The owner and his partner are very friendly at Osing Inn. The room is very clean yet basic with a fan and free coffee/water/tea is welcome, you will appreciate it. There is a warung on walking distance if you want dinner. The shower and toilets are clean and what you expect at this price.
Beware, the tour starts around midnight and you will be back at 8:30AM. I did it without sleep and felt disoriented - my own fault of course. Gas masks and lights were of good quality, they also provide one water bottle and plastic rain cape when it rained, and goggles to protect your eyes
The hike goes as following: a few hours going up the vulcano, sometimes pretty steep (locals even offer rides with carts if you're too weak), you descend the crater for an hour (slippery when wet, give way to the mine workers and don't fall off the path), stay around 30min down where you can see the blue fire (I didn't see it, maybe because of the rain I guess) and there's a lot of fumes from the pipes they put there, go back up the crater for an hour, see sunriss (it was cloudy/misty, couldn't see the lake until it cleared up a tiny bit for 5 minutes), bit disappointed but I knew I was visiting in bad weather conditions and took prace with it.
Yes, this activity is not 100% safe. The sulphur smoke can catch your breath, I even read reviews on a blog about someone panicking which I could understand. People cough, eyes are a bit irritated, the path down to the crater is dangerous yet doable. I liked the experience even though I didn't see the lake perfectly and no blue fire. It opened up my eyes what the people of Banyuwangi are doing in the mines. Please respect them, buy their souvenirs and see it as a donation...
Recommend going there! But please don't bring your kid (there was an 11 year old boy in my group) and know you're on your own risk because your guide passes 3 warning signs that tourists shouldn't go down the crater.
