Iceland’s landscape is unlike any other in the world. It is shaped by centuries of volcanic activity, from grand peaks to cascading waterfalls, and shows the power of nature’s raw force. In this article, we’ll explore volcanic eruptions in Iceland, with a focus on the Litli Hrútur Mountain region. While currently dormant, Litli-Hrútur offers a glimpse into Iceland’s volcanic past through its unique geology.

This comprehensive guide delves into the history of the Reykjanes peninsula’s fiery activity, equipping you with the knowledge you need to plan a safe and unforgettable journey to Litli-Hrútur.

About Litli-Hrútur mountain in Iceland

Litli-Hrútur is a mountain on Iceland’s Reykjanes Peninsula with a geological significance that extends beyond its peak. The mountain stands 1024 feet (312 meters) tall and is part of the volcanic belt. In July 2023, a fissure eruption near the mountain fractured the earth for nearly a kilometer, spewing lava and ash.

This attracted considerable attention from scientists, volcanologists, and enthusiasts, who closely monitored the eruption to better understand Iceland’s volcanic activity and its impact on the environment. Although the eruption posed potential hazards to local communities and the ecosystem, it provided valuable scientific data that can be used to predict and prepare for further volcanoes. 

The eruption also serves as a reminder of Iceland’s position on the Mid-Atlantic Ridge, where tectonic plates are continuously pulling apart, causing ongoing volcanic activity. Litli-Hrútur’s location within the Fagradalsfjall volcanic area offers visitors a chance to witness firsthand the dramatic landscapes sculpted by volcanic processes. Litli-Hrútur holds both scientific and cultural importance, attracting both adventurers and researchers interested in Iceland’s geological history.

Update on Litli Hrútur Mountain: 2023 Eruption and Current Visitor Information

In the summer of 2023, Iceland’s Reykjanes Peninsula experienced a significant geological event when the Litli Hrútur volcano erupted. The eruption commenced on July 10, 2023, at approximately 5 PM local time, following a series of earthquakes in the area. The fissure extended about 900 meters, releasing substantial lava flows and volcanic gases. This event continued until early August 2023, with the Icelandic Meteorological Office declaring the eruption over by August 5, 2023.

As of February 2025, Litli Hrútur remains dormant. Visitors to the area can observe the expansive lava fields and unique geological formations resulting from the 2023 eruption. These features offer a tangible insight into the dynamic volcanic activity that characterizes Iceland’s landscape.

Litli-Hrútur is NOT actively erupting at present, but its volcanic past is evident in the surrounding landscape. Look for volcanic rock formations, lava fields, and dormant craters that have been sculpted by the lava flows in this area.

With the tectonic plates continuing to move, future eruptions are definitely a possibility, so it’s important to continuously monitor the zone and remain prepared for when they happen.

How close is the lava in Iceland to Keflavik

The lava fields from the 3-week eruption near Litli-Hrútur in July 2023 are about 20 kilometers (12 miles) from Keflavík International Airport. Despite being relatively close, the airport’s operations were not affected during the eruption.

How to get to Litli hrutur mountain?

Litli-Hrútur mountain is conveniently accessible from the capital city of Reykjavik, situated approximately 40.6 kilometers (25.2 miles) away. You’ll need to drive south out of the city on Route 40, as opposed to the Route 1 Ring Road, which is a more common route for travelers exploring the country.

Visitors often opt to rent a car in Iceland for a scenic 1-hour drive as Litli-Hrútur mountain is located in a remote or less developed area. Travelers prefer this method of transportation, as it provides the flexibility to explore at their own pace. You can easily access one of the two designated parking areas by taking Road 427, which branches off Route 41, on the way to Grindavik.

From the parking lot, you will need to hike the rest of the way to get to the viewing points of the Litli-Hrútur mountain itself. One of the most popular hiking routes to view the mountain is D-trail, aka Merardalir Leid. The path is about 20 kilometers (12 miles), so be prepared for a moderately challenging hike. 

Hiking to Litli Hrútur: Path E

For those interested in exploring the site, Path E (Meradalir) is the designated trail leading to the eruption area near Mt. Litli Hrútur. This trail spans approximately 18-20 kilometers round trip and is considered challenging, typically requiring 5-6 hours to complete, excluding time spent at the site. The initial segment of the hike follows a gravel path, transitioning to moss-covered lava rocks in the final 2 kilometers. Hikers are advised to assess their fitness levels before attempting this trek and to be prepared for varying terrain and weather conditions.

There is no public transportation to the trailheads, so renting a car is the most recommended way to get there. Some guided tours are also available from Reykjavik, which will take you to the general area around Litli-Hrútur.

Access and Parking

The trailhead for Path E is accessible from Road 427, east of Grindavík. Visitors should park at the designated Parking 2 (P2) area, as off-road driving is prohibited to protect the delicate environment. A parking fee of 1000 ISK per vehicle applies, payable via the Parka app.

Safety Guidelines

When visiting the Litli Hrútur area, safety should be a top priority:

  • Stay Informed: Before your trip, consult official sources such as road.is for road conditions and vedur.is for weather updates.
  • Stick to Marked Trails: To minimize environmental impact and ensure personal safety, remain on designated paths.
  • Avoid New Lava Fields: Refrain from walking on new lava formations, as they can be unstable and hazardous.
  • Prepare Adequately: Icelandic weather is notoriously unpredictable. Equip yourself with appropriate clothing, sturdy hiking boots, and sufficient supplies.

Best rental car option for this trip

For your trip to Litli-Hrútur mountain, selecting a 4X4 SUV rental is highly recommended, especially given the abundance of gravel roads in the area. A 4×4 SUV provides the traction and stability necessary to navigate rugged terrain, enhancing safety during your travels.

Regardless of the season, having a 4X4 vehicle is key, as you will be required to venture off main roads to access mountainous regions. Gravel roads, commonly found in remote areas of Iceland, can pose challenges for 2WD vehicles due to limited traction and ground clearance.

By choosing a 4X4 SUV, you’ll feel more confident navigating off-road paths, ensuring a comfortable and safe journey to Litli-Hrútur mountain and enabling you to fully enjoy your travels along the way.
