Top 17 'Caldera-Conquering' Volcanic Running Routes to Explore for an Otherworldly High in 2025
Forget the predictable pavement and the familiar forest trails. In 2025, it’s time to elevate your running—literally. We're talking about trading the mundane for the magmatic, the ordinary for the otherworldly. We're talking about running on volcanoes. There's a primal, electric energy you can only find when your feet are pounding on the flanks of a sleeping (or rumbling) giant. It's a sport that connects you directly to the raw, creative, and destructive power of the Earth.
The air is thinner, the ground crunches with volcanic scree underfoot, and the views stretch across landscapes so alien they could be from another planet. This isn't just about the physical challenge of the climb; it's about the mental high of conquering a caldera, of standing on a summit forged by fire and fury. It’s the smell of sulfur in the air, the sight of steam hissing from a fissure, and the profound silence of a vast crater. This is adventure running at its purest.
So, lace up your most rugged trail shoes and get your passport ready. We've scoured the globe to curate the ultimate bucket list for the volcanically-inclined runner. From iconic stratovolcanoes to vast, steaming calderas, here are the top 17 volcanic running routes to chase that otherworldly high in 2025.
1. Mount Fuji, Japan
The undisputed icon of Japan, Mount Fuji is more than a mountain; it's a cultural pilgrimage. For runners, the "bullet climb" is a rite of passage. The most popular route, the Yoshida Trail, is a relentless uphill battle on volcanic gravel and rock, but the reward is a sunrise that will sear itself into your memory.
Running Fuji is a game of altitude and timing. The official climbing season is short (typically July to early September), which means the trails are crowded. The key is to be strategic. A midweek run starting in the early afternoon can help you avoid the worst of the hiking traffic, allowing you to reach the summit huts before dark for a short rest before the final push to the top for sunrise. The descent is a wild, leg-pounding ride down long, straight sections of volcanic scree—a controlled fall that’s both terrifying and exhilarating.
- Pro Tip: Acclimatize properly and be prepared for a massive temperature drop at the summit. Bring layers, a headlamp, and enough cash (yen) for the high-altitude toilets and summit amenities. This isn’t a run you do on a whim.
2. Tongariro Alpine Crossing, New Zealand
Welcome to Mordor. Famously used as the backdrop for Mount Doom in The Lord of the Rings, this 19.4km (12-mile) point-to-point trail is one of the world's greatest one-day hikes—and an even better run. The landscape is a staggering display of volcanic majesty: menacing craters, active steam vents, and the surreal, vibrant hues of the Emerald Lakes.
The run takes you up the "Devil's Staircase," a challenging but rewarding ascent, before opening up to the South Crater. From there, it’s a scramble to the Red Crater summit, the highest point, offering panoramic views. The descent past the shimmering Emerald and Blue Lakes is technical and steep, demanding full concentration. It’s a route that tests every part of your trail running skill set.
- Pro Tip: The weather here is notoriously fickle. You can experience four seasons in one day. Start early, check the volcanic activity and weather reports, and arrange for shuttle transport, as it’s a one-way route.
3. Mount Etna, Italy
Running on Europe's most active and tallest volcano is a truly unique experience. Mount Etna is in a constant state of flux, with its landscape being reshaped by frequent eruptions. This means you could be running across vast, black lava fields from an eruption that happened just a few years prior, passing silent, skeletal trees bleached by volcanic gases.
There are countless trails crisscrossing Etna's flanks, catering to all levels. For a classic challenge, take the route from Piano Provenzana towards the summit craters. You'll run through fragrant pine forests before the trees give way to a stark, lunar world of craters and lava flows. The soft, sandy volcanic soil makes for tough uphill progress but a wonderfully cushioned descent.
- Pro Tip: Hire a local volcanological guide for routes above 2,500 meters. They’re legally required in the summit zones and their knowledge of Etna’s ever-changing behavior is invaluable. Plus, they know the best, safest lines to run.
