Hi, i will visit Kyrgyzstan and i want to know is there a way to reach Inylchek glacier by feet with a budget less than 500 euros. If not, do you recommend other beautiful treks in country in reosanble prices.Thank you

If you go without an agency (recommended !) then trekking is almost free in Kirgyzstan.
Inylchek glacier is in a very remote area, so it is difficult to reach. If, as you username allows me to suspect, you speak russian, then ask the russian mountaineering association for information, they have all the maps and topoguides.
Failing that, Ala Archa national park is close to Bichkek and you can spend 3 days trekking there. If you like being alone, try to reach the Adygene lake.
Treks around Karakol are beautiful also, try to see Ala-kul lake.
Maps can be bought in Bichkek, name of the shop : GeoID. It is on Kievskaia street, behing the black rabbit restaurant.
