For a unique underwater adventure, dive into the crystal-clear waters of the Silfra fissure , where the North American and Eurasian tectonic plates meet. This experience is truly one-of-a-kind — nowhere else in the world offers it. The site is UNESCO-listed and globally recognised as one of the most stunning dive spots. If you don’t hold the required certifications (Level 1), you can still opt for snorkelling (the more popular option) with a snorkel mask. The water is so clear you’ll enjoy visibility of over 100 m — you’ll see the fissure perfectly.

Iceland is one of the best regions in the world for cetacean observation. Husavik, way up north, is famed for its whale watching. Excursions at sea offer the chance to see various whale species, dolphins and even orcas. If northern Iceland isn’t on your itinerary, tours are also possible from Reykjavik.

Iceland, known for its clear skies, offers a unique opportunity to observe the Northern Lights. They are visible between late August and late March when conditions align: a clear sky, darkness, no light pollution and strong solar activity. Sometimes they can even be seen from within the city. Check out our dedicated guide on how to see the Northern Lights in Iceland for the best chance.

Hot baths in Iceland are deeply rooted in local tradition. Even before modern facilities became popular, Icelanders bathed in natural hot springs to relax and revitalise. This tradition continues—wherever you are in Iceland, you’ll find a hot spring nearby. The most renowned are the Blue Lagoon , Sky Lagoon and the

Secret Lagoon

.

Ice caves formed by seasonal melting create cavities sculpted by water and glacier movement. The dynamic process gives rise to interior spaces where daylight filters through ice, creating ethereal shades of blue and white.

The ice cave experience is seasonal, depending on weather and surface melt. The optimal period is generally November to March, when the cavities are most stable and winter light adds magic. Note: the Katla cave is accessible all year round.

Several glacial regions including Vatnajökull, Langjökull and Mýrdalsjökull host these wonders, each offering a unique experience. For more, see our guide on ice caves in Iceland .

Guided excursions allow visitors to walk on ice and admire glacial formations. Guides will explain how these ice giants formed and their role in Iceland’s ecosystem.

If you can choose, we recommend exploring the Vatnajökull Glacier (Europe’s largest). If you’re in good physical shape, opt for a 5-hour tour for full experience. A 3-hour tour is perfectly fine for beginners — no previous glacier-walking experience necessary.

Horse-riding excursions in Iceland let you explore varied landscapes—from green valleys to desert plains to black-sand beaches. Routes often traverse remote and pristine areas, offering an intimate connection with Icelandic nature.

Icelandic horses are calm and intelligent, making them accessible even for beginners.

Horse-riding in Iceland is also a deep dive into local culture. Guides share stories and traditions of Icelandic equestrian life.

Iceland’s lava tunnels result from volcanic eruptions projecting molten lava across the surface. As the outer layer cooled, the inner lava continued to flow, forming subterranean passages. These tunnels are silent witnesses to Iceland’s geological history.

Your headlamps illuminate frozen lava formations, creating an other-worldly atmosphere. Experienced guides will lead you through underground labyrinths and share insights about the tunnels’ formation and associated geological phenomena.

Dog-sled excursions in Iceland are for all levels. Experienced guides provide full instructions so you can confidently steer your own dog-team.

The activity is highly sought after — we recommend booking well in advance.

If there’s no snow, the tour may be operated using wheeled sleds instead.

These iconic birds, with their slender beaks and sharp eyes, nest on steep cliffs especially along the south-coast (Dyrhólaey) and west-coast (Latrabjarg). These locations offer spectacular panoramas where the puffins move with surprising agility.

The best time to observe them is April to August. During the other months, the puffins are out at sea.

You can also spot them from Reykjavik via an excursion at sea to nearby islands.
