While watching huge ash clouds being sent up into the sky or peering right into the glowing crater rim of some of these active volcanoes is not possible now, many of the world's active volcanoes can usually be explored up close. If you are planning a trip to any of these rumbling wonders after all, remember to check travel advice and COVID-19 health information, opening times and guidelines.

In 2010, newsreaders around the world struggled to pronounce the name of the Icelandic glacier volcano that brought air traffic in Europe to a standstill. Eyjafjallajökull belched out huge ash clouds that hung in the air for more than six days. 

Although it’s too dangerous to walk on the ice cap that covers the caldera of the volcano, hikers can explore the rocky terrain on the 15-mile (25km) Fimmvörðuháls ridge hike – snaking between the Eyjafjallajökull and Mýrdalsjökull glaciers, craters and lava flow formed by the 2010 eruption, it's equally intimidating and gorgeous.

The cone of Mount Vesuvius looms large over the city of Naples in southern Italy. The vast crater at its summit was formed during the last eruption in 1944 – and it’s not a question of if the volcano will erupt again, but when.

The once prosperous Roman city of Pompeii at the southeastern base of Mount Vesuvius was devastated by an eruption in AD 79 that rained down ash and volcanic rock. When the city was rediscovered nearly 2,000 years later, everything, from buildings and even food and jewellery, had been perfectly preserved. Check out Pompeii's secrets that are only just being uncovered.

Around 60 miles (100km) from Tokyo, Mount Fuji is Japan’s most iconic peak and some would say that the snow-capped view is best appreciated from afar. Fuji-san, as it’s known locally, is long overdue an eruption as the last time it happened was 1707.

The official climbing season is July to mid-September when the weather is relatively mild, however, all routes have been closed for the 2020 summer season. Normally, there are dozens of mountain huts on various trails offering bed and breakfast to overnight visitors who then tackle the summit in the early morning before it’s shrouded in cloud.

Just 30 miles (48km) off of the coast of New Zealand’s North Island, in the Bay of Plenty, White Island (Whakaari to the Māori) is a grumbling volcanic island of billowing steam and bubbling mud. Most of the volcano is below sea level so typically visitors step straight off the boats into the actual crater.

The otherworldly landscape is tinged yellow from the sulphur – the smell can be overwhelming and all visitors to White Island are issued with a gas mask and a hard hat. It last erupted in 2019 with tourists out on the crater and in boats in the water nearby. Sadly, 20 people perished in the eruption and tours have been suspended ever since.

The 3,000-square-mile Virunga National Park in the Democratic Republic of the Congo is home to a quarter of the world’s critically endangered mountain gorillas. The park, Africa’s oldest, is one of the top places to see rare wildlife and also trek to the summit of Mount Nyiragongo on a guided hike. Typically, treks are four to six hours and include an overnight stay in a summit shelter.

Mount Nyiragongo has the world’s largest lava lake and after dark is the best time to peer into the crater and see the glowing molten rock. The unusual fluidity of the lava makes it all the more dangerous to the people living in its shadow – more than a hundred villagers were killed in a devastating eruption in 2002.

The world’s smallest active volcano is famous for sitting in a lake within a volcano. The still green water belies the fact that it’s a volatile area – Taal is the country's second most active volcano and its most recent eruption in January 2020 spewed ashes over Calabarzon, Metro Manila and some parts of Central Luzon and Ilocos Region. This resulted in the suspension of school, work and flights in the area.

Outrigger canoes ferry passengers from Talisay to Volcano Island in around 30 minutes and from the dock, a well-worn dusty trail leads to the crater lake and its pretty views. However, since the latest eruption, visiting the volcano is strictly prohibited.

Cotopaxi is among the world’s highest volcanoes, reaching a height of 19,347 feet (5,897m) so any ascent requires mountaineering equipment suitable for a glacier climb as well as plenty of time to acclimatise. The summit reopened to climbers in 2017 after a major eruption two years earlier, but new travel restrictions are now in place due to the COVID-19 pandemic.

The near-perfect snow cone of Cotopaxi can be seen from as far as Ecuador’s capital city, Quito, about 35 miles (56km) away. Mountain bikers can take the steep downhill from the base just below glacier level or bike the trails in Cotopaxi National Park with the volcano as a scenic backdrop.

Kīlauea, on Hawaii’s Big Island, had been constantly erupting molten lava since 1983 until the eruption was finally declared to have ended on 5 December 2018 after 90 days of inactivity. The name Kīlauea means much spreading or spewing in Hawaiian – a reference to its frequent outpouring of lava that flows into the ocean.

Typically, visitors can take a helicopter tour to view the caldera from above and get up close to the bubbling lava fields. The volcano can also be explored independently by looping round the Crater Rim Drive and stopping at a number of signposted trails to viewpoints. Located within the Hawai'i Volcanoes National Park, the volcano is currently open to visitors.

Telica is a steep-sided cone-shaped volcano on the west coast of Nicaragua. It's possible to hike right up to the smoking crater and camp just below it. The walk is an arduous six hours usually done with a guide as the trails are not signposted. The volcano's last eruption was as recent as 29 July 2020.

For an easier journey up the volcano, it's possible to hire a Jeep to give travellers a lift to a trailhead that's just 45 minutes from the peak. However, the bubbling mud pools, hard rock and steep incline make it a bumpy (and not very pleasant) journey. 

Villarrica, along with Quetrupillán and the Chilean portion of Lanín, falls inside Villarrica National Park in Chile’s central valley. Permanently active, the glacier volcano often has a lava lake at its summit.

Villarrica was closed for expeditions in 2015 when an eruption blasted out ash and lava and caused more than 3,000 people to be evacuated from nearby homes. In 2019 before the coronavirus pandemic it reopened and offered travellers an option to use a ski lift part way up and then tackle the snow and ice to reach the summit at 9,380 feet (2,860m).

