Merapi is the volcano Yogyakarta lives under, and in October 2026 it is still erupting. You cannot climb it, but you can ride an open jeep through the valleys its 2010 eruption buried. Here is how the lava tour works, what you will see, and how to fit it around Borobudur and Prambanan.
Can you climb Mount Merapi in 2026?
No. As of October 2026 every climbing route on Merapi is closed, and the Mount Merapi National Park office (Balai TNGM) says climbing is not recommended for anyone except disaster-mitigation researchers. The trails have been shut since 22 May 2018, and the volcano has been at Level III (Siaga) since 5 November 2020. BPPTKG, the agency that monitors Merapi, confirmed Level III again on 12 and 17 October 2026. When the MAGMA Indonesia app briefly showed Level I in mid-October, BPPTKG called it human error, so check more than one official channel.
Merapi is in an ongoing effusive eruption that began in late December 2020. Its southwest lava dome, about 4.18 million cubic metres in an October 2026 drone survey, sheds glowing lava avalanches most days; in one week at the end of September BPPTKG recorded 5 pyroclastic flows reaching up to 2 kilometres. The old Selo route on the north side lies entirely inside the danger zone, with Pasar Bubrah camp only about 0.7 kilometres from the summit. In July 2026 a rumour that it had reopened drew illegal climbers; the park says rangers remain at Selo and the closure stands.
What is the Merapi lava tour?
A ride in an open four-wheel-drive jeep, many of them vintage Willys-style machines, across the southern slopes the 2010 eruption buried. It starts from basecamps around Kaliurang and Cangkringan in Sleman, about an hour north of Yogyakarta, on sand and gravel tracks a normal car cannot handle. Each jeep takes up to four adults and is priced per jeep. Packages vary between basecamps, but the pattern published for 2026 looks like this:
| Package | Time | Typical stops |
|---|---|---|
| Short | 1.5 to 2 hours | Museum Sisa Hartaku, Batu Alien, Kali Kuning river |
| Medium | 2 to 2.5 hours | Short route plus Bunker Kaliadem and Mbah Maridjan's former home |
| Long | 3 to 3.5 hours | Medium route plus Mbah Maridjan's grave and a hilltop viewpoint |
| Sunrise | Departs around 04:30 | Bunker Kaliadem at first light, then the usual stops |
The medium route is the sensible minimum, because it adds Kaliadem and Kinahrejo, the two places that explain what happened. The sunrise departure is best for photography, since the summit is usually clearest at dawn. Book ahead on holiday weekends.
What will I see on the lava tour?
Bunker Kaliadem, usually the highest point the jeeps reach, roughly 4 kilometres from the summit, was built as a refuge from hot clouds. In June 2006 a pyroclastic flow buried it, and two volunteers sheltering inside died. It is now the classic sunrise stop, with Merapi straight ahead.
In Kinahrejo, Mbah Maridjan, Merapi's spiritual gatekeeper appointed by the Yogyakarta palace, refused to leave his home when the 2010 eruption began. He was found in his burnt house in a bowing position of prayer, aged 83. His former home is a small memorial, and the longer tours visit his grave.
Museum Sisa Hartaku, "the remains of my treasures", is a house in Kepuharjo holding what the hot clouds left: animal skeletons, motorbike frames, and a half-melted clock showing the hour the flow arrived. It is free with a donation box, open daily 08:00 to 17:00; give it more than five minutes. Batu Alien is a boulder carried kilometres in 2010, and most tours end splashing through the Kali Kuning river, a channel operators skip in heavy rain because it also carries lahars.
What happened in the 2010 eruption?
It was Merapi's largest since 1872. The eruption began at 17:02 on 26 October, and the strongest explosions came on the night of 4 to 5 November. It killed 386 people according to the final BNPB count (early tallies of around 340 to 350 are often still quoted), nearly 350,000 were evacuated, and more than 2,000 homes were destroyed. The exclusion zone grew in stages from 10 to 20 kilometres, and a USGS-backed study credits the forecasts with saving more than 10,000 and possibly more than 20,000 lives. Airports closed, and UNESCO notes that ash settled on Borobudur.