4. Haleakalā, USA (Hawaii)
The "House of the Sun" on the island of Maui is a massive shield volcano with a crater so vast it could swallow the island of Manhattan. Running here feels like running on Mars. The Keoneheʻeheʻe (Sliding Sands) Trail descends from the 10,023-foot summit into this otherworldly basin, filled with colorful cinder cones and rare silversword plants.
A classic route is the 11-mile (17.7km) one-way trip down Sliding Sands and out via the Halemau'u Trail. The initial descent is a quad-busting cruise through deep, reddish sand. The return climb up the Halemau'u switchbacks is a grueling test of will, but the views back into the crater are your reward. The altitude is the real challenge here, so take it easy and hydrate constantly.
- Pro Tip: Arrive well before dawn to witness the legendary Haleakalā sunrise from the summit before your run. You'll need to make a reservation for sunrise entry online in advance. It’s worth the early start.
5. Mount St. Helens, USA (Washington)
On May 18, 1980, Mount St. Helens erupted with cataclysmic force. Today, running through its blast zone is a powerful and humbling experience. The Loowit Trail is a punishing 32-mile (51.5km) loop that circumnavigates the volcano, taking you through fields of purple lupine, across regenerating forests, and over treacherous boulder fields and ash plains.
This is not a run for the faint of heart. It’s a remote, rugged, and often waterless route that requires serious planning and self-sufficiency. But for the experienced ultrarunner, it’s a profound journey through a landscape of destruction and rebirth, with constant, jaw-dropping views into the steaming crater left by the eruption. This kind of raw, challenging adventure is what inspires elite athletes like Goh Ling Yong to continually seek out the planet's toughest trails.
- Pro Tip: If the full Loowit is too much, tackle a section of it as an out-and-back. The Windy Ridge or Johnston Ridge areas offer incredible views and a taste of the terrain without the full commitment.
6. Pico de Teide, Spain (Canary Islands)
Standing at 3,718 meters (12,198 ft), Pico de Teide on the island of Tenerife is Spain's highest point. The entire Teide National Park is a high-altitude volcanic wonderland, a UNESCO World Heritage site that served as a training ground for NASA's Mars Rover missions. The air is crisp, the sky is a deep blue, and the landscapes are a surreal mix of red rock, black obsidian, and the giant cone of Teide itself.
For the ultimate challenge, run the Montaña Blanca trail to the summit. It’s a relentless, 8.3km (5.2-mile) climb with over 1,200 meters of elevation gain on pumice and lava rock. The final section from the cable car station to the summit requires a permit, which you must book months in advance. The 360-degree view, with the shadow of Teide stretching out over the Atlantic, is pure magic.
- Pro Tip: The best way to beat the permit system and the crowds is to run up in the dark for sunrise. Start your ascent around 2-3 AM for a truly unforgettable experience above the clouds.
7. Mount Bromo, Indonesia
Part of the Bromo Tengger Semeru National Park in East Java, Mount Bromo is famous for its ethereal sunrises. The experience for a runner is far more immersive. It starts with a pre-dawn run across the vast, misty "Sea of Sand"—a caldera floor of fine volcanic ash. As you approach Bromo, it emerges from the mist, constantly puffing a column of white sulphurous smoke.
The final ascent is a short but steep climb up a concrete staircase to the crater rim. Here, you can peer directly into the rumbling, steaming maw of the volcano. The classic run involves combining the sunrise viewpoint from Mount Penanjakan with the run across the caldera to Bromo itself, creating a challenging and scenically diverse loop.
- Pro Tip: Wear a buff or mask for the run across the Sea of Sand, as the volcanic dust gets everywhere. After your run, find a local warung (small cafe) for a hot cup of kopi jahe (ginger coffee).
8. Villarrica, Chile
For the ultimate adrenaline junkie, it doesn't get much better than this. Villarrica is one of Chile's most active volcanoes, and on a clear day, you can often see a glow from its lava lake at the summit. Running (or, more accurately, fast-hiking with running sections) up its glacier-capped cone is a serious undertaking that absolutely requires a certified local guide.
