Glymur (sounds like “glimmer”; my Icelandic dictionary says it means “clash or ringing”) is said to be the tallest waterfall in Iceland at 196m.

I had read that it was once a very popular attraction as the Ring Road used to go around Hvalfjörður (the Whale Fjord; I think is pronounced “KHVAHL-feeur-thur”) where this waterfall can be found.


Then, the toll tunnel that went under the fjord bypassed the old route and became the new route for the Ring Road.

As a result, we ended up with a bit of an adventure and a quieter (albeit rugged) experience here.

Another cool thing about this hike was that we also got to see a natural arch as a bonus!

Recently with the Eyjafjallajökull eruption in 2010, the consequent melting of part of the glacier resulted in the apparent revealing of a new waterfall that was said to be even taller than Glymur.

However, details on the other waterfall were sketchy as its accessibility was said to be difficult.

In any case, Glymur was said to be the tallest when we visited it in 2007, and as you can see from this page, we have lots to say about it.

Hiking from the trailhead to a junction

Looking back towards Hvalfjörður (the Whale Fjord) fronted by a large field of wildflowers on the trail to Glymur

From the trailhead (see directions below), we followed what appeared to be a fairly obvious dirt trail leading away from the Hvalfjord past a field of blooming purple flowers.

Somewhere along the way, we apparently took a false trail because it took us a little while to figure out where the correct trail continued.

Eventually, we managed to pick up the correct trail as we backtracked, then made sure we followed trail markers (basically rocks spray-painted with yellow dots on them).

This ultimately led us along a dilapidated barbed wire fence.

From that point, we were able to continue following the correct trail (though we really had to concentrate as some parts were easy to go astray).

We eventually got to a point where the trail curved towards a junction roughly a kilometer away from the trailhead.

At this junction, we had a choice of continuing to go straight or taking the path on our right.

Hiking to Glymur along the south side of the canyon

We ultimately chose to take the path on the right, which then led us to what appeared to be a cave.

However, once we descended inside the cave, we saw that there was some brightness on the other end.

That was when we realized that this was really a natural arch. How cool is that?!?!

At the other opening of the “cave,” we saw that there was actually an arch splitting this opening creating a double-arch.

Looking out the other opening of the cave-like tunnel, which revealed a bit of a double arch. This arch was quite an unexpected surprise as it added to the hit list of reasons to enjoy this hike

The size of this arch would probably rival some of the more modest-sized arches in Arches National Park in Utah.

So this landmark made an already scenic and tranquil hike even more alluring!

The trail then descended immediately from the arch towards the level of the river that was responsible for Glymur.

There was a reinforced log spanning the river with a metal wire to hold onto for balance.

Once we were on the other side of the river, we then went up a steep slope with a lot of loose talus.

The climb was steep enough to require us to use our hands a little bit.

We had to be very careful for a slip and fall here could’ve led to some serious injury.

Once we got over the pretty steep climb, the trail became more straightforward to follow.

However, the trail was also narrower (hugging cliffs and dropoffs in some sections) and it was generally uphill for the next kilometer.

Along this stretch, there were some smaller cascades we went around as well as some rockier sections that felt more like scrambles than trail hikes.

In any case, parts of Glymur could be seen in the distance, which further strengthened our resolve to keep going.

Precarious views of Glymur

Eventually, we started reaching some viewpoints by the cliff’s edge of Glymur.

The first few viewpoints only provided partial views of the well-concealed waterfall accompanied by smaller waterfalls in a different part of the gorge.

As we continued going up the trail, we eventually came upon an even better view of the falls (shown at the top of this page).

From that vantage point, we could better appreciate the rough terrain of the narrow gorge that the waterfall was hidden within.

Meanwhile, we could see birds flying back and forth between cliffs before the falls.

As we went higher up the trail, we’d eventually get to a more direct view of Glymur, but the drawback was that we weren’t able to see its bottom.

This was the only overlook where we were able to see the top and bottom of the Glymur waterfall without putting our lives in substantial risk

We ultimately turned around at this point thinking there might not be anything more to see.

However, in hindsight, we probably should’ve gone all the way to the top of the waterfall just to complete the whole experience on this side of the river.

Glymur hiking excursion summary

All in all, we logged about 5km of hiking and it took us about four hours to do the entire hike.

That said, the time we spent included losing the trail at the start as well as some additional scrambling for better views.

We definitely tested our fear of heights and butterflies in our stomachs as each viewpoint of Glymur involved getting close to the sheer dropoffs of the cliffs making up the gorge.

Context of the rugged landscape surrounding the Glymur trail

We were careful not to get too close to the edge since we couldn’t be sure of the stability of the ground we were on.

Finally, it’s worth noting that had we gone up the other path at the trail junction (i.e. we stayed left instead of going right through the natural arch), then we would’ve been up to the top of the waterfall from the opposite side of the gorge.

We can’t say more about this way since we didn’t do it, but we did see other hikers go up that way while we were returning to the trailhead.

Perhaps next time we’re here, we’ll try out that option.


Glymur resides in the Southern Region of Iceland. It is administered by the municipality of Hvalfjarðarsveit. For information or inquiries about the general area as well as current conditions, you may want to try visiting their website.



From Reykjavik CBD, we drove about 9km east to the Ring Road (Route 1) then went north on it for about 24km to a fork right before the tunnel going beneath the Hvalfjörður. We turned right (to avoid the tunnel) and went onto Route 47, which continued alongside the fjord for about another 35km.

Just past a bridge at the head of the fjord, there was a signposted turnoff leading 3km further inland to the Glymur car park and trailhead. This drive took us a little over an hour in each direction.

Glymur December 20, 2008 2:32 am by _Anonymous2 - We visited Glymur last summer, with our two teenage daughters. After a beautiful but challenging hike, we got tired of listening to older daughter's complaining. We saw the falls, but didn't make it to the top of the falls. We're going back this summer, without kids, and WILL make it to the top. Amazing beauty. ...Read More