The Merapi Museum and Ketep Pass
The Museum Gunungapi Merapi, on Jalan Boyong in Hargobinangun, Pakem, explains the volcano's geology, eruption history and monitoring, with rock samples, an eruption simulation and a motorcycle wrecked at Kaliadem in 2006. It is worth visiting before the jeep tour. Recent listings give hours of about 08:00 to 15:00 from Tuesday to Sunday, with an earlier close on Fridays, so plan on it being shut on Mondays and confirm locally. Allow an hour.
To see Merapi without a jeep, go to Ketep Pass, at about 1,200 metres in Magelang, between Merapi and Merbabu. On a clear morning it looks onto Merapi's summit and across to Merbabu, Sindoro, Sumbing and Slamet, and it has a small volcano museum and theatre, open daily from 08:00 to 17:00. Go early or late: by midday the summit is usually in cloud.
Getting there, and combining it with the temples
Fly into Yogyakarta International Airport (YIA) or arrive by train. There is no public transport to the tour sites, so take a jeep package with hotel pick-up or a car and driver to the basecamp. Kaliurang, an old hill resort with cooler nights, cuts the pre-dawn drive to minutes; the city suits you better if you are also visiting the temples.
Most people do a sunrise jeep tour, leaving Yogyakarta around 03:30, then the Merapi Museum if it is not a Monday, and Prambanan for the late light, the simpler drive from Cangkringan. Keep Borobudur, about 40 kilometres northwest of the city, for a separate morning with Ketep Pass on the way back. Both temple compounds have been UNESCO World Heritage sites since 1991.
Is the Merapi lava tour safe?
Reasonably, with a licensed operator who follows BPPTKG's danger zones, but it is not risk-free. BPPTKG's current recommendation keeps people out of a 3 km radius around the summit and out of the river valleys where flows could reach: in the south to southwest sector up to 5 km along the Boyong and up to 7 km along the Bedog, Krasak and Bebeng; and in the southeast up to 3 km along the Woro and 5 km along the Gendol. Tours run outside these lines, and the zones change as the dome grows, so an operator may skip a stop that was open last month.
Check BPPTKG's daily report and MAGMA Indonesia the day before, never cross a barrier, and respect lahar warnings: heavy rain upstream can send mudflows down a dry channel with little warning. The everyday risks are the open jeep and the river crossing, so hold on, and bring closed shoes, a buff, a light jacket for sunrise and dry clothes for after Kali Kuning.
Quick answers
When is the best time for the lava tour?
At dawn, in the dry season, roughly May to September. Skies over the summit are usually clearest until about 10:00. From November to March the mountain is often hidden and rain can trigger lahars; whatever the month, Merapi's activity decides what is open.
How long does the Merapi lava tour take?
From about 90 minutes to three and a half hours. Allow half a day with the museum, and two days to add Borobudur, Prambanan and Ketep Pass without rushing.
Can I climb a nearby volcano instead?
Merbabu is the usual alternative when its own trails are open; check its rules first. Do not join an operator offering a "quiet" Selo climb on Merapi.
How do people on the slopes see Merapi?
For many Javanese it is a kingdom of spirits as well as a volcano, and the palace still sends labuhan offerings up the slope each year. Kinahrejo and the memorials are places of mourning. More on our Mount Merapi volcano page.
Our Discover Indonesia: Mount Merapi, Yogyakarta and Java guides cover the slopes and the temples in more depth. Browse them all on our guides page.
Facts checked October 2026. Merapi's alert level, danger zones and open tour stops change with the volcano's activity; check BPPTKG, MAGMA Indonesia and the Mount Merapi National Park office (TNGM) before you go, and confirm museum hours locally.
