South Coast Drive: Waterfalls, Glaciers and Black Beaches

Iceland's South Coast represents perhaps the most concentrated showcase of the island's geological drama. This 370-kilometre stretch from Reykjavík to Jökulsárlón glacier lagoon packs more natural wonders per kilometre than virtually anywhere else on Earth. The Route 1 Ring Road serves as your highway through landscapes that shift from emerald farmland to volcanic black sand beaches, past thundering waterfalls and glacier tongues that seem to pour directly from another world.

The South Coast drive stands as Iceland's most popular road trip for good reason. Unlike the challenging Highland routes that require 4WD vehicles and careful timing, this journey follows well-maintained tarmac accessible year-round to standard vehicles. Yet accessibility doesn't diminish the raw power of what you'll witness—active volcanoes, retreating glaciers, and some of the most photographed waterfalls on the planet.

The Waterfall Trinity: Seljalandsfoss, Gljúfrabúi and Skógafoss

Your first major stop arrives 128 kilometres southeast of Reykjavík at Seljalandsfoss, where the Seljalandsá River plunges 60 metres over what was once Iceland's southern coastline. The clifftop stood at the ocean's edge during the last ice age; today, it towers 5 kilometres inland thanks to centuries of sediment deposits.

Seljalandsfoss offers something unique among major waterfalls—a complete walking path behind the cascade. The 1.2-kilometre trail requires sturdy footwear and waterproof clothing, as the spray creates perpetual mist that can soak visitors within seconds. Winter visits demand particular caution, as ice formations can make the path treacherous.

Hidden just 600 metres northeast lies Gljúfrabúi, the "Canyon Dweller," concealed within a narrow rock fissure. This 40-metre waterfall remains invisible until you wade through the shallow stream at the canyon's entrance. Many visitors miss this spectacular hidden gem entirely, making it feel like a private discovery despite its proximity to the crowded main attraction.

Continuing 30 kilometres east brings you to Skógafoss, arguably Iceland's most photogenic waterfall. The Skógá River drops 60 metres over a sheer cliff face that spans 25 metres in width, creating a thunderous roar audible from over a kilometre away. On sunny days, the perpetual spray generates vivid rainbows that dance across the mist.

The Skógafoss staircase—527 steps carved into the eastern cliff face—leads to a viewing platform directly above the falls. The climb proves demanding but rewards with views across the Eyjafjallajökull glacier and the coastal plain stretching to the Westman Islands.

Volcanic Drama: Eyjafjallajökull and Katla

The South Coast drive passes directly beneath two of Iceland's most notorious volcanic systems. Eyjafjallajökull, despite its tongue-twisting name meaning "Island Mountain Glacier," gained global recognition in 2010 when its eruption grounded European air traffic for six days. The 1,666-metre peak sits atop a volcano that has erupted three times in recorded history—1821, 1823, and 2010.

From the Ring Road near Skógar, Eyjafjallajökull appears deceptively peaceful, its summit ice cap glinting white against the sky. Yet beneath that 100-square-kilometre glacier lies an active magma chamber that volcanologists monitor continuously.

Even more threatening looms Katla, hidden beneath the vast Mýrdalsjökull ice cap visible to the south. This massive volcanic system has erupted roughly every 40-100 years throughout recorded history, with the last major eruption occurring in 1918. When Katla eventually awakens—and geological evidence suggests it will—the eruption could dwarf Eyjafjallajökull's impact by orders of magnitude.

Black Beach Majesty: Reynisfjara and Beyond

The South Coast's most otherworldly landscape unfolds at Reynisfjara, near the village of Vík í Mýrdal. This black sand beach, formed from volcanic glass fragments pulverised by millennia of Atlantic storms, stretches beneath towering basalt columns that rise like a natural cathedral.

The Reynisdrangar sea stacks—three pointed pillars standing 66 metres offshore—feature prominently in Icelandic folklore as trolls caught by sunrise and turned to stone. Geological reality proves equally dramatic: these formations represent the remnants of a volcanic plug, harder rock that resisted erosion while softer material washed away.

Reynisfjara demands serious respect from visitors. The beach experiences "sneaker waves"—unpredictable surges that can reach 50 metres inland without warning. These powerful walls of water have proven fatal to unwary tourists. Always maintain significant distance from the waterline and never turn your back on the ocean.

The nearby Garðar cliffs showcase Iceland's geological layering in stunning detail. Here, multiple lava flows from different eruptions have created distinct horizontal bands, each representing thousands of years of volcanic activity.

Glacier Encounters: Sólheimajökull and Mýrdalsjökull

At Sólheimajökull, 8 kilometres north of the Ring Road near Skógar, visitors can approach an active glacier tongue without specialised equipment. This outlet glacier of Mýrdalsjökull has retreated dramatically—over 1 kilometre since 1930—leaving behind a proglacial lagoon dotted with small icebergs.

The 1.5-kilometre walk to the glacier snout crosses a landscape of glacial moraines and meltwater channels that demonstrate ice's tremendous erosive power. The glacier ice appears brilliant blue where compressed, with dark streaks of volcanic ash from historical eruptions embedded in the ice layers.

Guided glacier walks operate year-round (ISK 12,900 for adults), providing crampons and ice axes for safe exploration of the glacier surface. These tours reveal crevasses, ice caves, and the dynamic nature of glacial ice that constantly shifts and cracks.

Planning Your South Coast Adventure

The complete drive from Reykjavík to Jökulsárlón requires a full day, though most visitors prefer to split the journey with an overnight stay in Vík or Höfn. Fuel stations appear regularly—at Selfoss (54km), Hvolsvöllur (106km), Vík (186km), and Kirkjubæjarklaustur (261km).

Summer offers the most comfortable driving conditions and longest daylight hours, with some areas accessible 24 hours daily. Winter transforms the landscape with snow and ice formations but demands careful attention to weather forecasts and road conditions. The Icelandic Road Administration's road.is website provides essential real-time updates.

Budget approximately ISK 25,000-35,000 (£150-215) per day including vehicle rental, fuel, and basic meals. Accommodation ranges from budget guesthouses (ISK 15,000) to luxury hotels (ISK 45,000+) per night.

The South Coast drive delivers Iceland's greatest hits in a single journey, each stop revealing new facets of the island's extraordinary geological story written in ice, fire, and time itself.
