Few travel experiences feel as powerful as standing somewhere and watching the Earth move beneath you. Lava glowing after dark, volcanic landscapes stretching towards the horizon and enormous plumes rising into the sky have turned volcano tourism into an increasingly popular adventure travel experience.
But volcanoes are not theme park attractions. They are dynamic geological systems that can change quickly, sometimes with little warning. A destination that was open to visitors yesterday can have a new exclusion zone, road closure, ash warning or evacuation order today.
Recent volcanic activity around the world is a reminder of just how important that distinction is. In Indonesia, Krakatau has continued eruptive activity during 2026, with authorities repeatedly maintaining exclusion zones around the active crater. In Iceland, monitoring around the Reykjanes Peninsula continues to track magma accumulation beneath Svartsengi, with authorities warning that a future intrusion or eruption could have a relatively short warning period.
For travellers, the lesson is simple: volcano tourism can be fascinating and rewarding, but it requires preparation, respect for local restrictions and access to reliable, up-to-date information.
Why Volcano Tourism Is Becoming So Popular
Volcanoes offer something that few conventional tourist attractions can replicate: the chance to witness an active geological process.
Destinations such as Iceland, Indonesia, Italy, Japan and Hawaii attract visitors with volcanic landscapes, lava fields, crater lakes, geothermal areas and dramatic mountain scenery. Some travellers hike volcanic trails, while others join guided tours, take helicopter flights or visit viewing areas established a safe distance from active zones.
Social media has also changed the way people discover these destinations. A spectacular photograph of glowing lava or a volcanic plume can turn a previously unfamiliar location into a bucket-list destination almost overnight.
That popularity comes with a responsibility. A dramatic photograph does not show the gas concentrations, unstable ground, wind direction or current hazard level outside the frame.
The safest approach is to treat volcanic areas as living environments rather than ordinary sightseeing locations.
Recent Volcanic Activity: What Travellers Should Know
1. Indonesia: Krakatau and Other Active Volcanoes
Indonesia is one of the world's most volcanically active countries, and its volcanoes are an important part of both the landscape and tourism industry.
In 2026, eruptive activity continued at Krakatau. Reports from the Smithsonian Institution's Global Volcanism Program, based on information from Indonesia's PVMBG, recorded ash emissions and eruptive activity through July and August. During parts of August, ash plumes rose hundreds of metres above the summit, while an exclusion zone was maintained around the active crater.
This does not mean that every destination in the surrounding region is unsafe. It demonstrates why travellers need to distinguish between a volcano being active and a particular area being open or safe for visitors.
Indonesia also has numerous other active volcanoes, including Semeru, Lewotobi and several volcanoes across Java, Bali, Flores and the eastern islands. Conditions and alert levels can change, so travellers should check official Indonesian volcanic hazard information before visiting an active volcano.
Travel takeaway: Never assume that a familiar hiking route is still open simply because it appears on a travel blog or social media post. Check the latest official alert level, exclusion zone and local instructions before setting out.
2. Iceland: Reykjanes Peninsula
Iceland has become one of the world's most recognisable destinations for volcano tourism, particularly around the Reykjanes Peninsula and the area near Grindavík.
The volcanic system remains closely monitored. In an August 2026 update, the Icelandic Meteorological Office reported continued ground uplift and magma accumulation beneath Svartsengi. It stated that the most likely scenario remained a future magma intrusion towards the Sundhnúkur crater row, potentially leading to another eruption. Previous events in the area had provided warning times ranging from approximately 20 minutes to just over four hours.
This is an important lesson for volcano tourists: a quiet-looking landscape does not necessarily mean that volcanic hazards have disappeared.
Iceland's extensive monitoring systems provide valuable information, but monitoring does not remove the underlying risk. Travellers should always follow current closures, road restrictions and safety instructions rather than relying on how calm the volcano looks on the day.
3. Italy: Mount Etna and Stromboli
Italy offers some of Europe's most accessible volcanic experiences. Mount Etna in Sicily and Stromboli in the Aeolian Islands are both active volcanoes with long histories of eruptions and monitoring.
Italy's National Institute of Geophysics and Volcanology, or INGV, provides real-time volcanic information for several active Italian volcanoes, including Etna and Stromboli. Its monitoring system includes seismic data, bulletins and, for some volcanoes, webcam and thermal-camera imagery.
