Recently, the eruption of Mount Lewotobi Laki Laki in East Nusa Tenggara caused major disruptions, including more than 50 canceled flights to and from Bali. It’s a sharp reminder of the volcanic activity that shapes Bali and Indonesia as a whole. Sitting on the Pacific Ring of Fire, Indonesia is home to both active and dormant volcanoes that influence not just the island’s stunning landscapes but also its climate and culture.
The last Bali volcano eruption occurred on June 3rd, 2019 from the tallest mountain, Mount Agung. While eruptions like these are powerful reminders of nature’s force, Bali’s volcanoes are also a huge part of its charm, drawing adventurers and spiritual seekers alike.
Active Volcanoes in Bali
Bali’s volcanic landscape isn’t just beautiful, it’s alive. Two of its most famous volcanoes, Mount Agung and Mount Batur, offer adventure, stunning views, and a taste of Bali’s raw, natural power.
Mount Agung (Gunung Agung)
At 3,142 meters (10,311 feet), Mount Agung is Bali’s tallest and most sacred mountain. This massive stratovolcano is known for its steep slopes and powerful eruptions, making it one of the toughest hikes on the island. The trek to the top isn’t for the faint of heart, it’s intense and demands a solid level of fitness. But if you’re up for the challenge, the reward is worth it: jaw-dropping views of Bali and beyond.
Agung erupted most recently in 2019, sending volcanic ash soaring more than 12 kilometers into the air. While the eruption didn’t disrupt tourism much, it was a reminder of just how active this mountain is. Climbing Agung is not only an adventure but also a spiritual experience, as it’s a sacred site for the Balinese people. If you’re more into a mountain person, this guide is for you.
Mount Batur (Gunung Batur)
Looking for a more laid-back hike with epic views? Mount Batur has you covered. Located in Bali’s Kintamani region, this active volcano is famous for its sunrise treks. The hike is easier than Mount Agung’s, making it popular among tourists, especially those who want to catch the first light over Bali. The sunrise from the summit is nothing short of breathtaking, warm hues painting the sky as the island wakes up beneath you.
Hiking Mount Batur isn’t as fierce as its taller cousin, but it’s still an active volcano, and the experience is unforgettable. It’s a perfect spot for those looking to enjoy Bali’s natural beauty without the extreme challenge of a more difficult climb.

Safety Tips for Tourists in Bali During Volcanic Activity
Bali’s volcanic landscape is one of the island’s biggest draws, but with active volcanoes come some risks. Here’s how you can stay safe while exploring Bali’s mountains and still enjoy all the adventure they offer.
- Stay on Top of Volcanic Status Updates
Bali has some of the most active volcanoes in Indonesia, like Mount Agung, and eruptions do happen from time to time. While minor eruptions are common, it’s important to stay updated on the volcanic status. Indonesian authorities monitor these volcanoes closely and provide daily reports. If an eruption occurs or the volcanic activity increases, they’ll issue warnings so you can plan accordingly and stay safe. - Watch for Air Travel Disruptions
If you’re flying to or from Bali, keep an eye on the status of Denpasar Airport international flights. Ash clouds from an eruption, like the one Mount Lewitobi LakiLaki eruption occurred recently, can close Denpasar International Airport and disrupt air travel for days. While you’re on the island, make sure you’re aware of any changes to your flight plans. If you’re planning to leave Bali soon, check with your airline for updates about potential delays due to volcanic activity. - Lava Flows and Ash Clouds Can Be Dangerous
While lava flows are rare for most of Bali’s volcanoes, they can still pose a risk during more serious eruptions. Bali’s volcanoes, especially Mount Agung (the most active volcano on the island), are carefully watched by Indonesian authorities. If a dangerous eruption happens, lava flows could affect nearby areas, and ash clouds could disrupt your plans. If you’re close to an active volcano and ash starts to fall, stay indoors, cover your face with a mask, and avoid inhaling the ash. - Follow Evacuation Orders
In the rare event that a major eruption occurs, Indonesian authorities will issue evacuation orders. If you’re in an area near the volcano, follow these instructions immediately. Bali’s disaster management team has clear procedures in place to protect both locals and tourists. Keep in touch with your accommodation, stay informed through local news, and be ready to move quickly if needed. - Travel Insurance Is Key
Volcanic activity can sometimes cause flight cancellations or changes to your travel plans. It’s a good idea to have travel insurance that covers things like changes to international flights or last-minute accommodations in case of an eruption or flight delays.
How to Safely Explore Bali’s Volcanoes
Bali’s volcanoes are not only beautiful but also full of adventure. If you’re planning to explore the island’s mountain range, here are some tips to help you stay safe and get the most out of your trip.
- Stick to Designated Hiking Trails
Whether you’re hiking up an inactive volcano like Mount Bratan or tackling an active one like Mount Batur, always stick to the official trails. These routes are well-maintained and monitored for safety, especially near more active peaks like Mount Agung. Venturing off the path could put you at risk of injury or exposure to dangerous volcanic gases. - Book a Guided Tour
If you’re planning to hike one of Bali’s active volcanoes, like Mount Agung, it’s always a good idea to go with a guide. A local guide will know the mountain inside and out, and they’ll keep you safe from risks like lava flows or sudden eruptions. Plus, they can share cool stories about the volcano’s history and its connection to Bali’s culture and spirituality. - Be Prepared for the Unexpected
Even when trekking up dormant or inactive volcanoes, always be prepared. Volcanic terrain can change quickly, and conditions can be unpredictable. Bring plenty of water, wear sturdy footwear, and pack a mask in case of ash clouds. It’s better to be over-prepared than to get caught off guard, especially when you’re exploring an area with a history of volcanic activity. - Respect the Volcano’s Spiritual Significance
In Bali, volcanoes aren’t just stunning natural features—they’re also deeply spiritual. Mount Agung, for example, is considered sacred by the Balinese people, with temples like Pura Besakih sitting on its slopes. Be respectful of the mountain’s spiritual significance, especially when visiting temples or sacred sites.
