You can drink water from the river Slyudyanka even without boiling. After the first half of the trail, there will be no source of water until you reach meteostation.
No equipment needed, but it's good to have proper hiking shoes. If you have trekking poles, take it, especially if you carry a heavy backpack.
There are no shopson the trail, however there is a small "cafe" on the trail.
There are many places where you can set up a tent for free. If you want to set up a camp as close to the top as possible, you can stay at the meteo station of in a camping beside. The camping has a page on Vkontakte social network, so you can book a place or ask any questions.
Most part of the trail is rather easy, the steep ascent begins only at the very top. For a trained tourist it usually takes 6 hours to the top and 5 hours back, thus it's possible to make the whole trip one-day. But for most of the people we recommend to make an overnight stay and spend some time relaxing and enjoying the picturesque landscapes of Chamar-Daban mountain range.
First, you have to walk approximately half an hour from the station Slyudianka-1 to get to the beginning of the trail. There will be several shops along your way, so you can buy some food there. Then, just after the MCHS (Emergency services) base, the trail starts. There is a clear path that is almost impossible to lose. You will cross Slyudianka river several times and then after first 8km of walk there will be a café where you can buy pancakes and tea. Sometimes there is also rice pilaf (Middle-Eastern dish) available. You can stop there for a short break or either spend a night in your own tent or in a guesthouse and have banya in the evening.
After one more hour of walking, the trail goes away from the river, so it's your last chance to get some water before you reach meteostation that's located 1500m above the sea level.
From the meteostation an ascent to the Chersky peak begins. You'll go an ancient Starokomarsky road, which was a part of a tea-road from China to Russia in the 18th century.
