The enchanting and dangerous "Gate of Hell".

Ijen Volcano 🌋 has the world's most acidic lake. After a 2-hour drive, a 4-hour hike in the rain and mud, and another hour on a rocky path, we were almost the last to leave 😇. Suddenly, a gust of wind tore open a hole for a minute, and a foreign photographer appeared in the clouds. He took pictures of the scenery 🌠 and I took pictures of him. It was like a scene from the end of the movie 25th Hour. I'm still excited about it, like I've found a treasure 🤩. 🎫 Tickets: 100k/person It takes 2 hours to hike to the top of the volcano 👨🏻‍🦯 Or you can take a local rickshaw 💺 (round trip price is 700-1000k/person) ♻️ The bottom of the volcano is a sulfuric acid lake with a pH value of almost 0️⃣ At the top of the mountain, you can see thick white smoke 💨 constantly rising from below ♻️ The air is filled with pungent sulfur smoke Next to it, you can vaguely see sulfur miners working by the sulfuric acid lake without any protective measures ♻️ Their daily task is to mine sulfur from the lake along the stone 🗿 path and carry it away ⚠️ Small tips: ✅ The guide will provide a gas mask, but it is not disposable ⚠️ If you mind, you can buy one in advance and bring it with you ✅ Don't worry about getting lost while hiking 😇 There are many tourists visiting along the way, just follow the crowd to the top of the mountain ✅ You can also bring a headlamp 💡 so you don't have to worry about not being able to see the road ✅ We usually exercise, so we feel okay walking all the way. But going down the mountain is a bit hard on the knees [!][!] To protect your knees, you can also take a rickshaw down ✅ Although it can get hot while hiking, the wind at the top of the mountain 🌋 is a bit cool in the early morning. After sweating from exercise, a jacket is necessary