Defined by incredible volcanic landscape of geysers and hot springs, the Yellowstone caldera is a supervolcano that hasn’t erupted for around 70,000 years – though beneath ground, it's still very much active.

Seismic activity at Yellowstone is closely monitored and there are between 1,000 and 3,000 earthquakes below ground each year. In fact, in April 2019, a series of tremors prompted some scientists to believe these could be a sign it's about to blow... Read more about Yellowstone in our guide to Northern Wyoming.

The highest active volcano in Europe, Mount Etna is a magnificent landmark in the northeast of Sicily. Fiery Etna erupts several times a year and is sometimes closed for safety reasons.

When it is safe to visit, it's possible to hike up the impressive volcano or there’s a 20-minute cable car (Funivia dell’Etna) up the south side of the mountain. Afterwards, it’s either a long walk or a short 4x4 drive through the barren landscape to the otherworldly summit craters.

Mount Teide is one of Europe's most easily accessible volcanoes as it's located on the volcanic island of Tenerife, one of Spain’s Canary Islands. Despite a seismic swarm (a series of mini earthquakes) in 2016 and 2017, scientists say they aren’t concerned about an imminent eruption (low level seismic activity is very normal).

At 12,198 feet (3,718m), El Pico del Teide is the highest point in Spain. Part of the Teide National Park, visiting the volcano is usually very simple. First, visitors have to obtain a free permit for entry, then most drive to the base station where a cable car zips to the upper station. Here, several trails lead to the peak. 

Dormant (meaning inactive) for hundreds of years, a fearsome eruption in 1968 devastated nearby villages, reminding of the power inside it. Between then and 2010, Arenal rumbled on, regularly spewing smoke, ash and lava, but for the last 10 years the volcano has been slumbering quietly once more.

Arenal National Park is a lush green paradise with trails to explore the forest and old lava flows. The peak is still part of a 2.5-mile (4km) exclusion zone, but various routes take in gorgeous viewpoints – all best viewed at sunrise. These are the most dangerous beaches in the world. 

Mexico has more than 3,000 volcanoes but only 14 of these are considered active. The Volcán de Colima (also known as the Volcán de Fuego) is one of the most volatile and explosive eruptions in January 2017 triggered mass evacuations. 

Hiking up Volcán de Colima obviously isn't allowed as it's just too dangerous, but many decide to climb the nearby Nevado de Colima for spectacular views. With Nevado de Colima's peak reaching a height of 8,924 feet (2,720m), it offers jaw-dropping views of the menacing volcano and its smoking cone.

Mount Pelée on the Caribbean island of Martinique looks peaceful but in 1902 a deadly eruption wiped out an entire city, killing around 30,000 people. Saint-Pierre was never fully rebuilt, however, today there are a few villages that have sprung up in its place. The volcano's last eruption was in 1932 and it's still considered active.

Also the highest peak in Martinique at 4,583 feet (1,397m), Pelée has several trails to explore the slopes and peak. The views of the bay and its black volcanic sands, when it’s not too foggy, are phenomenal. Discover secrets of the world's most beautiful mountains.

Gorgeous Tanna Island is home to Mount Yasur, the best-known of the Vanuatu volcanoes. The trail from the car park to the awe-inspiring crater rim only takes about 10 minutes to walk – possibly the easiest volcano climb in the world. However, to preserve the nature surrounding the volcano, travellers can only enter via a visitor centre for a pick-up truck ride up a bumpy trail through the jungle to just below the crater.

Said to have been constantly bubbling and smoking for more than 800 years, even attracting Captain James Cook with its glow, the summit can still be a dangerous place as the volcano is known for shooting out burning debris high into the air. When the volcanic activity picks up, the crater might be off-limits or closed completely.

In the Cascade Range in Washington State, Mount St Helens is infamous for its 1980 eruption in which 57 people lost their lives. The Mount St Helens National Volcanic Monument was created to preserve the volcano and constantly monitor it for unusual seismic activity.

The viewing deck at Johnston Ridge Observatory is the best place for a magnificent view of the crater of Mount St Helens as well as the lava dome and the blast zone. The short eruption trail from here has information and eye-witness accounts from the fateful eruption on 18 May 1980. Now take a look at jaw-dropping places you can only see in photos.

Sitting on the Ring of Fire – a horseshoe-shaped area associated with most earthquakes and volcanic eruptions – at the edge of the Pacific Ocean, East Java is home to the Bromo Tengger Semeru National Park. This vast sandy caldera boasts the famous smoking Mount Bromo that towers and impressive 7,641 feet (2,329m).

Normally, the majority of visitors book onto a tour and travel by Jeep in the early hours of the morning to a viewpoint to watch the sunrise over Mount Bromo. Then a sea of sand has to be crossed to get anywhere near the actual crater – it's possible to hike, but usually locals offer bike or horseback rides.

The small city of Antigua in Guatemala has a knot of volcanoes to the southwest – Agua, Acatenango and Fuego. Fuego is the most active, erupting as recently as June 2018, when mudflow from the eruptions, ash and fast-moving currents of hot gas blanketed nearby villages killing more than 190 people. Nearly 4,000 people had to be evacuated again in November 2018, when the volcano began violently erupting again.

Eruptions from Volcán de Fuego – Spanish for Fire Volcano – can be seen from Antigua, but some still take on the strenuous hike up Acatenango for a unique view of the glowering peak. Setting out from camp in the early hours to watch the volcano spit up stones, fire and smoke is an unforgettable, but dangerous experience. Occasionally, access to the volcano is restricted due to its activity.
