The Reykjanes Peninsula is one of the most geologically active regions in Iceland. Located near Keflavík International Airport, it offers a compact experience of the country’s volcanic landscapes, geothermal activity, and rugged coastline.

Many travelers pass through Reykjanes on their way to Reykjavík without realizing how much there is to see. From recent volcanic eruptions to steaming geothermal areas, the peninsula offers a clear view of the natural forces shaping Iceland.

Whether you’re visiting for a day or two, this guide covers the top things to do on the Reykjanes Peninsula. Plus, some practical tips to help you make the most of your time. So, shall we?

Explore Reykjanes’ Active Volcanic Landscape

The Reykjanes Peninsula has seen a renewed period of volcanic activity in recent years. The first eruption in this cycle began in March 2021 at Fagradalsfjall, marking the region’s first eruption in nearly 800 years.

Additional eruptions followed in 2022 and 2023, creating new lava fields and reshaping the terrain. More recent activity has shifted toward the Sundhnúkur crater row (2023–2025) near Grindavík, where fissures and lava flows have affected nearby areas.

Note: While eruptions aren’t constant, the peninsula remains an active volcanic zone. Experts continue to monitor conditions closely, and future eruptions are possible.

Touring the Fagradalsfjall Volcano area

The Fagradalsfjall Volcano area is now one of the most popular attractions on the Reykjanes Peninsula. Even without an active eruption, it offers a rare opportunity to explore newly formed lava fields and volcanic terrain.

There are several ways to explore the Fagradalsfjall eruption sites:

Guided hiking tours for structured routes and added safety
Super Jeep tours for access to more remote terrain and viewpoints
Helicopter flights for a full view of lava fields and crater systems

Safety reminder: Check official updates before visiting and follow marked trails at all times.

Visiting Grindavík

The town of Grindavík is located near recent volcanic eruption sites and is a practical stopover before or after a volcano tour. Even if you don’t visit the eruption sites directly, you can still see their effects within the town.

On Efrahóp Street, cooled lava from early 2024 extends toward residential areas. Three houses were damaged as it reached the edge of the street. At Salthúsið Restaurant, cracks caused by seismic activity run directly through the building’s floor, forcing it to close. These areas are barricaded for safety, but the extent of the damage remains visible from the street.

Beyond the affected sites, Grindavík also offers:

Local cafés and seafood restaurants
A scenic harbor area for coastal walks
Community facilities such as a public swimming pool

It’s a good place to understand how recent volcanic activity has changed the area. It also offers a chance to experience a more local side of the Reykjanes Peninsula.

Visit the Top Attractions in the Reykjanes Peninsula

The Reykjanes Peninsula offers a range of natural and cultural attractions, many of which are easy to visit in a single trip. From geothermal areas to coastal viewpoints, these sites highlight the region’s diverse landscapes and geological features.

1. Blue Lagoon

The Blue Lagoon is one of Iceland’s most well-known attractions. Set within a lava field near Grindavík, this geothermal spa is known for its milky-blue water and mineral-rich composition.

Despite its popularity, it remains a worthwhile stop, especially early in the morning or later in the evening when it’s less crowded. In addition to the main lagoon, it features saunas, steam rooms, and a range of in-water treatments.

Fun fact: The water in the Blue Lagoon comes from the runoff of the nearby Svartsengi Geothermal Power Station.

2. Bridge Between Continents

The Bridge Between Continents marks a symbolic crossing between the North American and Eurasian tectonic plates. While the physical gap is modest, the concept makes it a quick and interesting stop.

You can walk across the bridge and even pick up a certificate as a souvenir to mark your crossing between continents. It’s a short visit, but worth including in your route.

3. Gunnuhver Hot Springs

Gunnuhver is one of the most active geothermal areas on the Reykjanes Peninsula. Large steam vents and boiling mud pools release constant geothermal energy, which you can observe safely from designated viewing paths.

The area has a strong sulfur smell, often described as similar to eggs. The site is also tied to a local ghost story about Gunna, a restless spirit. According to legend, she was lured into the area around 400 years ago after causing great disturbance.

4. Valahnúkamöl

Valahnúkamöl is a rugged coastal area at the southernmost part of the Reykjanes Peninsula. It’s defined by a prominent boulder ridge shaped by volcanic activity and constant ocean exposure.

Waves regularly crash against the shoreline, creating a strong contrast with the dark lava formations. You can walk along the ridge for open coastal views and photo stops.

5. Reykjanes Lighthouse

Reykjanesviti, or Reykjanes Lighthouse, is the oldest lighthouse in Iceland and an easy stop along the way to Valahnúkamöl. The original structure, built in 1878, was destroyed by an earthquake, and the current lighthouse was rebuilt between 1907 and 1908.

It stands on a hill overlooking the coast, with a short walk to the top for wide views of the surroundings. At the base, the Reykjanesviti Exhibition & Visitor Center provides information about the lighthouse and nearby attractions.

6. Garður Old & New Lighthouses

At the northwestern tip of the Reykjanes Peninsula, the Garður Old Lighthouse offers a quieter stop with open coastal views. The original lighthouse sits close to the shore with a simple, boxy design.

A short walk away, the newer Garðskagi Lighthouse stands on a grassy field near local facilities. Built in 1944 and about 92 feet (28 meters) tall, it’s the tallest lighthouse in Iceland. You can enter and climb to the top for a view of the coastline.

7. Brimketill Lava Rock Pool

Brimketill is a natural lava rock pool shaped by strong Atlantic waves. From the parking area, a steel walkway leads to a viewing platform overlooking the pool.

While it may look inviting, this is not a place to swim. The waves are powerful and unpredictable, and during rough conditions, they can reach the platform. It’s best experienced as a viewing stop.

8. Seltún Geothermal Area

Located in the Krýsuvík area, Seltún is one of the most active geothermal sites on the Reykjanes Peninsula. Wooden walkways take you through steaming vents and bubbling mud pools. You’ll notice a strong sulfur smell, along with minerals that color the ground in shades of red, yellow, and blue.

It’s one of the most accessible geothermal areas on the peninsula and an easy stop to explore.

9. Lake Kleifarvatn

Lake Kleifarvatn is the largest lake on the Reykjanes Peninsula, covering about 3 sq mi (8 sq km). It reaches depths of up to 295 ft (90 m), making it one of the deepest lakes in Iceland.

The lake sits above geothermal systems, and its water levels have fluctuated due to past seismic activity. If you’re driving along Road 42, you’ll find several viewpoints where you can stop for elevated views of the lake.

Have plenty of time to explore? There are several things to do around Lake Kleifarvatnthat you can try.

Try Various Outdoor Experiences in Reykjanes

Beyond sightseeing, the Reykjanes Peninsula offers a variety of outdoor experiences. Here are some you can try during your visit.

1. Snorkeling at Lake Kleifarvatn

Speaking of Lake Kleifarvatn, you can also snorkel over hot springs here. The lake sits on the Mid-Atlantic Ridge, where geothermal activity creates underwater vents close to shore.

A central crater releases warm water and gases, producing steady bubbles that cause subtle vibrations. It’s a rare sensation you can feel as you float above the lake floor.
