Three hikers died on Indonesia's Mount Dukono on May 8, 2026, after climbing a restricted volcano for social media content. They ignored a climbing ban. A guide is facing criminal charges. This is the guide those hikers should have read — how to check if a volcano is safe, the alert systems that exist to protect you, the 10 best volcano hikes in the world, and what to do if things go wrong.

What Happened on Mount Dukono — and What Went Wrong
On May 8, 2026, twenty hikers — nine foreigners and eleven Indonesians — were climbing Mount Dukono on Halmahera Island, Indonesia, when the volcano erupted, sending a 10 km ash column into the sky. Three people were killed: two Singaporean nationals (Timothy Heng Wen Qiang, 30, and Shahin Muhrez Abdul Hamid, 27) and one Indonesian citizen (Angel Krishela Pradita, 28). Ten others suffered burns. The remaining 17 were evacuated by nightfall.
Here's what went wrong: Dukono had been at Alert Level II since late March, with a 4 km exclusion zone around the crater enforced since April 17. The Indonesian government's Center for Volcanology (PVMBG) had explicitly banned climbing. The hikers went anyway — police said they were "driven by the desire to create online content." The trip was organized by a Singaporean travel company called The Outside and marketed as "beginner-friendly."
The guide, Reza Selang, claimed he didn't know about the climbing ban. He's now facing criminal charges. Dukono has been erupting continuously since 1933 — 93 years straight. It's one of Indonesia's most active volcanoes. Calling it "beginner-friendly" was reckless.
The One Rule That Would Have Saved Three Lives
Never enter a volcanic exclusion zone. Ever. For any reason. Exclusion zones aren't bureaucratic caution — they're drawn by volcanologists based on eruption modeling, blast radius data, and pyroclastic flow simulations. The zone exists because that's where people die. No photo, no social media post, no "once in a lifetime experience" is worth your life.
Volcanic Alert Level Systems: Check THIS Before You Hike
Every major volcanic country has a monitoring agency and an alert level system. Before hiking any volcano, check its current status. This takes 60 seconds. Here are the systems that matter:
Country
Alert Levels
When Is Hiking OK?
United States (USGS)
NORMAL → ADVISORY → WATCH → WARNING
NORMAL or ADVISORY (with caution)
Covers all US volcanoes including Hawaii, Alaska, Cascades. Check volcano.usgs.gov before any hike.
Indonesia (PVMBG)
I (Normal) → II (Advisory) → III (Watch) → IV (Warning)
Level I only — higher levels have exclusion zones
130+ active volcanoes. Exclusion zone sizes vary. Dukono was Level II with a 4 km zone when 3 hikers died.
Level 1 for most volcanoes. Some restrict at Level 2.
111 active volcanoes including Mt. Fuji. Trail closures enforced strictly.
Italy (INGV)
Green → Yellow → Orange → Red
Green or Yellow (Etna, Stromboli). Guides required above certain elevations.
Etna requires certified guides above 2,920m. Stromboli summit trail reopens/closes based on activity.
Iceland (IMO)
Green → Yellow → Orange → Red (Aviation Color Code) + hazard zones
Depends on specific hazard assessment. Eruption areas often accessible with guides.
Reykjanes eruptions attracted 300,000+ visitors. Check en.vedur.is for current status.
Bookmark these sites. Check them the morning of your hike, not the day before — volcanic conditions change fast. If a volcano's status has elevated since you last checked, don't go. Rebook. The volcano will still be there next week.
The 10 Best Volcano Hikes in the World
I've ranked these based on three criteria: (1) quality of the volcanic experience — can you see craters, lava, eruptions? (2) Accessibility — can a fit intermediate hiker do it? (3) Safety infrastructure — monitoring, guides, trail maintenance. Every hike on this list is on a volcano with a functioning monitoring system.
Europe's most active volcano and the most accessible high-altitude volcano hike in the world. You can take a cable car to 2,500m, then a 4x4 vehicle to 2,920m. From there, a certified guide leads you across lunar lava fields to the summit craters. The views of Sicily and the Aeolian Islands are unreal. I rank this #1 because the infrastructure makes it accessible even for intermediate hikers.
