Tian Shan High Route — Kochkor to Kazarman via Kalmak Ashuu Pass and the Suusamyr Valley
Kyrgyz high passes and jailoo silence.
Kalmak Ashuu is the kind of pass that doesn’t show up on most maps and doesn’t care. Starting from Kochkor in the Naryn Region, the route climbs through summer jailoo — the high pastures where Kyrgyz herders still run horses and cattle in the old way — before topping out at 3,446 metres on loose shale switchbacks that only appear to be a road when you’re already committed. The descent into the Kara-Jygach valley toward Kazarman is steep, rutted, and spectacular: vertical canyon walls, no guardrails, and a track width that makes passing another vehicle a philosophical exercise. The Suusamyr Valley floor is flat and fast, but the river crossings feeding into the Kara-Keche basin can run thigh-deep in June snowmelt.
This route is solidly difficult — stock high-clearance isn’t enough on the Kalmak Ashuu ascent after rain. A capable 4WD with lockers and a snatch kit is the floor. Fuel up in Kochkor; there’s nothing between there and Kazarman. No permits required. The window is mid-June through September; the pass closes under snow by October and is impassable until late spring. You’ll share the high route with shepherds on horseback and absolutely nobody else. That’s the point.

Frequently asked questions
Can a lifted Tacoma or stock Land Cruiser handle this route without lockers?
A stock Land Cruiser 70/80 series can manage it in dry conditions, but lockers are strongly advised — the approach to Kalmak Ashuu Pass includes loose shale switchbacks and off-camber shelf road sections where open diffs will leave you spinning. A lifted Tacoma without lockers is a gamble you'll probably regret mid-pass.
When does Kalmak Ashuu Pass actually open and close each year?
Realistically late June through mid-September. Snow can linger on the pass well into June and return early in October — locals and shepherds moving their flocks are the best real-time indicators of whether it's passable. Don't trust calendar dates alone.
Do you need permits or visas to drive this route through the Naryn Region?
Kyrgyzstan is visa-free for most nationalities for up to 30 or 60 days, and this route doesn't pass through any restricted border zones, so no special off-road permit is required. Register with OVIR if you're staying over 30 days — otherwise just a valid passport and vehicle documents.
What's the hardest section and what should I actually expect there?
The climb to Kalmak Ashuu Pass (3,446m / 11,306ft) is the crux — the track is unmarked, eroded in places, and crosses loose rock fields where the line isn't obvious. Expect slow going (2-4 hours for that section alone), possible water crossings on the descent into the Suusamyr Valley, and zero room for mechanical failure with no recovery infrastructure within range.
How much fuel range do I need, and is there any water I can source on the route?
Carry fuel for at least 200km from Kochkor — there are no fuel stops between Kochkor and Kazarman along this route, and Kazarman's supply is unreliable. Water from streams and rivers on the route is generally clean but treat everything; shepherds and their livestock use the same sources upstream.
