Suitable for people who have a lot of energy and an adventurous spirit if they want to come here... - If you want to come here, you need struggle and energy... but you will pay for it directly with the beauty of the crater which is so beautiful when it reaches its peak... you won't regret it if you come here... thank you Indotrip

Go for a walk with friends - Take a walk to a very beautiful place Very extraordinary tracking Rewarded with a fantastic view Ahahah Highly recommended for a trip with friends

Unforgettable - An experience that must be lived without a doubt. We were supposed to start the tour at 6 pm, but the driver didn't arrive until 8.15 pm. The walk from our hotel is long to the pier so we arrived quite late at the Ijen base camp and still had to have dinner. We didn't start the climb until 2.30/2.45 am. Our guide (Andy) was super friendly. He stopped every time we needed him, explained to us how the miners work there (he had worked for half of his life as a miner there), took us many photos and helped us at all times. The experience has made it unsurpassable. Perhaps if we had left the hotel earlier, we would have been able to see the "blue fire" from below, but it was not to be. Even so, it is more than recommended to make this trip. And if it can be with Andy as a guide, the better.

I would recommend this tour. The... - <p>I would recommend this tour. The volcano is incredible but it isn't for everyone. Its a tough climb overnight and journey from Bali is pretty long. The driver were very courteous and the tour guide was pretty average. There was a wait in a building/house that was unexpected, we had to wait until fellow travelers arrived so we'd leave as a group.</p>

The trek was a really good one. We... - <p>The trek was a really good one. We started pretty late in the evening. The staff were accommodating and friendly. They were concerned for our safety and advised us accordingly.</p>

A unique experience but there is a lot involved - The crater visit at night is a very unique experience, but there are risks involved, and the effort and issues you endure to get there may mean that it won't be worth it for some. On the plus side, if conditions are right, you may see some blue lights reflected in the fumes directly above the centre of the crater. After you climb back up to the lip of the crater, there is a reasonable view over the main crater lake and back towards Bali. If you like challenges, you will have ticked off a big one; having climbed down into the crater in the middle of the night and back up again in the morning, wearing a gas mask. On the down side, it is a 4-hour, boring, night-time trip across Bali in the evening (including dinner); having left Legian etc about 6 pm. One hour on the ferry and another hour or more to the Mt Ijen parking lot and a 30-minute wait till everything opens at 12:30. I only endured this because I was going to dive nearby at Permuteran over the next few days. You get back down to the parking lot about 7:30 am, then reverse the trip back across Bali. You won't get much sleep for a day and a half. Back to the actual hike. The walk up the mountain is very long (several kilometres) and very steep for the most part. You need to be fit or you will find it very hard going. The track is extremely dusty when dry, and the fine dust fills the air as there can be hundreds of people are walking up. You really should bring a dust mask, but nobody advises you of this. When you get to the crater lip, you see and smell the sulphur fumes. You need to don the sulphur mask at this point, which makes the steep, 1 km trip into the crater hard work, because it restricts your breathing and makes your heart work harder. Climbing back up is even more difficult. When you get further down the crater, the fumes get thicker, and you have to close your eyes because the fumes sting. When waiting to see the blue lights at the bottom, you can be covered in a dense fog of sulphur fumes for some time until the wind changes, or the fumes reduce. You can't take off your mask,and you can't open your eyes. You can't breakout and escape the fumes, and it is a long haul back up to get out of it. You just sit in the claustrophobic fog and hope that it will clear. You could hear heaps of people coughing and moaning in the fog. I'm guessing they were not wearing masks. BTW, I had to ask for one as we started to head up the track. Nobody had thought to get one for me. I rented a jacket but it was so hot walking up the track, that I had to carry it most of the way up. You do need it though, when the winds blow, and when you are in the crater. The blue lights that show up in the clouds of fumes are nothing as fantastic-looking as photos I have seen on the marketing photos. (I saw almost nothing). The 1 km climb back up to the crate lip, with the gas masks on, is hard work. As soon as the fumes clear a bit, you feel compelled to breathe some free air without the mask, and it may not do any damage for such a short space of time; but it can't be doing you any good either. Even walking back down the dirt track is dangerous. The guide said they have a lot of injuries at this point because people slip on the steep track that is covered in fine dust and tiny pebbles that work like ball bearings under your feet. I slipped on many occasions, even though I was being careful. 'Breakfast' at the bottom was pathetic. It consisted of a bowl of fried bananas and three boiled eggs. No utensils, napkins, salt or pepper or anywhere to wash your hands after the trek we had just been on. Only because I asked, I was led to a hovel of a kitchen where I could use some dishwashing liquid to wash my hands in a dish on the dirt floor. Tea and coffee options were almost zero. I know this is a poor area, but considering the fee paid, it could have been even a little better. I don't know that I could recommend this to most people.

The Volcano itself was fantastic... - <p>The Volcano itself was fantastic, challenging ascent, challenging descent into the crater with difficult conditions and amazing and spectacular scenery. It is tough, and you do need a decent level of fitness to manage it. The conditions are also incredibly unpleasant at the bottom of the crater, so be prepared for clouds of sulphur gas. IT IS WORTH IT THOUGH!</p> <p>The organisation of the tour that we were on left a lot to be desired. Our pickup time was changed twice, there was very little information on what the itinerary was, and there was a number of surprise stops on the journey to the volcano itself, the strangest of which was arriving in a semi-completed residential complex to wait for a while before travelling to the park. No prior warning that this was going to be the case and certainly an uneasy feeling associated with it.</p> <p>As with most Bali tours, the guides were more glorified drivers, with very little offered by way of guiding, more drive to a location and drop you off come find us when you're done</p> <p>So, in conclusion - go to the volcano, it's freaking awesome. Choose a different company to take you.</p>
