About Glymur

Glymur (pronounced “GLY‑mur”) means “the roar” in Icelandic, a fitting name for a waterfall that can be heard echoing through the surrounding valley long before you see it. With a height of 198 m (650 ft), Glymur is Iceland’s second‑tallest waterfall, rivaled only by the iconic Dettifoss‑area cascades in the north.

Located at coordinates 64.390806, ‑21.251465, the waterfall plunges into a deep, glacially carved canyon that is lined with ancient lava fields, vibrant mosses, and towering basalt cliffs. While the exact altitude of the cascade’s rim is not documented, the surrounding terrain sits at roughly 250 m above sea level, giving the waterfall a dramatic vertical drop that feels almost cinematic.

Glymur’s history is intertwined with local folklore and the early settlement of the South Iceland region. The waterfall was once a vital source of fresh water for nearby farms, and its misty spray was believed to protect the land from harsh winds. Today, it is a beloved waypoint for hikers, photographers, and anyone seeking a taste of Iceland’s untamed wilderness.

How to Get There

By Car

The most flexible way to reach Glymur is to rent a car in Reykjavík and drive ≈ 45 km (28 mi) south along Route 1 (the Ring Road) toward Hveragerði. From the town center, follow the signs for Glymur Trailhead (sometimes marked as “Glymurdalur”). The drive takes about 45 minutes, and you’ll pass through rolling farmlands, geothermal steam vents, and the iconic Hveragerði Geothermal Park—a perfect warm‑up stop before the hike.

By Public Transport

If you prefer public transport, take the Strætó bus from Reykjavík’s BSÍ terminal to Hveragerði (bus line 15). Once in town, a local taxi or a short ride‑share can drop you at the trailhead. Note that the final stretch to the waterfall is not serviced by regular buses, so a private vehicle or organized tour is recommended.

Trailhead Details

• Parking: A modest lot near the river Øxará (Øxará River) provides free parking for hikers. Arrive early in peak summer months to secure a spot.
• Coordinates: 64.390806, ‑21.251465 – plug these into your GPS for pinpoint accuracy.

Best Time to Visit

Season	Conditions	Why Visit
Late Spring (May–June)	Snow melt raises river flow; trails may be muddy but spectacular.	The waterfall is at its fullest, and the surrounding flora bursts into vivid greens.
Summer (July–August)	Stable weather, long daylight (up to 24 hrs).	Ideal for hiking; the canyon walls are dry, and the trail is fully accessible.
Early Autumn (September)	Cooler temperatures, occasional golden foliage.	Fewer crowds and a chance to capture the waterfall against a backdrop of autumn colors.
Winter (December–February)	Ice and snow can make the trail hazardous; some sections may be closed.	For the adventurous, a frozen Glymur offers a surreal, otherworldly view—only with proper gear and a guide.

Pro tip: The best combination of safety, visibility, and water volume is typically late June through early August. Check the Icelandic Met Office (vedur.is) for up‑to‑date weather and river conditions before heading out.

What to Expect

The Hike

The Glymur trail is a moderately challenging loop of roughly 5 km (3 mi) that takes 3–4 hours round‑trip for most hikers. The path winds through a lush river valley, crosses the Øxará on a sturdy footbridge, and climbs a series of switchbacks that lead you into the canyon itself.

• River Crossing: The first bridge spans a swift, icy‑cold river. A sturdy railing ensures safety, but keep a firm grip, especially after rain.
• Canyon Walk: As you descend into the gorge, the canyon walls close in, creating a tunnel of basalt and moss. The roar of the waterfall grows louder with each step.
• Viewpoint: The final outlook offers a breathtaking panorama of the 198‑meter drop, with water crashing into a pool of turquoise‑green rock. On clear days, you can see the distant Þingvellir rift valley.

Physical Demands

• Elevation gain: Approx. 200 m (650 ft).
• Terrain: Rocky, uneven, occasional steep sections. Good ankle support and waterproof hiking boots are essential.

Wildlife & Flora

Expect to see Arctic foxes, ptarmigan, and a variety of lichens and mosses that carpet the canyon floor. The area is a living laboratory for Icelandic geology, showcasing volcanic basalt layers and glacial erosion.

Travel Tips

1. Dress in Layers – Icelandic weather changes in minutes. A moisture‑wicking base, insulated mid‑layer, and waterproof outer shell will keep you comfortable.
2. Footwear Matters – Sturdy, waterproof hiking boots with good traction are a must. The river crossing can be slippery, especially after rain.
3. Pack Light, Pack Smart – Bring a 10‑liter daypack with water, high‑energy snacks, a map (or offline GPS), and a small first‑aid kit.
4. Check River Flow – The Øxará can swell dramatically after heavy rain. If the water looks turbulent, wait for it to subside or turn back.
5. Respect the Environment – Stay on marked trails, pack out all trash, and avoid disturbing nesting birds or fragile moss. Iceland’s ecosystems are delicate.
6. Photography Tips – Early morning light (sunrise) creates a soft golden glow on the waterfall, while late afternoon offers dramatic shadows. A polarizing filter helps reduce glare from the water.
7. Safety First – The canyon can be narrow; keep an eye on loose rocks. If you’re hiking in winter, consider hiring a local guide—some sections become icy and hazardous.
8. Local Cuisine – After the hike, treat yourself to a hot bowl of kjötsúpa (Icelandic meat soup) or fresh fish at a café in Hveragerði. The town’s geothermal greenhouse restaurant is a unique spot to refuel.
