These treks showcase some of Indonesia's most spectacular volcanoes, viewpoints, wildlife encounters, and natural wonders.

Best for: First-time trekkers

Good to know:

• Type of hike: Volcano sunrise trek
• Difficulty: Easy to moderate
• Typical duration: Two to four hours return

Mount Batur is one of Indonesia's most accessible volcano hikes and one of Bali's most popular outdoor experiences. The hike begins before dawn, with the trail climbing steadily towards the summit, where hikers are rewarded with sunrise views across Lake Batur, Mount Agung, and the surrounding highlands. The relatively short climb makes it ideal for travellers looking to experience volcano trekking without committing to a multi-day expedition.

After your hike, you can extend your adventure north to Sekumpul Waterfall, often regarded as Bali's most spectacular waterfall. Hidden within a lush valley, the falls are reached via a scenic trek through rice fields, forest trails, and river crossings. Discover more hidden gems in Bali.

Travel tip: Take a warm jacket for the wait at the summit and wear hiking shoes with good grip, as parts of the trail are rocky and sandy.

Best for: Experienced hikers

Good to know:

• Type of hike: Challenging volcano ascent
• Difficulty: Challenging
• Typical duration: Eight to 12 hours return

As Bali’s highest mountain, Mount Agung offers one of the island’s most demanding and memorable hikes. Most sunrise treks begin at night, passing through forest before the trail becomes steeper and rockier higher up the mountain. As morning arrives, you may see Bali’s coastline, neighbouring Lombok, and the ocean stretching beyond the island.

Your experience will depend on the route you choose. The popular Pura Pasar Agung route reaches the southern crater peak, while the longer Besakih route continues through forest and rocky terrain to Mount Agung’s highest point. Both routes require good fitness and experience on steep mountain trails.

Safety tip: Check MAGMA Indonesia and confirm your route is open before climbing Mount Agung. Travel with an experienced local guide, bring water and warm layers, and follow local advice if volcanic or weather conditions change.

Best for: Bucket-list adventurers

Good to know:

• Type of hike: Multi-day volcano trek
• Difficulty: Challenging
• Typical duration: Two to four days

Rising 3,726 metres above Lombok, Mount Rinjani takes you through several landscapes in one unforgettable trek. Depending on your route, you may walk through tropical forest, cross open grasslands, camp on the crater rim, and descend towards the blue waters of Segara Anak Lake. From the rim, you can look down across the lake, with Mount Barujari rising from its centre.

Reaching the summit is a major challenge, but it isn’t the only rewarding way to experience Mount Rinjani. You can also hike Pergasingan Hill before Mount Rinjani as a shorter introduction to Lombok’s mountain trails, or choose it as an alternative if you can’t commit to a multi-day trek.

Safety tip: Check the latest Mount Rinjani trail closures before travelling, as route access can change. Confirm your route with your trekking operator and never enter a closed trail.

Best for: Unique natural phenomena

Good to know:

• Type of hike: Volcano crater trek
• Difficulty: Moderate
• Typical duration: Two to three hours return

Ijen Crater is famous for its electric-blue flames and striking turquoise crater lake. The hike begins before sunrise, giving you the chance to witness one of the world’s rarest natural spectacles before daylight illuminates the volcanic landscape. It's one of Indonesia's most distinctive outdoor experiences.

Safety tip: Ijen is an active volcano, and its crater contains highly acidic water and sulphur vents. Check MAGMA Indonesia for volcanic updates and BBKSDA East Java for park access information before travelling. Stay within permitted areas and follow instructions from guides and park officers.

Grand Mercure Malang Mirama is a comfortable base for exploring East Java's volcanic region. It's well positioned for travellers planning to combine the Mount Ijen hike with visits to Baluran National Park, Mount Bromo, and other highlights across East Java.

Best for: Sunrise photography

Good to know:

• Type of hike: Volcano and viewpoint trek
• Difficulty: Easy
• Typical duration: One to three hours

Mount Bromo’s setting makes it one of Indonesia’s most photographed volcanic landscapes. Start before dawn for sunrise across the Tengger Caldera, then cross the vast Sea of Sand and continue on foot towards the crater. Complete the experience with a 4x4 journey through the Whispering Sands and the green hills and savannah of Teletubbies Hill.

Mount Bromo fits naturally into a wider journey across Java and Bali. Add it to a two-week Indonesia itinerary after Yogyakarta, then continue through East Java or travel onward to Bali. While you’re in the region, visit Tumpak Sewu Waterfall, where streams of water fall into a deep canyon surrounded by rainforest.

