Where is the Krýsuvik Geothermal Area?

Krýsuvík is located in southwest Iceland on the Reykjanes Peninsula. It sits south of Reykjavík, near Lake Kleifarvatn and Route 42. The area is part of a larger volcanic and geothermal system that stretches across the peninsula.

Krýsuvík is close enough to Reykjavík for a half-day trip. But it also works well as part of a full Reykjanes Peninsula itinerary. Many travelers combine it with other Reykjanes Peninsula attractions, such as Lake Kleifarvatn, Blue Lagoon, or Gunnuhver Hot Springs.

The Geology Behind the Landscape of Krýsuvik

Krýsuvík is part of Iceland’s active volcanic landscape. The Reykjanes Peninsula sits along the Mid-Atlantic Ridge, where the North American and Eurasian tectonic plates are slowly moving apart. This movement creates fractures in the Earth’s crust and allows heat from below to influence the surface.

At Krýsuvík, water seeps underground, heats up, and rises again through cracks and geothermal channels. When it reaches the surface, it appears as steam vents, mud pots, hot springs, and warm mineral-rich ground.

The colors at Krýsuvík come from minerals and geothermal alteration. Yellow tones often come from sulfur. Red and orange shades are linked to iron-rich minerals. White, gray, and pale green areas can appear where clay and silica-rich deposits form.

This is why the landscape looks so varied in a small area. You may see steaming slopes, bubbling mud, and bright mineral patches all within a short walk.

It’s also why visitors need to stay on marked paths. Geothermal ground can be thin, unstable, and extremely hot beneath the surface. What looks like solid earth may be a fragile crust over boiling water, steam, or mud.

Top Attractions in Krýsuvík Geothermal Area

Krýsuvík isn’t just one single viewpoint. It includes several geothermal features and nearby natural landmarks. The main places to explore are:

Seltún: The main visitor area, with boardwalks, steaming vents, colorful hills, mud pots, and easy parking.
Fúlipollur: A notable geothermal pool in the wider Krýsuvík area. Its name roughly refers to a “foul-smelling pool,” a reminder of the strong sulfur smell common in active geothermal zones.
Hverahlíð: Features hot springs at the southern side of Lake Kleifarvatn. It’s less developed for casual visitors than Seltún, but it adds to the region’s geological interest.

For most travelers, Seltún will be the main stop. It offers the easiest access, the clearest walking route, and the best introduction to the area’s geothermal activity.

Exploring the Seltún Geothermal Area

Seltún is the highlight of Krýsuvík and the reason most visitors come here. It’s a compact but impressive geothermal field where you can safely walk through an active landscape on designated paths.

The first thing you may notice is the smell of sulfur. This is normal in geothermal areas and is often described as similar to rotten eggs. The smell is very noticeable, but it’s usually manageable during a short visit.

From the parking area, boardwalks and marked paths guide you through the site. There are also informational boards you can check out during your visit. Along the way, you can see steaming fumaroles, bubbling mud pots, colorful slopes, and small hot springs. The terrain changes quickly, and the steam gives the area a dramatic look even on cloudy days.

Seltún is especially good for photography. The colors are strong, the steam adds movement, and the surrounding hills provide a rugged backdrop. Overcast weather can actually be helpful. It reduces harsh glare and brings out the reds, yellows, greens, and grays in the mineral deposits.

A short visit may take 30 minutes. If you want to take photos, read signs, and walk slightly higher for wider views, allow 60–90 minutes.

Accessibility & Hiking Around Krýsuvik

Krýsuvík is one of the easier geothermal areas to visit on the Reykjanes Peninsula, but accessibility varies by section.

At Seltún, parking is close to the geothermal field. The main boardwalk makes it possible to see the key features without a long hike. However, surfaces can be uneven, slippery, or affected by weather. Snow, ice, rain, and wind can make the area more challenging.

Visitors with limited mobility may be able to enjoy parts of the main viewing area. However, the full route may not be suitable for all wheelchairs or strollers. Conditions can change, so it’s best to assess the path on arrival.

For hikers, the surrounding hills and ridges offer wider views over the geothermal area and nearby landscapes. Trails may be narrow, muddy, or steep in places. Good shoes are recommended, even for short walks.

Important: Do not leave marked paths to get closer to steam vents or mud pools. The ground in geothermal areas can be unstable and dangerous.

Facilities Around Krýsuvik Geothermal Area

While facilities at Krýsuvík are limited, visitors will find the essentials near the main attractions:

Parking: A paid parking lot is available next to the Seltún geothermal area. Payment can be made through the EasyPark or Parka app. Free parking is also available at Fúlipollur and Lake Grænavatn.
Toilets: Public restrooms are located near the parking area at Seltún.

There are no restaurants, cafés, or visitor centers on-site. So, it's a good idea to bring water and any supplies you may need for your visit.

How to Get to Krýsuvik Geothermal Area

Krýsuvík is easiest to reach by car or guided tour. Public transportation is limited, so planning ahead matters.

By car

Driving is the most convenient way to visit Krýsuvík. From Reykjavík, the trip usually takes around 40–50 minutes, depending on traffic, weather, and route.

Most visitors drive toward Hafnarfjörður and continue onto roads leading toward Lake Kleifarvatn and Route 42. The drive is scenic, with lava fields, mountains, lake views, and open Reykjanes landscapes along the way.

Paid parking is available near Seltún.

By guided tour

A guided tour is a good option if you don’t want to rent a car or drive in Icelandic weather. Tours around Reykjanes Peninsula may include Krýsuvík, Lake Kleifarvatn, Gunnuhver Hot Springs, coastal viewpoints, and other geological stops.

A guided experience can also add context. Krýsuvík is much more interesting when you understand the tectonic setting, geothermal activity, and safety considerations.

If you want a stress-free visit, look for a Reykjanes Peninsula day tour that specifically lists Krýsuvík in the itinerary.

Best Time to Visit the Krýsuvik Geothermal Area

Krýsuvík can be visited year-round, but each season offers a different experience:

Summer (June–August): Long daylight hours, milder temperatures, and easier driving conditions make summer one of the most popular times to visit. It’s ideal for combining Krýsuvík with hiking, photography, and other attractions around the Reykjanes Peninsula.
Fall (September–October): Fall brings quieter trails and excellent photography opportunities. The combination of steam, changing weather, and softer light often enhances the area's dramatic appearance.
Winter (November–March): Snow-covered hills and steaming geothermal features create a striking contrast. However, visitors should be prepared for icy paths, reduced visibility, and potentially challenging road conditions.
