Mandatory Equipment for Climbing Ijen Crater

Climbers of Mount Ijen, especially Ijen Crater, can be done with online reservations through tiket.bbksdajatim.org and must show a health card from a doctor. Climbing is usually done at night to see the blue fire.

The average duration of the climb is around 2-2.5 hours with a distance of 3.4 km to the top of the mountain. The climbing path is quite well-organized and safe, with some fairly tiring uphill corners. Paltuding Post is the gateway to the Ijen Crater Tourism Park, located at an altitude of + 1,800 meters above sea level.

Climbing Ijen Crater, especially to witness the famous blue fire phenomenon, requires thorough preparation. Here is a list of equipment that must be brought to make the trip safer and more comfortable:

1. Safety and Navigation Equipment

• Gas Mask – Ijen Crater emits sulfur gas that is dangerous for breathing. Use a gas mask or respirator with a filter for maximum protection.
• Flashlight or Headlamp – Climbing is usually done early in the morning in dark conditions, so lighting is very important. A headlamp is more recommended so that hands remain free to move.
• Map or GPS – Although the climbing route is quite clear, bringing backup navigation is still necessary to avoid getting lost.

2. Clothing and Supporting Equipment

• Thick Jacket or Windbreaker – The temperature at the peak can reach 2–10 degrees Celsius, so a jacket that can withstand the cold and wind is essential.
• Gloves and Hats – Help protect hands and head from the piercing cold.
• Comfortable Trekking Pants – Choose pants made of lightweight, flexible, and stay warm for easy movement.
• Hiking Boots – The path to the summit is rocky and sandy, so shoes with good grip are needed to avoid slipping.

3. Other Supporting Equipment

• Protective Glasses – Useful for protecting the eyes from thick sulfur fumes.
• Trekking Pole (Optional) – Can help maintain balance and reduce the burden on the knees, especially when climbing or descending.
• Daypack (Small Bag) – Bring a medium-sized bag that is large enough to store water, snacks, and other equipment without weighing down the trip.

4. Food and Drink

• Sufficient Drinking Water – Dehydration can occur at high altitudes, so it is recommended to bring at least one liter of water.
• Snacks or Energy Bars – Snacks such as chocolate, nuts, or bread can be a source of energy during the trip.
• A Thermos with Hot Drinks – Drinks such as tea or coffee can help warm the body at the summit.

5. Documentation Equipment

• Camera or Smartphone with Spare Battery – Make sure the battery life is long enough because cold temperatures can speed up the power drain.
• Power Bank – Useful for recharging electronic devices while on the trip.
• Tripod or Monopod (Optional) – Helps in taking more stable pictures, especially when recording blue fire or panorama of Ijen Crater.

6. Medication and Personal Needs

• Personal Medication – If you have a history of certain diseases such as asthma or hypertension, make sure to bring the necessary medications.
• Wound Plasters and Simple First Aid Kit – Useful if minor injuries occur due to falling or being rubbed by rocks.
• Wet and Dry Tissues – Useful for cleaning hands or face after being exposed to dust or sweat.

Additional Tips

• Start climbing around 01.00 to 02.00 in the morning so you can reach the peak before sunrise and see the blue fire that is only visible in the dark.
• Use a local guide if it is your first time climbing Ijen Crater.
• Avoid staying too long near the crater if the sulfur smoke is too thick, because it can be dangerous for breathing.

By bringing the right equipment, the journey to climb Ijen Crater will be safer and more enjoyable. If you are not strong enough to climb up or down, you can use the trolley service pushed or pulled by local residents.**