For visitors, this illustrates why official monitoring is so important. Volcanic activity can affect access routes, tours and aviation without necessarily meaning that an entire region is closed.
Travel takeaway: Check the latest local volcano bulletin and tour operator instructions before heading towards an active crater or summit area.
Volcano Risks Go Far Beyond Lava
When people imagine a volcanic eruption, they usually picture flowing lava. Lava is certainly dangerous, but it is only one of the hazards travellers need to understand.
Volcanic Gases
Active volcanoes can release gases including sulphur dioxide and carbon dioxide. Some volcanic gases can be difficult to detect without monitoring equipment, and carbon dioxide can accumulate in low-lying or poorly ventilated areas.
That is one reason visitors should never enter restricted volcanic areas simply because there is no visible lava or ash.
Gas conditions can change with weather, wind and volcanic activity. A location that appears harmless can become hazardous when conditions change.
Volcanic Ash
Volcanic ash is not simply soft dust. It can contain tiny, sharp particles of volcanic rock and glass.
For people on the ground, ash can irritate the eyes and respiratory system. For aviation, airborne volcanic ash is a serious hazard. The International Civil Aviation Organization notes that volcanic ash can be highly abrasive and can create significant risks for aircraft engines and other components.
This is why a volcanic eruption can disrupt flights far beyond the immediate area surrounding the volcano.
Unstable Ground
Volcanic landscapes can be deceptive.
Fresh lava fields, crater edges, geothermal areas and recently formed ground can remain unstable. Surfaces may be thin, fractured or weakened by heat underneath.
Never step beyond an established trail or barrier to get a closer photograph. A few extra metres may not seem significant, but volcanic terrain does not behave like an ordinary hiking trail.
Sudden Changes in Weather and Visibility
Mountain volcanoes can also create challenging weather conditions. Cloud, wind, rain and darkness can dramatically reduce visibility and make navigation more difficult.
If ash begins falling, visibility can deteriorate quickly. Strong winds can also move ash or volcanic gases away from the eruption site.
The Golden Rules of Safe Volcano Travel
1. Never Cross an Official Exclusion Zone
This is the most important rule.
Do not climb over barriers, ignore road closures or follow unofficial trails because you see other people doing it.
Official exclusion zones exist because authorities have access to monitoring data and risk assessments that travellers do not.
Social media posts can also be outdated within hours. A video showing people safely standing near a lava field may have been recorded before conditions changed.
2. Follow Local Authorities, Not Social Media
Before visiting an active volcano, identify the official sources responsible for monitoring and emergency information in that country.
Depending on the destination, this may include a geological or meteorological agency, civil protection authority, police, local government or airport authority.
Save their websites and official social media accounts before you travel.
3. Wear Appropriate Protection
If you are visiting an area where volcanic ash may be present, basic protective equipment can make a significant difference.
- Carry suitable eye protection such as protective goggles.
- Consider an N95 or equivalent particulate mask where ash exposure is possible.
- Wear sturdy closed-toe footwear.
- Carry enough water for the planned activity.
- Take warm or weather-resistant layers for exposed volcanic environments.
Protective equipment does not make an unsafe area safe. If authorities close an area, leave the area rather than relying on protective gear.
4. Choose Experienced Guides
If you want to visit an active volcanic area, consider using a reputable local operator with current knowledge of the area.
Experienced guides can understand local routes, weather conditions, closures and evacuation procedures. They can also help prevent visitors from accidentally entering restricted areas.
For helicopter or other aerial tours, use properly licensed operators and follow all aviation safety requirements.
5. Check Your Travel Insurance
Volcanic eruptions can create expensive travel problems even when you are nowhere near the volcano.
Flights can be delayed or cancelled. Roads can close. Tours can be suspended. Accommodation may become unavailable in affected areas.
Before travelling, check whether your travel insurance covers disruption caused by volcanic eruptions and other natural disasters.
Pay attention to exclusions, evacuation coverage, alternative transport and cancellation conditions. Some policies require specific circumstances before volcanic disruption becomes claimable.