Often called the world's best day hike. You walk across an active volcanic landscape past emerald lakes, red craters, and steaming vents. Mount Ngauruhoe (aka Mount Doom from Lord of the Rings) towers above. The alpine crossing doesn't summit any active craters, making it relatively safe even at Alert Level 1.
The beginner-friendly volcano hike. An hour from Antigua, you hike through forest to fresh lava fields where the ground is still warm enough to roast marshmallows. Yes, people actually do that. The hike is steep but short. Guides are essentially mandatory — they know where the stable ground is.
Japan's highest peak and most iconic volcano. The official climbing season is July-September. Over 300,000 people summit annually. The hike is not technically difficult — it's a well-maintained trail — but altitude sickness hits hard above 3,000m. Sunrise from the summit (goraiko) is a near-religious experience.
Not a summit hike — you walk across lava fields and along crater rims. The Kilauea Iki trail drops into a crater that erupted in 1959, crossing a still-warm lava lake. Between eruption episodes, the park is fully open and safe. During episodes, closed areas are clearly marked. The current eruption cycle makes this the best place to see fresh volcanic activity with minimal risk.
The 'Lighthouse of the Mediterranean.' Stromboli erupts every 10-20 minutes — rhythmic explosions of glowing lava that have been going on for at least 2,000 years. The guided night hike to the crater rim is one of the most dramatic volcano experiences on Earth. Trail access fluctuates with activity — sometimes open to 400m, sometimes the full 924m summit.
One of the world's most active volcanoes, on a French island east of Madagascar. The hike descends into the Enclos Fouqué caldera across a moonscape of fresh lava. When erupting, viewing access is managed by the observatory. Réunion's infrastructure is excellent — paved roads, marked trails, experienced guides.
Technically dormant but geologically young. The Sliding Sands trail descends 850m into the enormous crater — 11 km across, looking like another planet. The sunrise from the summit is so popular that reservations are required. Overnight camping in the crater is available and worth the effort.
You hike Acatenango to watch Volcán de Fuego erupt at night. Fuego erupts every 15-20 minutes, shooting lava and ash into the sky — visible from your campsite at 3,600m on Acatenango's shoulder. The hike is brutal (1,500m of elevation gain) and cold at the top. But watching a volcano erupt from your tent is a once-in-a-lifetime experience.
You can't summit Arenal (it's restricted), but the trails around its base pass through old lava flows with views of the textbook-perfect cone. The hot springs in the area are heated by the volcano. Good for families and anyone who wants the volcano experience without the altitude or difficulty.
Essential Volcano Hiking Gear
Volcano hiking isn't regular hiking. The terrain is sharper, the air can be toxic, and the weather changes faster. Here's what you actually need:
Required for Any Volcano Hike
Sturdy boots — lava rock is razor-sharp and will shred trail runners
Sun protection — zero shade on lava fields. Hat, sunscreen, sunglasses.
2+ liters of water — dehydration risk is extreme on hot, shadeless lava
Headlamp — many summit hikes start at 2-4 AM for sunrise
Layers — temperature can drop 20°C between base and summit
Additional for Active Volcanoes
Helmet — ballistic ejecta (flying rocks) are the #1 killer near active craters
Goggles — volcanic ash is pulverized glass that scratches corneas
Long sleeves/pants — protection from hot ash and gas burns
Charged phone — with local emergency numbers and monitoring agency website bookmarked
Emergency whistle — audible through ash clouds when visibility drops to zero
GPS device or offline maps — trails disappear under fresh lava/ash
When NOT to Hike a Volcano
Some situations are non-negotiable. If any of these apply, don't go:
Exclusion zone is active
If the monitoring agency has set an exclusion zone around the crater, that area is off-limits. Period. This is what killed the Dukono hikers.
Alert level has elevated since you last checked
If the status changed from NORMAL to ADVISORY (or any upward change), reassess. The volcano is telling you something.
Solo hiking on an active volcano
If something goes wrong — a gas pocket, a collapse, a sudden eruption — no one will know where you are. Always hike with at least one other person or a guide.
