Grettislaug: The Outlaw's Hot Tub

Hidden along Iceland's rugged Skagafjörður coast, Grettislaug stands as one of the country's most atmospheric geothermal bathing spots—a windswept hot tub perched on black rocks where legendary outlaw Grettir Ásmundarson once warmed himself after swimming from the fortress island of Drangey. This remarkable natural pool combines Iceland's geological wonders with its rich saga heritage, offering visitors a chance to bathe in waters steeped in both volcanic heat and medieval legend.

The Legend Behind the Pool

Grettislaug derives its name from Grettis saga Ásmundarsonar, one of Iceland's most celebrated medieval sagas. According to the 14th-century text, the mighty outlaw Grettir the Strong lived in exile on Drangey island for three years during the early 11th century. The saga tells of Grettir's incredible feat of swimming the 7.5 kilometres from Drangey to the mainland through the frigid waters of Skagafjörður bay—a journey that would challenge even modern cold-water swimmers wearing wetsuits.

Upon reaching shore, the saga describes how Grettir warmed his near-frozen body in natural hot springs before making the return swim to his island stronghold. While scholars debate the historical accuracy of this particular episode, the hot spring that bears Grettir's name has bubbled from the earth for centuries, creating a tangible link between Iceland's geological present and its literary past.

The original saga describes Grettir as possessing supernatural strength, capable of lifting boulders and swimming distances that would kill ordinary men. Whether fact or embellished folklore, the story captures the harsh reality of medieval Iceland, where survival often depended on intimate knowledge of the landscape's hidden resources—including its life-saving hot springs.

Geological Origins and Features

Grettislaug sits within Iceland's active volcanic zone, where the Mid-Atlantic Ridge creates constant geothermal activity. The spring emerges from basalt bedrock formed during volcanic eruptions over thousands of years, with mineral-rich water heated by magma chambers deep below the surface. The water temperature typically ranges between 38-40°C, making it ideal for extended soaking even during Iceland's harsh winters.

The pool itself has been enhanced with concrete walls to contain the naturally flowing spring water, creating a roughly circular bathing area approximately 4 metres in diameter. Unlike heavily developed geothermal facilities, Grettislaug maintains its wild character—the surrounding landscape remains largely untouched, with only basic wooden decking and changing facilities added for visitor comfort.

The spring water contains elevated levels of silica, sulphur, and various minerals typical of Icelandic geothermal systems. While not as heavily mineralised as some of the country's famous blue lagoons, the water possesses the characteristic slightly milky appearance and soft feel of geothermal springs. The natural flow-through system ensures the water remains clean and fresh without chemical treatment.

Location and Access

Grettislaug is located near the village of Reykir in Skagafjörður, approximately 45 kilometres north of Varmahlíð along Route 1, then 15 kilometres west on Route 748. The final approach requires a 2-kilometre drive on a gravel road suitable for most vehicles, though a 4x4 provides additional comfort over the rougher sections.

From Reykjavík, the journey covers roughly 250 kilometres and takes about 3 hours via the Ring Road. The route passes through some of Iceland's most dramatic highland scenery, including views of Langjökull glacier and the volcanic peaks of the Interior. Many visitors combine Grettislaug with other Skagafjörður attractions, including the historic Glaumbær turf farm museum and the horse-breeding centres around Sauðárkrókur.

The final kilometre to the pool involves a short walk from the car park across uneven coastal terrain. The path is generally well-marked but can be challenging in wet conditions, as the volcanic rock becomes extremely slippery. Sturdy footwear is essential, particularly during winter months when ice formation is common.

The Bathing Experience

Unlike Iceland's commercial geothermal facilities, Grettislaug offers an entirely unfiltered encounter with the country's natural forces. The pool sits directly on the coastline, meaning bathers enjoy unobstructed views across Skagafjörður bay to the dramatic silhouette of Drangey island—the very route Grettir supposedly swam a thousand years ago.

The contrast between the warm spring water and the often fierce North Atlantic weather creates an intensely memorable experience. Winter visits can be particularly dramatic, with snow-covered cliffs providing a stark backdrop while northern winds whip across the exposed coastline. The hot spring provides a natural refuge from these elements, explaining why it proved so crucial to Grettir's survival.

Basic changing facilities consist of a small wooden structure providing minimal shelter from wind and weather. Visitors should come prepared with warm clothing and waterproof gear, as conditions can change rapidly along this exposed stretch of coast. The lack of amenities is intentional—Grettislaug remains deliberately undeveloped to preserve its wild character.

Practical Information and Planning

Grettislaug requires no entrance fee, though a small donation box helps fund basic maintenance of the access path and facilities. The pool is accessible year-round, but conditions vary dramatically by season. Summer visits (June-August) offer the most comfortable access and extended daylight hours, while winter soaking provides the chance to witness the northern lights from the warm water.

The best visiting times are typically early morning or late afternoon, when lighting conditions enhance the dramatic coastal scenery and visitor numbers remain manageable. The pool can accommodate roughly 6-8 people comfortably, though most visitors prefer more intimate groups of 2-4 bathers.

Essential items include swimwear, towels, warm clothing for before and after bathing, and sturdy footwear for the coastal approach. A waterproof bag protects valuables from spray and weather, while a thermos of hot drink can prove invaluable during winter visits.

Respectful Visiting

Grettislaug's continued accessibility depends entirely on respectful visitor behaviour. The site operates on trust principles—no staff monitor the facility, and maintenance relies on user responsibility and voluntary donations. Visitors must pack out all waste, avoid disturbing the natural surroundings, and respect the pool's capacity limitations.

The spring's remote location and cultural significance deserve particular respect. This is not merely a tourist attraction but a landscape intimately connected to Iceland's literary heritage and geological character. Swimming in Grettir's legendary hot spring offers a profound connection to both Iceland's natural forces and its saga-age past—a reminder that the country's greatest treasures often lie in the marriage between landscape and story, heat and legend, ancient rock and timeless water.