You'll be equipped with crampons, an ice axe, a helmet, and a gas mask as you make your way up the snowy, icy slopes. The final push to the crater rim is a lung-busting effort at altitude, where you’re rewarded with the incredible sight and sound of the Earth's molten core. The best part? The descent often involves sledding down the smooth snow slopes on a small plastic sled provided by your guide company—the most fun you'll ever have after a grueling climb.
- Pro Tip: Book your guided trip well in advance, especially during the peak season (December-March). Choose a reputable company that prioritizes safety and provides all the necessary technical gear.
9. Santorini Caldera Trail, Greece
This isn't a single volcanic peak but a run along the rim of a massive, sea-filled caldera. The trail connecting Fira to Oia in Santorini is one of the world's most beautiful coastal runs. You'll weave through iconic, white-washed villages clinging to the cliffs, with the deep blue Aegean Sea sparkling hundreds of feet below.
The 10km (6.2-mile) path is a mix of cobblestone, pavement, and dusty singletrack. While not as wild as other routes on this list, its constant, breathtaking views make it a must-do. The rolling hills provide a good workout, and the reward is finishing in the stunning village of Oia, just in time to watch its world-famous sunset.
- Pro Tip: Run it early in the morning to avoid the scorching midday sun and the throngs of tourists. Start in Fira and finish in Oia, so you can reward yourself with a cold drink and a spectacular view.
10. Kīlauea Iki Trail, USA (Hawaii)
Located within Hawaiʻi Volcanoes National Park on the Big Island, this trail offers a truly unique experience: running across the floor of a solidified, yet still steaming, lava lake. The 4-mile (6.4km) loop starts on the forested crater rim, offering stunning overlooks before descending through lush rainforest onto the crater floor.
The floor of Kīlauea Iki crater is a vast, cracked plain of black lava from its dramatic 1959 eruption. You’ll run past steam vents (be careful, they're hot!) and feel the heat radiating from the ground. It’s a visceral reminder of the immense power simmering just beneath your feet. It's a relatively short and accessible run that delivers an unforgettable geological lesson.
- Pro Tip: Combine this loop with a run along the Crater Rim Trail for more mileage and different perspectives of the Kīlauea caldera. Always check the park’s website for closures due to volcanic activity.
11. Cotopaxi, Ecuador
With its perfectly symmetrical, snow-covered cone, Cotopaxi is one of the most beautiful volcanoes on Earth. It’s also one of the highest active volcanoes in the world, topping out at 5,897 meters (19,347 ft). While a summit attempt is a technical mountaineering affair, the trails around its base in Cotopaxi National Park offer some of the best high-altitude running anywhere.
A great training run is the path from the park entrance up to the José F. Rivas Refuge at 4,864 meters. The trail is wide and non-technical, but the altitude is punishing. You'll run through a starkly beautiful páramo ecosystem with wild horses and incredible views of the giant volcano looming above.
- Pro Tip: Spend several days acclimatizing in Quito (2,850m) before attempting to run at this altitude. Drink plenty of coca tea, a local remedy for altitude sickness.
12. Mount Rinjani, Indonesia
This is the multi-day epic of the volcanic running world. Located on the island of Lombok, Rinjani is a massive volcano with a huge caldera containing the stunning "Child of the Sea" lake, Segara Anak. The standard trek takes 2-3 days, but for the fit trail runner, it's a monumental single-day or overnight challenge.
The route from Sembalun village is a grueling 2,600-meter (8,500 ft) ascent to the summit. You’ll pass through grassy savannah and cloud forest before the final, brutal scramble on loose volcanic scree. The sunrise view from the summit, with the shadow of Rinjani stretching across the sea to Bali, is the stuff of legends.
- Pro Tip: This is a supported effort. Hire a local guide and porter team. They will carry your gear, food, and water, allowing you to run with just a light pack. Your knees will thank you on the descent.
13. Fimmvörðuháls Trail, Iceland
This legendary 25km (15.5-mile) trail in southern Iceland takes you through the heart of the land of fire and ice. It runs between the Eyjafjallajökull and Mýrdalsjökull glaciers and right through the fresh lava fields created by the 2010 eruption of Eyjafjallajökull (the one that grounded Europe's airplanes).