Poor visibility (fog, clouds, darkness without proper gear)
You need to see the terrain. Lava tubes, fumaroles, and unstable crater edges are invisible in fog. Many fatal falls on volcanoes happen in low visibility.
Strong sulfur smell with no wind
Volcanic gases pool in low areas during calm conditions. CO₂ is heavier than air and odorless — it accumulates in depressions and can suffocate without warning. If you smell strong sulfur with no breeze, leave immediately.
What to Do If a Volcano Erupts While You're Hiking
First: don't panic. If you're hiking a properly monitored volcano at a safe distance, you're probably fine. But if eruption activity increases unexpectedly:
Move laterally, not downhill.Pyroclastic flows and lahars travel through valleys and drainages. Get to ridgelines or high ground away from channels.
Cover your mouth and nose. Volcanic ash is pulverized glass and rock. It damages lung tissue. Use your respirator, or a wet cloth as a last resort.
Protect your eyes. Ash falls can reduce visibility to zero and scratch corneas. Goggles or wrap-around sunglasses help.
Don't cross valleys or stream channels. These are lahar pathways. Lahars can arrive with little warning, especially on snow-capped or glacier-covered volcanoes.
Get indoors or under cover if possible. Heavy ashfall can collapse lightweight structures. Sturdy buildings or vehicles offer protection from falling tephra.
Contact emergency services. Use the local emergency number and the monitoring agency hotline. If you have cell service, share your GPS coordinates.
Lava flows are usually survivable — they move slowly enough to walk away from (1-10 km/h on flat ground). Pyroclastic flows are not survivable at close range — they move at 100-700 km/h and reach temperatures of 200-700°C. Only 3 people have ever survived direct contact. Your only defense against pyroclastic flows is not being in their path.
Frequently Asked Questions
Can you hike an active volcano?
Yes — many of the world's most popular hikes are on active volcanoes. Mount Etna, Stromboli, Kilauea, Pacaya, and Tongariro are all active and regularly hiked. The key is checking the alert level before you go. Volcanoes at the lowest alert levels (NORMAL/Green/Level I) with no exclusion zones are generally safe for hiking. Higher alert levels may restrict access to specific zones.
What's the most dangerous volcano to hike?
Any volcano with an active exclusion zone is dangerous — that's the whole point of the zone. Beyond that, volcanoes with short warning times pose the greatest risk. Indonesia's Dukono (3 deaths in May 2026), Merapi (over 350 deaths in 2010), and Guatemala's Fuego (over 400 deaths in 2018) have all killed hikers or nearby residents. The safest volcano hikes are on well-monitored volcanoes in countries with strong alert systems (US, Japan, Italy, New Zealand).
Do you need a guide to hike a volcano?
It depends on the volcano. Some require guides by law: Mount Etna above 2,920m (Italy), Stromboli (Italy), and many Indonesian volcanoes. Others have optional but recommended guides: Pacaya (Guatemala), Piton de la Fournaise (Réunion). US national park volcanoes (Kilauea, Haleakala) have self-guided trails. For any active volcano you haven't hiked before, I'd recommend a guide — they know the terrain, the hazards, and the escape routes.
What should you do if a volcano erupts while hiking?
Move laterally, not downhill. Pyroclastic flows and lahars travel down valleys and drainages. Get to high ground away from valleys and stream channels. Cover your mouth and nose with a cloth or mask — volcanic ash is pulverized glass that damages lungs. If you can see the eruption, you can usually outrun lava flows (they move 1-10 km/h on flat ground). Pyroclastic flows are unsurvivable — they move at 100-700 km/h. Your only defense is distance.
What gear do you need for volcano hiking?
Essential gear: sturdy boots (lava rock is razor-sharp), N95 or P100 respirator (volcanic gases are toxic), headlamp (many hikes start pre-dawn), sun protection (no shade on lava fields), 2+ liters of water, layers for temperature changes (it can be 30°C at the base and 0°C at the summit). For active volcanoes, add: a helmet for falling rock/ejecta, goggles for ash, and a charged phone with emergency contacts for the local monitoring agency.
