The Volcanoes Worth Traveling For

But according to Dr Tamie Jovanelly (Dr Jo), geologist, author, and founder of Adventure Geology Tours, the appeal goes far beyond the possibility of seeing an eruption.

What often surprises visitors, she reveals, is the extent to which volcanoes have shaped human history. "Once you learn about how important they are in the rebuilding of the Earth, and how they can change landscape and civilization, people become very interested in that," she explains. "You're in Italy, in the Mount Vesuvius area, drinking beautiful wine from vineyards that have been around for hundreds of years. That's the result of volcanic activity producing these beautiful volcanic soils that feed the grapes."

The same is true in destinations where the volcanic origins are less obvious. Dr Jo points to Santorini, where millions of travelers arrive each year for the whitewashed villages and bright orange sunsets, without realizing that the island itself is the remnant of a massive volcanic eruption. "When people are in Santorini, they just don't realize this is part of a volcano," she says. "I think that if people realized that, it would give them a different perspective of the landscape that they're looking at."

Whether it's hiking to the rim of Vesuvius, descending into a dormant magma chamber in Iceland, or exploring landscapes still shaped by geothermal activity, these are the volcanic destinations to visit.

What to know before visiting a volcano

One of the biggest misconceptions, according to Dr Jo, is the belief that visiting an active volcano guarantees witnessing an eruption. "Volcanoes are cyclical, and there's no guarantee," she says. "As a geologist, there are indicators and warnings where we can make some predictions that a volcanic episode could happen, but it's on its own time clock."

Travelers should also understand that not all volcanoes behave the same way. While explosive volcanoes such as Yellowstone or Mount Fuji are capable of major eruptions, others produce gentler volcanic activity that can often be observed safely from designated viewing areas. Understanding those differences helps visitors choose destinations that match their interests, whether that's photography, hiking, geology, or seeing active volcanic landscapes.

Some of the world's most popular volcano tourism destinations fall into this latter category. Iceland, for example, has become known for eruptions that can often be viewed from a safe distance when conditions allow, while Costa Rica's volcanic regions offer geothermal features such as hot springs, fumaroles, and sulfur vents that provide a glimpse into the Earth's activity without the drama of a major eruption.

For those planning a trip, Dr Jo recommends checking volcano monitoring websites before traveling, including the Smithsonian Institution's Global Volcanism Program and regional observatories, which provide real-time information on volcanic activity, alert levels, and access restrictions.

The world’s most fascinating volcanoes that travelers can safely experience

• 

  Mount Vesuvius, Italy

  Few volcanoes are as deeply intertwined with human history as Mount Vesuvius, whose eruption in AD 79 buried the Roman cities of Pompeii and Herculaneum. Yet for Dr Jo, it is the hiking experience itself that leaves the strongest impression.

  "One of my very favorite hikes was hiking the caldera of Mount Vesuvius," she says. "You're literally walking on that crater rim. There's no other volcanic hike that I've ever been on that has been that dramatic, where you truly understand you are walking on a volcano."

  Located just outside Naples, Vesuvius is one of the most accessible volcanoes in the world. Visitors can drive or take a shuttle partway up the mountain before completing a relatively short walk to the summit area. Along the trail, volcanic ash and rock from past eruptions provide a reminder of the mountain's destructive history, while viewpoints around the crater offer a close look into the volcano itself.

  The reward is not only the chance to stand on the rim of one of the world's most famous volcanoes, but also sweeping views across the Bay of Naples, with Pompeii, Naples, Sorrento, and Capri visible on clear days.

  Mount Stromboli, Italy

  For travelers hoping to witness an active volcano in action, few destinations rival Mount Stromboli. Rising from a small island in the Tyrrhenian Sea north of Sicily, it is one of the world's most active volcanoes and has been erupting almost continuously for around 2,000 years, earning the nickname "The Lighthouse of the Mediterranean."

  Unlike volcanoes that remain dormant for decades between eruptions, Stromboli is known for its regular bursts of activity, sending glowing fragments of lava, ash, and gas into the air at intervals throughout the day and night. One of the most popular ways to experience the volcano is by boat, with evening excursions offering views of eruptions illuminating the Sciara del Fuoco, a steep volcanic slope that descends into the sea.

  Visitors can also hike on the volcano with authorized local guides, though access is tightly regulated and subject to change depending on volcanic and weather conditions. For many travelers, the combination of black-sand beaches, dramatic coastal scenery, and the chance to witness one of nature's most reliable volcanic displays makes Stromboli one of Europe's most compelling volcano destinations.

