Usually not reliably — Song-Kul sits at over 3,000m, and snow typically closes the access road and the seasonal yurt camps by late September to early October, though the exact date varies year to year with the weather.
If you're planning an October visit, treat Song-Kul as unlikely rather than guaranteed. Message us with your exact dates before booking — we track current road and camp conditions with our partners on the ground.
Jeti-Oguz (including the overnight yurt stay, at a lower altitude with camps that run later into the season), Altyn Arashan's hot springs, and Karakol city tours are all typically still accessible in October, giving you a mountain and yurt-camp experience even after Song-Kul closes.
