Hike overview

The Glymur hike takes you to Iceland's second-highest waterfall, which plunges 196 meters into a narrow, spectacular canyon. The trail runs mainly along the edges of the canyon and offers impressive panoramic views from start to finish. At the beginning of your adventure, you will also discover the Thvottahellir cave.

Located just an hour from Reykjavik, this hike is an excellent half-day excursion for adventure seekers who don't want to stray too far from the capital.

Difficulties of the hike

The well-marked route presents several challenges: the slopes are steep in places, and there are some slightly dizzying passages. You will also have to cross the Botnsá River twice.

The first crossing is at the bottom of the canyon, where you can use a rope on a tree trunk to help you keep your balance. The second crossing, at the top of the waterfall, requires walking through cold water, which is usually knee-deep. The bed of stones is slippery, and the current can be strong.

What you'll love

  • Spectacular views of the waterfall and canyon: Throughout the trail, you will see Glymur from different angles and enjoy impressive views of the narrow canyon.
  • Thvottahellir Cave: At the beginning of your journey, you will cross this spacious natural cave.
  • More reasonable visitor numbers: Unlike iconic waterfalls such as Gullfoss or Skógafoss, Glymur requires more effort, which naturally filters out visitors, allowing you to enjoy a more authentic experience.

Practical information

Best time to go

June to September/October when the tree trunk is in place for the first river crossing and the trail is clear of snow. Since the hike is popular, consider setting off early to enjoy the serenity of the place.

Round-trip option

If you're not up for the second crossing in the cold, just head back the same way. You will already have enjoyed the most spectacular views.
