If you need a guide for Indonesian volcano waterfalls, this article is all you need

Seeing that everyone is looking for a guide, let me talk about my guide. I found a local guide, who offered a double volcano plus waterfall tour (four days and three nights) for only 1K. The first day after landing in Surabaya, the guide was waiting with a sign right after customs. Our English is not good, but he translated into Chinese for us, telling us some specific precautions and itinerary. Just arrived in Surabaya and didn't have much cash, the guide took us to several ATMs until we withdrew 600w. Later, the guide took us to the homestay hotel we booked next to Sewu Waterfall (with pictures). We hadn't paid the guide fee yet, and it was agreed to pay in two installments. The first installment was 600w. We didn't have that much, and if we gave it all, we wouldn't have money for food. The guide then lent us 100w. The next morning, after breakfast (included), we set out around 8 am. The four of us had two guides arranged for Sewu Waterfall. They accompanied us the whole time and helped us take photos, which was really nice. We played until 11 am and returned to the hotel. After showering, the guide took us to a local restaurant for lunch and prepared to go to the hotel at the foot of Mount Bromo. We arrived in the evening. The third day, we set out at midnight in a jeep arranged to watch the sunrise (also with two guides, one driving and one accompanying us). It's advised to be prepared for the cold (we had already reached the viewing platform when one of our friends said she was cold, so the guide accompanied her down the mountain to rent a down jacket). After watching the sunrise, we took the jeep to the foot of Mount Bromo. Along the way, we stopped for breakfast (since it was included in the cost, the guide found a restaurant for us to order on our own, and he paid for it, the food was quite good). Later, we headed to the homestay at Mount Ijen (very characteristic). The fourth day, we set out at midnight to see the blue fire (with goggles and gas masks). The guide was with us the whole time, accompanying us on the climb... After completing the climb, we went back to the hotel to pack our luggage and the guide took us to the port for Bali. He thoughtfully bought our tickets in advance and even contacted his friend in Bali to wait for us at the port, to take us to Lovina...