Best for: Photographers

Good to know:

• Type of hike: Coastal island trek
• Difficulty: Easy to moderate
• Typical duration: One to two hours return

After the hike, continue to Pink Beach for a swim or snorkelling excursion, join a boat trip to look for manta rays, explore more of Komodo National Park by boat, or finish with a sunset cruise through the surrounding islands.

Travel tip: Plan your hike for early morning and avoid the hotter middle of the day. Padar Island’s hills are usually greener during wetter months and golden-brown in the dry season.

Best for: Wildlife lovers

Good to know:

• Type of hike: National park trek
• Difficulty: Easy to moderate
• Typical duration: One to three hours

Few hikes offer the chance to explore the natural habitat of the world’s largest lizard. On a ranger-led trek through Komodo Island, you’ll cross dry savannah and rugged coastal terrain while looking for Komodo dragons in the wild. Wildlife sightings aren’t guaranteed, but the walk reveals why Komodo National Park is protected as a UNESCO World Heritage Site, with its rare wildlife, dry hills, sandy beaches, and coral-rich waters.

You can also visit Rinca Island for another ranger-led trek through Komodo dragon habitat and a different view of the national park’s savannah landscape.

Wildlife tip: Komodo dragons are wild animals and can move quickly over short distances. Stay with your ranger, keep the group together, and maintain the distance specified by your ranger.

Best for: Adventure travellers

Good to know:

• Type of hike: Active volcano trek
• Difficulty: Challenging
• Typical duration: Varies by access conditions and chosen experience

Rising above Yogyakarta, Mount Merapi offers a striking look at Central Java’s volcanic landscape. When access permits, guided routes cross forest and dark terrain shaped by past eruptions, with views across the surrounding mountains and valleys. If climbing routes are closed, explore the lower slopes with an approved local guide.

Continue your experience with a visit to Prambanan Temple. Built in the 10th century, the UNESCO-listed complex features towering temples dedicated to Shiva, Vishnu, and Brahma, along with stone reliefs illustrating the Ramayana. It's one of Yogyakarta's most recognisable landmarks.

Safety tip: Check the latest Mount Merapi activity reports and MAGMA Indonesia before travelling. Access can change, so stay outside exclusion zones and only join routes approved by local authorities.

Best for: Campers and sunrise seekers

Good to know:

• Type of hike: Mountain summit trek
• Difficulty: Easy to moderate
• Typical duration: Three to five hours return

Mount Prau is known among Indonesian hikers for its spectacular sunrise views. Complete the hike in a day or camp overnight, then wake before dawn to see Mount Sindoro and Mount Sumbing rising above the clouds when skies are clear. The mountain has six official base camps, including Patak Banteng and Dieng, giving you several routes to choose from.

Packing tip: Expect cool conditions before sunrise, often around 10–15°C, although temperatures vary with the season and weather. Wear several light layers and carry a packable puffer or insulated jacket for the summit.

Best for: Landscape lovers

Good to know:

• Type of hike: Volcano crater walk
• Difficulty: Easy
• Typical duration: One to two hours return

Kelimutu is known for three crater lakes whose colours change over time. A short walk leads from the parking area to the viewpoints, making this one of Indonesia’s more accessible volcano experiences. Arrive before sunrise to watch the morning light reach the lakes and surrounding Flores highlands, although mist and cloud can affect visibility.

After visiting Kelimutu, continue to Moni Village for a quieter look at life in the highlands. You can also visit Wologai Traditional Village to see traditional houses, sacred stone altars, and ceremonial spaces connected to the culture of the Lio people. Together, these experiences connect Flores’ volcanic landscape with the traditions of the communities living around it.

Cultural tip: Remember that traditional villages around Kelimutu are living communities. Follow your guide, ask before taking photographs, respect sacred spaces, and support local artisans by buying handwoven tenun textiles.

Indonesia offers incredible trekking opportunities, but preparation is essential. Before heading out, keep these safety tips in mind:

• Wear hiking shoes with good grip, particularly on volcanic terrain.
• Carry plenty of water, especially during dry-season hikes.
• Pack a lightweight rain jacket, as mountain weather can change quickly.
• Carry a head torch for sunrise hikes.
• Follow instructions from local guides and national park authorities.
• Check volcanic activity alerts before travelling.
• Bring sun protection, including sunscreen, sunglasses, and a hat.
• Never hike alone on remote or challenging trails.
• Allow extra time for travel, as mountain roads can be slow and winding.
• Respect local customs and protected natural environments.

Indonesia's hiking trails offer far more than summit views. From Bali's volcanoes and Lombok's crater lakes to Komodo National Park and Flores' colourful landscapes, each destination presents a different side of the archipelago.