  Þríhnúkagígur, Iceland

  For photography enthusiasts, Iceland remains Dr Jo's top recommendation. "If you're interested in photography and volcanology, I would send you to Iceland. It is the size of the state of Virginia, but it has 33 active volcanoes," she says. "Pretty much anywhere you're at in the landscape of Iceland, you are going to see a volcano or some type of volcanic feature."

  She also points to Iceland's extended summer daylight hours, which provide ideal conditions for landscape photography.

  While most volcano tourism focuses on what happens above ground, Iceland's Þríhnúkagígur offers a chance to venture inside one. The dormant volcano is the only place in the world where visitors can safely descend into a vast magma chamber left empty after an eruption thousands of years ago. Visitors can access the chamber by an open cable lift, revealing towering walls streaked with vibrant mineral colors.

• 

  Ometepe, Nicaragua

  Nicaragua is one of Dr Jo's top recommendations for travelers looking to get off the beaten path. She points to Ometepe, an island in Lake Nicaragua formed by two volcanoes connected by a narrow isthmus, as a destination that combines volcanic landscapes with dense tropical forest.

  The island's twin volcanoes offer two very different hiking experiences. Concepción, an active stratovolcano reaching 5,280 ft, is known for its near-perfect cone and remains one of the country's most recognizable landmarks. While it regularly emits vapor and occasionally produces minor ash eruptions, it is generally considered safe to climb with a guide. The demanding eight- to 10-hour ascent begins through farmland and forest before giving way to steep, exposed slopes near the summit.

  Maderas, by contrast, is dormant and more heavily forested. Rising to 4,573 ft, it is topped by a crater lagoon hidden within cloud forest. The six- to eight-hour trek passes through humid, moss-covered terrain rich in tropical plant life, with howler and capuchin monkeys often spotted among the trees. Together, the two volcanoes offer the chance to experience dramatically different volcanic landscapes on a single island.

  Cotopaxi, Ecuador

  If you're visiting Quito and want to see an active volcano without venturing too far from the city, Cotopaxi is one of the easiest and most rewarding options. Located around 30 miles south of the Ecuadorian capital, the volcano dominates the surrounding landscape with its snow-capped, almost perfectly symmetrical cone.

  At 19,347 ft, Cotopaxi is one of the world's highest active volcanoes, but you don't need to be a mountaineer to experience it. While experienced climbers can attempt the summit with a certified guide, most visitors come for hiking, cycling, horseback riding, and wildlife spotting within Cotopaxi National Park. One of the simplest ways to appreciate the volcano is from Laguna Limpiopungo, where an easy walking trail circles the lake and, on clear days, offers reflections of the peak in the water.

• 

  Poás Volcano, Costa Rica

  Costa Rica offers a very different kind of volcanic experience. As Dr Jo puts it, “You’re not necessarily going to see magma, but you do get to see and smell the sulfur coming up to the surface. You get hot springs and geothermal activity, which is a nice complement to volcanic landscapes.”

  Poás is one of the easiest ways to experience that up close. Located within Poás Volcano National Park, just a couple of hours from San José, it’s known for its large active crater, acidic lake, and constant plumes of steam rising from fumaroles around the rim. It’s active in a low-level, ongoing way rather than through dramatic eruptions, with the most recent significant eruptive period occurring in 2017–2018 after earlier major activity in the 20th century.

  The main crater is vast – around 1.3–1.5 kilometres wide and more than 300 metres deep – and on a clear day, you can look directly into its pale, steaming lake. A short trail also leads to the nearby Botos Lagoon, a cold, rain-fed crater filled with still water and surrounded by cloud forest.

• 

  Acatenango Volcano, Guatemala

  If you’re a keen hiker, visiting Acatenango must not be missed. Just outside Antigua, this volcano hike offers one of the most dramatic volcanic experiences in Central America. It sits directly opposite its highly active neighbor, Fuego, and the two are often hiked together in the same trip – Acatenango for the overnight climb and Fuego for the eruptions.

  The ascent to Acatenango is a full-day climb through shifting landscapes, starting in farmland and pine forest before giving way to increasingly cold, high-altitude terrain. Most itineraries break the hike with an overnight stay at a camp on the upper slopes, before an early hike to the summit for sunrise.

  The real draw is the view across the valley to Volcán de Fuego, one of the most consistently active volcanoes in the world. Come evening, hikers can often witness eruptions from their camp – bursts of glowing lava and ash lighting up the sky at regular intervals, sometimes accompanied by low rumbles that carry across the ridge.
