Important safety note (read before planning):
Mount Agung is an active volcano, and climbing rules can change quickly. Always check MAGMA Indonesia/PVMBG updates before booking, and follow the official hazard zone (“Zona Perkiraan Bahaya”) and any local closures.
Why this matters:
- PVMBG hazard zones are dynamic and can change at any time.
- Example guidance: at Level II (Waspada), PVMBG has advised no hiking and no activity within a 2 km radius of the crater. At higher activity levels, the restricted radius can be larger.
*Last reviewed: February 2026.
Also: Mount Agung may close during major religious ceremonies (for example, closures were announced around Besakih ceremonies in 2025). If the mountain is closed, don’t try to “sneak it” — reschedule.
Tips on Surviving a Climb up Mount Agung
Did you like our tale of a daunting, rain-filled trek up Mount Batur? If so, you are going to love our survival guide to hiking Batur’s taller, more formidable big sister, Mount Agung. As the highest peak and the most sacred point in Bali, this active stratovolcano stands at 3,031 meters (9,944 feet) and tempts the craziest of travellers and island residents to reach its summit.
At the bottom of the mountain stand the holy temples of Pura Besakih and Pura Pasar Agung, a site located some 200 steps from the parking area and the first gauntlet of the trek if you choose to depart from here. For anyone thinking of conquering this beast, make sure to follow these eight rules for the experience of a lifetime.
1. Know Your Physical Ability and Limits
I’m not going to lie to you, climbing Mount Agung was the hardest thing I’ve ever done. The same was said by the friends I went with, all of whom I consider to be in good, if not great, physical condition. Unlike other hikes I’ve done in the past, there are no switchback trails on the volcano; just a path (sometimes) angled at 45 degrees. The journey can be broken down into three different trekking environments:
- The first leg consists of a dirt path winding up through a thick forest of trees
- The second and longest leg is made up of boulders you first walk through, and subsequently take larger steps up to reach the next one
- The last leg of Agung is the steepest and by far the most dangerous as you have to scramble up the face of the mountain on all fours with no ropes or harnesses holding you in.
If you aren’t looking for an adrenaline rush, this trek is not for you! Somehow, just when we were questioning our strength as human beings and how we were realistically going to get down, the worst of it was over and we had reached the top.
2. Be Prepared to Hike on Zero Sleep
To reach the top of the mountain for sunrise, you have to begin the four-hour climb by 2:30 am at the latest. This meant that our alarm woke us up at 11:45 pm, and we were on the road from Sanur by midnight.
“Good morning? Good night?” No one knew; it was like we were in the Twilight Zone. You have two sleep options for this bizarre wake-up time: either don’t sleep at all or go to bed when the sun is still up. Neither is very realistic, so you’ll probably end up just staying awake and then passing out on the car ride there.
If you’re one of those freaky insomniacs, then this won’t be an issue for you, but if sleep is an essential energy factor for you to trek over 1,500 meters, then I suggest you stay somewhere closer to the volcano’s starting point for maximum shut-eye time.

3. And in The Dark…
Thank goodness for the invention of headlamps!
A phone flashlight isn’t the same as a real headlamp. You’ll want both hands free for balance, especially on steep sections.
Bring:
- headlamp (primary light)
- spare batteries or a backup light
- a small power bank for your phone
4. Hydration and Altitude: Take It Seriously
Mount Agung sits close to 10,000 ft elevation, and altitude illness is possible — especially with heavy exertion and dehydration. Though Wikipedia claims that altitude sickness is not a risk on Agung, I assure you it is (I should know, it smacked me in the face mid-climb)!
Drink consistently, bring enough water, and use electrolytes if needed. Effects include nausea, vomiting, dizziness, feeling cold, and other fun symptoms. This can happen for a number of reasons, including physical activity at high altitude and extreme dehydration.
To avoid this inconvenience, make sure to bring and drink as much water as possible throughout the extent of the climb. We all brought two full bottles each, ran out halfway through and thought we were on the verge of death. Don’t do this. Pack that H2O and gulp it down before, during and after.
5. Don’t Ask How Much Further You Have to Go
After about an hour or so of climbing, our friend made the mistake of asking our current status, in the hope that our guide would say something like, “You’re halfway there, congratulations!”
The minute he asked, though, I knew I wasn’t going to like whatever answer we were about to hear. Our legs were already burning, and the sun wasn’t even close to rising. When he responded that we were about a third of the way up the mountain, the thought of turning back crossed each of our minds. During an activity that takes so much mental endurance, ignorance is bliss, I promise you.
6. Go with Friends
Trekking Agung with friends is sure to provide precious memories and a sense of accomplishment that will last you all a lifetime, sure.
But more than a bonding moment, friends are truly necessary for an Agung climb. They’ll be an essential crutch when you believe you are about to collapse with exhaustion and don’t think you can continue on one more step. Plus, you can switch off giving each other piggyback rides to ease the pain.
7. Hire a Licensed Local Guide
Though it is not mandatory, it is HIGHLY recommended to climb Agung with a guide; it would have been nearly impossible to navigate to the top without their expertise. You can either look online or hire one upon arrival at the Agung base point.
When booking, confirm:
- route (Pasar Agung vs Besakih options vary by operator)
- what’s included (transport, water/snacks, entrance fees)
- turnaround policy (what happens if weather or conditions change)
Booking tip:
- ask your villa manager/hotel to arrange a reputable guide or operator,
- avoid “random last-minute deals” with unclear inclusions
8. Bring a Camera
This one is an obvious essential. Who in this day and age would push their physical and mental capacities to the limit without a photo to show for it? And it just so happens that the views from Mount Agung’s peaks are worth the gruelling ascent.
If you time it right, you should reach the top just as the sun’s first rays crest over the ocean. Luckily for us, it was a crystal clear morning, and we could see Lombok’s Mount Rinjani on one side and Java’s Mount Bromo on the other.
One of the best images came from Mount Agung casting its shadow over the rest of Bali.
… and this Hindu shrine greeting us good morning.
Once the sun had come up, we were able to finally see what we had been climbing for the last four hours. The descent took just under four hours and we were able to reach the car by 10:30am.
Also, I wasn’t going to say what I’m about to say, but it would be selfish to keep any valuable climbing advice to myself, right? So here is the PSA: remember to trim your toenails in advance because going downhill for four hours is pretty brutal on the front of your feet! And there you have it, possibly the most helpful tidbit of information you’ll receive about the Agung trek.
Heck, forget all of the rules – just be prepared to have your mind blown! Summiting Mount Agung was truly one of the most demanding but ultimately rewarding endeavours I’ve ever taken on and if you’re up for the challenge, it is the best activity you can check off of your Bali Bucket List.
