Frequently Asked Questions

About Waterfall Tours in Iceland

Iceland is home to hundreds of beautiful waterfalls, all varying shapes and sizes. On Waterfall Tours, which are often combined with other activities, you allow yourself an intimate up-close encounter with these primordial forces of nature.

1. What are the most famous waterfalls in Iceland?

There are countless waterfalls in Iceland. The most famous are Gullfoss (on the Golden Circle), Dettifoss, Glymur, and the picturesque Seljalandsfoss and Skogafoss on the south coast.

2. Why are there so many waterfalls in Iceland?

The North Atlantic climate of the island produces frequent rain and snow. This, along with the melt water produced by glaciers making Iceland extremely suited for waterfalls.

3. Where does the water of Iceland’s waterfalls come from?

Most of Iceland’s water comes from the glaciers, although much also comes from springs and rainfall on the mountains.

4. Can you go rafting or kayaking down any waterfalls in Iceland?

No. You can raft down rapids and rivers in North Iceland, however.

5. Are there any waterfalls in Iceland that have caves behind them that are accessible?

Yes—the most famous waterfall with an accessible cave would be Seljalandsfoss, on the South Coast. Close by is Kvernufoss, which you can also walk behind. Do not attempt to go behind a waterfall in winter, it’s very dangerous as the cliffs and rocks get icy.

6. Why do waterfalls often have rainbows in front of them?

A rainbow is caused by the reflection, refraction and dispersion of light in water droplets. Because of the constant mist of water around waterfalls, the sunlight frequently creates rainbows. One waterfall in Iceland that is very frequently known to display a rainbow is Skogafoss, on the South Coast.

7. What is Iceland’s most powerful waterfall?

Dettifoss in the Northeast has the greatest flow of water, with a width of 100 metres and a drop of 44 metres, making it the most powerful waterfall in Europe.

8. What is Iceland’s tallest waterfall?

Officially, it is the waterfall Glymur in South Iceland. The drop of these falls is over 190 metres, making it twice as tall as Iceland’s second highest waterfall, Skogafoss. Since 2007, a new waterfall, Morsarfoss, became visible after the glacier Morsarjokull started melting. These new falls measure at least 240 metres in height, making them the tallest of all.

9. Is the water in the waterfalls of Iceland drinkable?

Some of them, yes. The ones that have clear, spring water have drinkable water, but the ones that come from glacial rivers and have murky water are not.

10. What happens to the waterfalls in winter, do they freeze?

Below 0 degrees Celsius, water freezes; in the case of a waterfall, it freezing over depends on the power of its flow. Sometimes, the whole waterfall freezes, while at other times, parts of it do while the water still rushes down past chunks of thick ice.
