2. Physical Preparation for the Hike
One of the most important thing in this Ijen Crater Trip Guide is to prepare your physique. Hiking a mountain with its natural terrain requires one to have a fit condition. The same applies for the hike to Ijen Crater. It’s a 3 km trail with 518 m of elevation gain starting from 1.850 m to 2.368 m above sea level, consisting of some steep hills, even ground, narrow and rocky trail with volcanic ash and gravel that sometimes can be slippery. The estimated time is 1.5 hours to reach the crater. Overall it’s considered a quite easy trail, but as always, safety is our priority here.
Based on the information above, you would need a proper physical preparation for the hike such as:
- Walking regularly for about 15 minutes a day (for building up endurance)
- Stair climbing exercise (for building up endurance)
- Try breathing exercises or light cardio (e.g. swimming, running, yoga) to boost lung function (sulfuric gas and steep hills are quite challenging for the breathing)
- Get used to early wake-up hours (as it’s required to hike very early in the morning because the trail are open from 2 AM to 12 PM)
If you feel unwell but still want to enjoy Ijen, you could use the “Lamborghini” (trolley service) provided by locals; they’re ready to carry you to the crater and back to the starting point.
