The sound arrives before the sight. Walking along the unmarked path that descends towards Gjáin, in the valley of Þjórsárdalur, one perceives a growing buzz that transforms into a chorus of falling waters even before spotting the first waterfall. Then the ground opens up and the landscape changes radically: an emerald volcanic canyon, carved by solidified lava millennia ago, where dozens of small waterfalls plunge into pools of moss and black stone.
Gjáin is located in the Icelandic interior, about 130 kilometers east of Reykjavík, accessible by taking the F26 road that crosses the valley of the Þjórsá river, the longest in Iceland at 230 kilometers. Compared to the island's famous waterfalls — Skógafoss, Seljalandsfoss, Gullfoss — this canyon remains almost unknown to mass tourism, yet it concentrates in a relatively small space a density of waterfalls and lava formations that is hard to find elsewhere in the country.
A landscape sculpted by lava
The geology of Gjáin tells millions of years of volcanic activity. The walls of the canyon are formed by basalt flows that time and water have patiently eroded, creating niches, natural arches, and pools where water collects before continuing its descent. Icelandic moss — among the most lush in the world due to the constant humidity — covers every available surface, transforming the canyon into a gallery of intense green that contrasts with the black of the underlying volcanic rock.
The waterfalls themselves are not monumental in terms of height: many drop for a few meters, some for about ten. But their strength lies in the quantity and arrangement: they fall from every direction, multiply after rains, create a light mist that suspends droplets in the air and transforms sunlight into small ephemeral rainbows. In summer, with the sun in Iceland never fully setting, these optical effects last for hours.
The path to the canyon
There is no official signage to reach Gjáin, and this is an integral part of the experience. The most common starting point is near Háifoss, another waterfall in the area, from where an unmarked path descends towards the canyon. The journey takes about 30-45 minutes on foot in each direction, but the terrain can be slippery and uneven, especially near the water pools.
The bottom of the canyon is narrow in some places and requires caution when moving between the wet rocks. There are no fences, walkways, or tourist structures of any kind: you walk directly on the lava, you leap over small streams, you approach the waterfalls as much as you want. This absence of infrastructure is what makes Gjáin authentic, but it also requires proper equipment.
When to visit and how to organize
The best season to visit Gjáin is between June and September, when the F26 road is passable. This is a dirt road for off-road vehicles: a vehicle with all-wheel drive and good ground clearance is essential, as some sections require fording small streams. Taking a regular vehicle on these roads is illegal in Iceland and can cause serious damage to both the vehicle and the terrain.
There is no entrance ticket to access the area. The most important practical advice is to visit in the early morning hours, preferably before 9, when the light is softer and the number of visitors is minimal. Wearing waterproof shoes with non-slip soles is essential: the wet moss on the lava is treacherous. Allow at least two hours of total time to explore the canyon calmly, without rushing.
The Silence Among the Waterfalls
What remains etched after visiting Gjáin is not a single imposing waterfall but an overall feeling: that of being inside something, not in front of something. The canyon envelops those who traverse it, the moss-covered basalt walls close in, the sound of water becomes omnidirectional, and the fine mist settles on clothes and skin.
In a country where tourism is focused on a circuit of well-defined attractions, Gjáin still represents a margin of genuine discovery. Not because it is secret — it appears in specialized guides and many photographic itineraries — but because its limited accessibility and the absence of facilities keep it in a state of relative integrity. Those who make it here, after kilometers of dirt roads and a walk on uneven terrain, find a landscape that does not need to be interpreted: it speaks for itself, through the incessant sound of water.