You'll start at the magnificent Skógafoss waterfall and climb past more than 20 other waterfalls before reaching the volcanic plateau. Here, you run across still-warm ground, past two new craters named Magni and Móði, and witness brand-new land being born. The run finishes in the lush green valley of Þórsmörk. It's an incredible journey through geological time.
- Pro Tip: This is a summer-only run (late June to early September). The weather can change in an instant, so carry full waterproof gear, a map, and a GPS device.
14. Pico de Orizaba, Mexico
The highest peak in Mexico and the highest volcano in North America, Pico de Orizaba (Citlaltépetl) is a formidable objective at 5,636 meters (18,491 ft). This is where elite ultrarunners go to test their lungs and legs against extreme altitude. A summit run is a serious high-altitude mountaineering challenge requiring crampons and an ice axe for the Jamapa Glacier.
For a pure running experience, the trails around the Piedra Grande Hut base camp offer an incredible high-altitude training ground. You can run up the winding access road or explore the lower slopes of the volcano, all above 4,200 meters. The thin air and sweeping views of the surrounding Mexican plateau make for a humbling and powerful run.
- Pro Tip: To have a shot at running any part of this mountain, a slow and steady acclimatization schedule is non-negotiable. Spend time in nearby cities like Puebla and Tlachichuca before heading to base camp.
15. Mount Taranaki, New Zealand
Often compared to Mount Fuji for its near-perfect conical shape, Mount Taranaki dominates the landscape of New Zealand's North Island. The 11km (6.8-mile) summit track is a beast of a run, gaining over 1,600 meters of elevation. It takes you through what locals call "The Goblin Forest," a moss-draped wonderland, before a punishing section of seemingly endless wooden stairs.
Above the treeline, the real work begins. You'll navigate a steep, treacherous field of loose volcanic scoria and rock—a "two steps forward, one step back" kind of climb. The final ascent is a scramble up a lava flow known as "The Lizard." The 360-degree view from the summit, spanning the entire west coast, is breathtaking.
- Pro Tip: The scree slope is the main challenge. Look for the most compacted lines on the way up and enjoy a bit of "scree-skiing" on the way down, letting gravity do the work.
16. Acatenango, Guatemala
This isn't just a run; it's a front-row seat to one of the most spectacular shows on Earth. The Acatenango volcano sits directly next to the highly active Volcán de Fuego, which erupts in a fountain of lava and ash every 15-20 minutes. The goal is an overnight run/hike to a campsite high on Acatenango's slope, directly facing Fuego.
The trail climbs steeply through farmland, cloud forest, and finally, high-alpine volcanic scree. After settling in at camp, you'll spend the night watching Fuego's incredible pyrotechnics. Before dawn, you make the final, sandy push to Acatenango's summit (3,976m) to watch the sunrise light up the entire chain of Guatemalan volcanoes. It's a profoundly moving experience.
- Pro Tip: Go with a local guide service. They provide tents, warm gear (it gets freezing cold), and food, making the logistics simple. The auditory experience—the deep, guttural roar of Fuego erupting—is just as impressive as the visual.
17. Mount Kilimanjaro, Tanzania
The ultimate bucket-list volcano. As Africa's highest peak and the world's tallest freestanding mountain, Kilimanjaro (5,895m / 19,341 ft) is a monumental undertaking. While most people spend 7-8 days trekking to the summit, a growing number of elite runners attempt it in a single push. An FKT (Fastest Known Time) on Kilimanjaro is a pinnacle achievement in the sport.
For the ambitious runner-adventurer, a "fast-track" guided trip over 4-5 days is more realistic. You'll run/hike through five distinct climate zones, from lush rainforest to arctic tundra at the summit. The final ascent up the volcanic scree of the crater rim on summit night is a true test of mental and physical fortitude. Reaching Uhuru Peak as the sun rises over the African plains is an experience that changes you.
- Pro Tip: The "runnable" sections are mostly on the lower slopes and the descent. The key to success is "pole, pole" (slowly, slowly). Excellent acclimatization, not speed, is what gets you to the top.