Why Mobile Connectivity Matters During a Volcanic Event
Reliable mobile data is not a substitute for emergency services or official instructions. But during a rapidly changing situation, connectivity can help you receive and act on information faster.
Emergency Alerts
Depending on the country and your device, emergency information may be distributed through government alert systems, SMS, mobile applications or other notification channels.
Having working cellular data gives you another way to access official information when conditions change.
Flight Updates
Volcanic ash can affect aviation well beyond the immediate eruption area. ICAO operates an international volcanic ash information framework that brings together volcano observatories, volcanic ash advisory centres, meteorological authorities and aviation organisations to distribute information relevant to flight operations.
For travellers, this can mean checking airline notifications, airport websites and booking systems when flights are disrupted.
If hundreds or thousands of passengers are affected at the same time, being able to access your airline's app or website without waiting for overloaded airport Wi-Fi can be extremely useful.
Maps and Evacuation Routes
Navigation is another important reason to maintain mobile connectivity.
During a disruption, roads may close and normal routes may change. Live maps can help you understand your surroundings and find alternative routes when official authorities indicate that travel is still safe.
However, always follow official evacuation instructions over whatever route a navigation app suggests.
Communication With Family
If you are travelling alone or with family, being able to send a message can provide reassurance during a disruption.
Before visiting a remote volcanic area, tell someone where you are going and when you expect to return. Do not rely entirely on mobile coverage in remote mountains, however. Download offline maps and keep your phone charged as a backup.
How a Travel eSIM Can Help
A travel eSIM can be a practical part of your connectivity preparation, particularly if you are travelling internationally and do not want to rely entirely on airport Wi-Fi after landing.
With a compatible phone, you can install your travel eSIM before departure and activate or connect it according to the provider's instructions. This means you can have a mobile data option ready when you arrive at your destination.
For travellers visiting volcanic regions, consider a plan based on more than just its price or data allowance.
- Check which local networks the eSIM supports.
- Confirm whether the destination is included in the plan.
- Check whether 4G or 5G access is supported.
- Understand any fair-use or speed restrictions.
- Install the eSIM before travelling where possible.
- Download offline maps before entering remote areas.
- Keep your home SIM available if you need your normal number for calls or messages.
- Carry a power bank for longer excursions.
Travel eSIMs are not emergency communication systems, and coverage can never be guaranteed in every mountain, crater or remote location. A local network may also become congested or unavailable during a major disaster.
Think of your eSIM as one layer of a broader safety plan, alongside official alerts, offline maps, emergency contacts, travel insurance and appropriate preparation.
Before You Visit an Active Volcano: A Simple Checklist
Before leaving your accommodation, take a few minutes to check the following:
- Is the volcano or hiking area officially open?
- What is the current alert level?
- Is there an active exclusion zone?
- Are there any road or trail closures?
- What is the current weather and wind direction?
- Is volcanic ash expected?
- Do you have suitable footwear and eye protection?
- Do you have an appropriate mask if ash is possible?
- Is your phone fully charged?
- Do you have working mobile data?
- Have you downloaded offline maps?
- Does someone know where you are going?
- Do you know how to leave the area if conditions change?
If the answer to any safety-critical question is unclear, pause the trip and get current information before continuing.
Volcano Tourism Should Be About Respect, Not Risk
Volcano tourism offers some of the most memorable experiences in the world. Few landscapes demonstrate the power of nature quite as dramatically as an active volcanic region.
But the most impressive photograph is never worth entering a restricted area or ignoring an evacuation order.
Recent activity at Krakatau demonstrates that volcanic systems can remain active for extended periods, while monitoring around Iceland's Reykjanes Peninsula shows how authorities can continue preparing for possible future eruptions even when conditions appear relatively quiet.
The safest volcano traveller is not the person who gets closest to the lava. It is the person who understands the risks, checks official information, follows local restrictions and is prepared to change their plans when conditions change.
Before your next volcanic adventure, prepare your safety gear, check the latest official alerts, download essential information offline and make sure you have a reliable way to access mobile data.
A travel eSIM from G-Starlink can help keep you connected while travelling overseas, giving you a convenient mobile data option for maps, travel updates and communication. Explore available travel eSIM plans at gstarlink.com.au before your next adventure.
Stay curious, stay prepared and respect the volcano.
