ACCESS TO MT. IJEN VIA BANYUWANGI

Kawah Ijen is closer to Banyuwangi than to Bondowoso, but the road is very steep and has deteriorated badly. A 4WD is essential. If you want to spend the night before climbing to Kawah Ijen, it is most likely you spend the night somewhere between Banyuwangi and Licin instead of at the plantation. But spending two nights at the plantation is really worthwhile if you are interested in the Javanese way of life.
Directions to get to Paltuding and the Ijen crater lake
A minibus from Banyuwangi will take you as far as Licin village. In Licin you can spend the night in Ijen Resto & Guesthouse or in the luxurious Ijen Resort and Villas. From Licin you either charter a 4WD or a motorbike. If you rent a car in Banyuwangi to bring you to Paltuding it will cost you around IDR 650,000 - IDR900,000. By motorbike it will be around IDR 250,000 - IDR 350,000.
Directions to get back to Banyuwangi
At Paltuding you will find some motorbikes that can bring you back or to any other destination that you desire.

By motorbike
If you are a traveler alone (and on a budget), a good and interesting alternative might be to go "all the way" by motorbike to the Ijen crater lake. By motorbike makes you feel part of the Indonesian community while almost nobody will notice you are a foreigner. Negotiate with your driver about the costs, what is included and not and where to spend the night.
