has entered a new volcanic era. Major eruptions at Fagradalsfjall and the Sundhnúkur crater row reshaping the land. These present one of the most powerful Reykjanes Peninsula things to do: the chance to see the Earth’s youngest crust. The vast, obsidian-black fields of lava may still be steaming from residual heat.

For a steady hike, head to the Fagradalsfjall area. Trails here lead you to the 2021 and 2022 lava flows, which are now stable enough for viewing from the path. For the most recent activity, viewing is often restricted to designated roadside pull-offs or organized tours.

6. Discover the Colorful Seltún Geothermal Area

Located within the Krýsuvík volcanic system, Seltún is a kaleidoscope of geothermal activity. Wooden boardwalks lead you safely past bubbling mud pots and steaming fumaroles. The ground is a natural canvas, painted by minerals in yellow, red, and green. The sharp scent of minerals (often compared to rotten eggs) lingers in the air, adding to the alien-like atmosphere.

As you walk the path up the hillside, you’ll be rewarded with a panoramic view of the steaming vents. It’s even more striking against the backdrop of the deep blue Kleifarvatn lake in the distance.

7. Reflect at Lake Kleifarvatn

Kleifarvatn is the largest lake on the peninsula with a stark, surreal beauty that leaves a big impression. Surrounded by black sand beaches and volcanic slopes, the lake has a still atmosphere that gives campers a much-needed breather. It’s extra eerie because the lake has no visible surface inlets or outlets. Instead, its water levels rely on groundwater.

There are several free pull-offs along Route 42 where you can park and hike down to the water’s edge. Keep an eye out for Kleifarvatn Monster, a legendary, whale-sized serpent believed to live in these depths.

8. Stand on the Edge at Krýsuvíkurbjarg

The South Coast is famous for its cliffs, but for a quieter alternative, head to the Krýsuvíkurbjarg bird cliffs. Here, sheer volcanic walls drop over 160 feet (48 meters) into the wild Atlantic. During summer, these bird cliffs become a thriving nesting ground for thousands of seabirds like fulmars, razorbills, and kittiwakes. If you have a keen eye, you can even spot small colonies of Atlantic puffins.

There is no entrance fee, and the sense of isolation makes it a highlight among things to do in Reykjanes Peninsula. Note that the bumpy gravel road leading to the cliffs is best suited for a rental car with decent clearance. Still, the wildlife, views, and sunset photography opportunities make it well worth the drive. 

9. Explore the Lava Town of Hafnarfjörður

Known as the town built in the lava, Hafnarfjörður seamlessly bridges the capital and the peninsula’s wilder side. Across town you’ll find moss-covered lava formations tucked between modern houses and traditional timber buildings. 

And if you’re here, a visit to Hellisgerði Park is a must. These gardens are filled with volcanic caves and crags said to be the homes of the Huldufólk (hidden people or elves). Afterward, head to the bustling harbor or visit the Hafnarborg Center of Culture and Fine Art for the local creative scene.

10. Watch the Waves at Brimketill

Sitting at the base of a cliff on the Atlantic’s edge is Brimketill, a natural pool carved by the relentless surf. It’s a mesmerizing sight, especially when the tide is high and the waves thunder against the cliffs. According to local folklore, the pool was the private bathing spot of a giantess named Oddný. Legend has it she stayed too long in the water one night and was turned to stone by the first rays of the morning sun.

While the turquoise water inside the cauldron looks tempting, it’s no place for a swim. The water is freezing, and the “sneaker waves” are powerful enough to sweep a person off the rocks suddenly. Always stay on the designated wooden viewing platform. 

Stay Close to the Action at Konvin Hotel

When planning your adventure, choosing a strategic base is key. Konvin Hotel is located just minutes from Keflavík International Airport, making it the perfect starting or ending point for your journey. Its central location allows you to easily reach all the major Reykjanes Peninsula things to do in a single day. 

For travelers in a rental car or campervan, the hotel offers free parking and a morning shuttle to the airport. Spending your last night here ensures a hot shower and a comfortable bed before your flight, no matter how early.
