Why travel to Iceland remains safe during the volcanic eruption
In recent years, Iceland’s volcanoes have put on quite a show — fissures opening, lava flowing, and fiery displays lighting up the night sky. It may look dramatic, even intimidating, in photos and headlines, but the reality is far calmer and well-managed. Icelanders are no strangers to their island’s volcanic nature; they’ve been living with it for centuries and know exactly how to keep people safe. So while the earth rumbles and glows in certain remote areas, the rest of the country remains as welcoming, breathtaking, and perfectly safe to explore as ever.

Enjoy exciting Iceland during the eruption
Explore the unique ice formations of Vatnajökull, Europe's largest glacier, on a guided walk. This tour offers a direct experience with a constantly changing landscape. You will see deep crevasses, vertical shafts known as moulins, and potentially an ice cave. Your guide will also point out rare features like glacier mice, a type of moss found on the ice. This hike provides an opportunity to witness the immense scale of the glacier and its uniquely carved landscapes up close.
Join a guided glacier hike on Falljökull, an outlet glacier of Vatnajökull National Park. The tour begins at our comfortable meeting point in Hof, located very close to the glacier. Our indoor facility is cozy and offers free parking, which allows you to avoid the parking fees charged at the Skaftafell Visitor Centre. Please arrive 20 minutes before departure to meet your highly qualified English glacier guide. All essential safety gear is provided, including a helmet, crampons, harness, and ice axe.
After a short ride on the "Tröll Bus," you will walk a short distance to the edge of the glacier. Your guide will demonstrate how to use the equipment and how to safely walk on the ice. During the walk, you'll observe how the receding ice has shaped the surrounding landscape, noting visible marks on the bedrock and a lagoon formed by meltwater.
The tour guarantees 1 hour and 30 minutes on the ice, with an additional 10-minute shuttle ride each way. The remaining time is allocated for a safety briefing and a 20-minute walk on a gravel path to the glacier tongue. Your guide will provide information about the glacier's geology and its impact on the Icelandic environment. This tour is designed to be an educational experience, offering a factual look at a natural phenomenon.
This hike is suitable for most individuals with a reasonable fitness level. Participants should wear warm, layered clothing and sturdy footwear.After returning to the meeting point, enjoy a complimentary hot drink (coffee/hot chocolate) and a candy bar.
You will need a car to join this activity. Silfra Fissure is located in the Thingvellir National Park – around 50 minutes away from Reykjavik. If you do not have a car, you can book this tour here with a transfer.
Once you get to the location, it is important to give your snorkeling guide a filled medical form (it is important to read the medical form before booking the tour). Your guide will then give you all the equipment – a thermal undersuit to keep you warm, a dry suit to keep you dry, fins to swim, and other necessary snorkeling equipment.
Once you get warm and ready, your guide will teach you how to snorkel, what to do if you get tired in the water, and other important information.
You can leave all your clothes and other items in our Tröll bags, which are kept securely at all times. You will then start walking towards Silfra with your dry suit on. The walk to Silfra is short, roughly 5 minutes long.

Why Travel with Troll.is is safe
1. Limited, Controlled Activity
Eruptions are small in scale, monitored by GPS, seismic, and air-quality sensors . Lava flows away from infrastructure, and strategic barrier systems deflect flows in vulnerable zones .
2. Proactive Evacuation and Management
Authorities evacuate affected areas and facilities like the Blue Lagoon immediately. Civil protection teams coordinate with tourism operators for organized, calm procedures.
3. No Disruptions to Flights or Travel Routes
Keflavík International Airport and the Ring Road remain operational; flights continue unaffected. Main tourist routes and accommodations stay open: Blue Lagoon reopens swiftly post-evacuation.
4. Tourism Industry Reinforcing Safety
Icelanders embrace the resilient “Þetta reddast” spirit—trusting systems in place and adapting tourism around natural events.
At Troll.is, we understand that a changing Icelandic landscape—with its dramatic lava flows and occasional fissures—can spark both excitement and questions.
Continuous monitoring by experts
Every day, our operations team collaborates closely with the Icelandic Meteorological Office, Civil Protection, and local authorities to track seismic events and volcanic activity. This real-time intelligence ensures all tours are dynamically adjusted and fully informed.
Flexible and adaptive itineraries
Should a volcanic event prompt restricted access, our itineraries pivot instantly. We have backup routes ready—so while a visit to Blue Lagoon might be temporarily postponed, you’ll still enjoy spectacular alternatives like the Golden Circle, glacier hikes, snorkelling and so much more.
Size matters: small groups, big care
With small group sizes, our guides provide personal attention, quick communication, and efficient logistics.
Proven track record
Time and again, during fissure eruptions between 2021 and 2025 Troll.is operated safely and uninterrupted. Our rich and exciting tours have never been so rewarding, maintaining 5-star reviews and happy explorers.
Why is Iceland so volcanic?
Iceland is one of the most volcanically active places on Earth because it sits at a very special geological crossroads: the Mid-Atlantic Ridge and a mantle hotspot. Here, the North American and Eurasian tectonic plates slowly drift apart, and magma from deep inside the Earth rises to fill the gap, creating new crust. Iceland happens to be the rare spot where this ocean ridge rises above sea level — so the volcanic activity is easy to see. On top of that, Iceland lies over a hot, upwelling area in the mantle — a hotspot — which adds even more heat and magma, making eruptions more frequent and dramatic.
Since Iceland is geologically “young,” its crust is still thin and forming, which allows magma to break through to the surface easily. The result is a stunning landscape of lava fields, geysers, craters, black sand beaches, and glaciers covering volcanoes — a place where fire and ice truly meet.
Iceland is the Earth’s kitchen, bubbling and steaming as it cooks up new land right before your eyes — a magical land of fire and ice.
