Kerið Crater

Discovering Kerið Crater: Iceland’s Vivid Volcanic Caldera

Carved by volcanic forces about 6,500 years ago, Kerið (often spelled Kerid) is one of Iceland’s most striking volcanic crater lakes. Nestled along the Golden Circle route on the South Iceland Seismic Zone, its steep red-and-black slopes frame a serene sapphire pool—creating a vivid contrast and a photographer’s dream.

Volcanic Origins and Geological Features

Kerið formed during the Grímsnes volcanic period when a magma chamber emptied underground and then collapsed inward, leaving a steep-walled caldera rather than a classic cone. Unlike many basaltic craters in Iceland, Kerið’s rim is composed mainly of fine volcanic ash and tephra, giving its walls their distinctive rust-red color. Seasonal rainfall and snowmelt fill the crater, maintaining a lake depth that varies between 7 and 14 meters depending on precipitation and groundwater levels.

Visitor Experience: Trails and Views

Entrance and Fees
A modest entry fee (around 400 ISK for adults, 200 ISK for children) supports site maintenance. You can purchase tickets on-site with card or cash.

Rim Walk
A well-marked trail circles the crater rim—an easy 15–20 minute loop that offers panoramic views into the crater and across the surrounding lava fields. Benches at key vantage points invite you to pause and admire the lake below.

Water’s Edge
Stone steps descend to the crater floor, allowing you to walk along the water’s edge. From here, you see the crater walls in dramatic relief and can enjoy a quieter perspective away from the rim.

Seasonal Highlights and Photography Tips

Best Light
Visit in early morning or late afternoon when the low sun enhances the reds of the crater walls and casts long shadows—ideal for dramatic shots.

Summer (June–August)
Wildflowers bloom on the rim, adding bursts of yellow and white against the red ash slopes. Midnight sun extends your shooting window well past typical daylight hours.

Autumn (September–October)
Lichen and moss on the slopes take on golden and green hues, contrasting beautifully with the crater’s deep blue water.

Winter (November–March)
A light dusting of snow highlights the crater’s contours, but paths can be icy—use crampons or traction aids for safety.

Photography Gear
A polarizing filter cuts glare on the water and intensifies color contrasts. Wide-angle lenses capture the full expanse of the crater, while telephoto shots isolate patterns in the tephra layers.

Integrating Kerið into the Golden Circle

Kerið sits just off Route 35, about 60 km from Reykjavík. It pairs perfectly with other Golden Circle attractions:

• Þingvellir National Park (50 km west): Rift valleys and historic parliament site.
• Geysir Geothermal Area (30 km east): Strokkur eruptions and steaming vents.
• Gullfoss Waterfall (10 km beyond Geysir): The iconic double-drop falls of the Hvítá River.

Slot Kerið in your itinerary as a tranquil counterpoint to the higher-energy sites, spending 30–45 minutes exploring before moving on.

Practical Information and Tips

• Getting There: No public bus service—self-drive or book a guided Golden Circle tour. Parking is available at the entrance.
• Clothing: Dress in layers with windproof outerwear; crater rims can be chilly even in summer.
• Accessibility: The rim trail is relatively flat but unpaved; not wheelchair- or stroller-friendly.
• Respect the Landscape: Stay on marked paths. The ash slopes are fragile; off-trail walking accelerates erosion.

Final Reflections

Kerið Crater offers a vivid glimpse into Iceland’s volcanic past. Its colorful tephra walls, calm blue lake, and accessible trails make it a gem on the Golden Circle. Whether you’re a geology enthusiast, landscape photographer, or casual traveler, Kerið provides a moment of quiet wonder amid Iceland’s dynamic terrain. Pause here, soak in the colors, and reflect on the fiery forces that shaped this extraordinary landscape.
