What comes to mind when you picture Iceland in summer? Is it thundering waterfalls, black sand beaches, and long scenic drives along spectacular coastlines? You’d be right to think that! And while those experiences are worth every kilometre, they only scratch the surface of what’s possible here during the warmer months.
With nearly endless daylight and more stable conditions, summer opens the door to something deeper. This is the season for getting off the roadside, stepping into the landscape, and discovering the kind of experiences that turn a trip into a real adventure.
If you’re looking beyond the usual stops, we have listed some of our favourite and most rewarding things to do in Iceland in summer, including some of our own Iceland adventure activities.
Why Summer in Iceland is Made for Adventure
Summer in Iceland brings a rare kind of freedom. From late May through to July, daylight stretches well into the night, with the midnight sun offering almost 24 hours to explore. The longest day is on June 21, the summer solstice, with over 21 hours of daylight. But for weeks either side of that date, you can expect around 20 hours of daylight daily. The sun doesn’t set until around midnight and then rises again shortly before 3:00 am, barely dipping below the horizon.
This changes how you travel. There’s no rush to beat the sunset, no need to squeeze everything into a tight schedule. You can take your time, go further, and experience places that feel far removed from the typical tourist route.
Conditions are also more forgiving. Trails are clearer, rivers are more accessible, and highland routes are open. It’s the perfect time to experience the full range of Iceland outdoor activities in summer, from glacier exploration to remote canyon adventures.

Canyoning Under Vatnajökull – Iceland’s Hidden Adventure
If there’s one experience that truly sits beyond the usual tours, it’s canyoning. Hidden beneath the vast ice of Vatnajökull are narrow canyons carved over centuries by glacial meltwater. These are places most travellers never see, let alone explore. Canyoning takes you directly into them.
Instead of viewing landscapes from a distance, you move through them. That might mean scrambling over rocks, wading through clear streams, or descending short drops with the support of a guide. It’s active, immersive, and unlike anything else you’ll do in Iceland.
Our half-day canyoning tour under Vatnajökull is designed to be accessible while still delivering a genuine sense of adventure. With small groups and experienced guides, you’ll explore these hidden environments safely while experiencing the raw power of glacial water shaping the land.
For those looking for something more personal, our private Iceland canyoning experiences allow you to tailor the day to your pace and interests.
Among all the Iceland adventure tours available in summer, canyoning remains one of the least known. For many, it becomes the unexpected highlight of their trip.
Iceland Glacier Hiking and Ice Climbing in Summer
It might come as a surprise, but glaciers are just as accessible in summer as they are in winter.
In fact, for many travellers, summer is the ideal time to step onto the ice. Temperatures are milder, daylight is longer, and conditions often allow for extended exploration across the glacier surface.
Glacier hiking on Vatnajökull gives you the chance to walk across ancient ice, navigating ridges, crevasses, and ever-changing formations. With crampons fitted and a guide leading the way, what might seem like an extreme activity quickly becomes an achievable and deeply rewarding experience.
For those wanting to take it further, ice climbing in Iceland ramps up the adventure and adrenaline. With expert guidance and instruction, even first-time climbers can try ascending natural ice walls, adding another dimension to your stay.
Combined with canyoning, glacier activities offer two very different ways to experience the same landscape: one above the ice, the other shaped by it.
Midnight Sun Hiking in Iceland – A Different Perspective
One of the most unique aspects of summer in Iceland is the midnight sun. Rather than finishing your day in the early evening, you can head out when the light softens and the crowds disappear. Late-night hikes become a completely different experience, with golden light stretching across mountains, glaciers, and valleys.
There’s a calmness to Iceland at these hours that’s hard to find during the day. Trails are quieter, the air feels still, and the landscape takes on a softer, almost unreal quality.
Whether it’s a short walk or a longer hike, exploring under the midnight sun offers a perspective that most visitors never experience. For some initial inspiration for your own adventures, check out our picks for the top 10 hiking trails in Iceland and our Guide to Hiking in Iceland.
Whale Watching in Iceland – Witness Life Out in the Open Ocean
Not all adventures in Iceland happen on land. Summer is the peak season for whale watching, as nutrient-rich waters attract a wide range of marine life to the coast. Tours from popular destinations like Húsavík and Reykjavík offer the chance to see humpback and minke whales, as well as dolphins, in their natural environment.
There’s something quietly powerful about being out on the water, scanning the horizon before a sudden movement breaks the surface. It’s a different kind of adventure, less physical but no less memorable.
For many travellers, it adds balance to a trip filled with hiking and exploration.
Horse Riding in Iceland – Exploring the Traditional Way
Icelandic horses have been part of our country’s culture for over a thousand years, and riding them remains one of the most authentic, enriching ways to explore the landscape.
These horses are known for their calm temperament and unique gait, making them suitable for beginners and experienced riders alike. Guided rides take you across lava fields, along coastal paths, and through wide valleys that feel untouched by time.
It’s a slower way to travel, but no less immersive. Riding through these landscapes offers a sense of connection to Iceland’s history, heritage, and its natural beauty. Looking for a local recommendation? Glacier Horses is also located here in the southeast of Iceland, at the foot of Vatnajökull Glacier.
Snorkelling at Silfra – Explore Between Two Continents
For something completely different, snorkelling at Silfra offers one of the most unusual experiences in Iceland. Located in the Þingvallavatn Lake in the Þingvellir National Park, Silfra sits within a fissure between the North American and Eurasian tectonic plates. The natural rift is filled with glacial water filtered through lava rock over decades. The result is some of the clearest water you’ll find anywhere, with visibility stretching far into the distance.
Floating through this narrow canyon, you’re quite literally moving between continents. The water is cold, even in summer, but dry suits keep you insulated and comfortable throughout the experience.
It’s a calm, almost surreal contrast to the more physical activities, yet still firmly among the most unique Iceland outdoor activities in summer. National Geographic even included this experience in its list of Ultimate Iceland Adventures.
