The hiking itself to the volcano is around 1.5 until 2 hours. Also, the trip to the bottom of the crater is around 30-40 minutes. Ijen carter itself is truly dramatic – the caldera has a lake that is bright green in colour and almost 100% pure sulphuric acid. It is 200 mt deep at its deepest and provides a fascinating focus to the volcano.

The best time to visit Ijen Crater Or ijen Volcano Or Kawah Ijen

The best day to visit this volcano is the dry season, mostly it starts from April until the beginning of November. Those months are the best time to visit Ijen Crater.

WORST TIME TO VISIT: Start from the end of December until March, there will be more rain that will start from Morning until night. From December until March the intensity of the fog in the Ijen Crater was lower. Thus, visitors can see the blue lake and blue fire without being blocked by fog.

What you can see in the Ijen crater

1. The blue fire phenomenon

The blue fire is a natural wonder that can only be seen at Ijen, It is only visible in the extreme darkness. If you are planning to witness the blue fire, you have to start walking at 2 AM. Once at the top you have to descend again into the crater, wearing a mask to find the blue fire.

2. Acidic Crater Lake

This beautiful warm lake with its blue-greenish water looks very inviting but it corrosive and dangerous! Kawah Ijen (Ijen crater) is the world’s largest highly acidic volcanic lake. The crater size is about 960 meters x 600 meters with a depth of 200 meters is so acidic that it can dissolve clothes and human flesh.

The acid measure is almost zero (pH<0.5) about similar to the strength of car battery acid. I tried to touch the water using my finger, it’s very warm and it tastes salty.

Please don’t try this, I got my finger itched for about 30minutes! The best time to go down to Ijen crater lake is in the morning between 4.00 to 9.00 am. Around 10 am the wind starting to blows the acid smokes of sulfur to the walking path.

It will be hard to climb down or up when it got covered with those sulfur smokes. If you are in this situation and you don’t have a mask, pour some water on the tissue or handkerchief.

2. Sulfur miner

Kawah Ijen has been a working sulfur mine since 1968 and you will come across a number of hardworking miners hauling heaving reed baskets of sulfur—weighing up to a mind-boggling 200 pounds—up and down the volcano on your hike.

In what has to be one of the toughest jobs in the world, many miners choose this line of work over farming in local areas thanks to its higher wage: roughly $10 a day (around 800 rupiahs per kilogram, based on two trips).
