Yiwu County: Self-Driving Hami’s Northern Backcountry
North of Hami city, where the Tian Shan rises and the road thins, sits Yiwu County — a windswept backcountry most travelers never reach because the highway west is faster and the brochures point elsewhere. I turned north on a whim and found the oldest trees and one of the strangest lakes in Xinjiang, plus a silence that the famous routes have lost.
Yiwu (ee-woo) is a county in the Hami prefecture, roughly 170 km north of Hami city up the S302, tucked against the mountains that separate Xinjiang from the Gobi. It is remote, windy, and quietly spectacular. The Hami guide treats the city as the region’s whole story; Yiwu is the chapter after the last page.
The drive north
From Hami city, take the S302 north. The road climbs through a canyon, over a high pass, and down into Yiwu’s green basin, a run of about three hours. The pass is exposed and frequently windy — I cover the behaviour in my strong-wind zones guide — and on my crossing a gust actually pushed the car toward the verge before I slowed. Grip the wheel, drop your speed, and let the trucks set the pace.
The poplar forest
Yiwu’s desert poplars are the headline. Unlike the tidy groves at the famous reserves, this forest holds trees estimated at several hundred to over a thousand years old — squat, gnarled, silver-trunked survivors that have held the sand since before the Silk Road had a name. In October they turn a deep, metallic gold, and standing among them is like walking through a cathedral built by weather. I spent an hour with no one else in sight, listening to the wind move through trunks that have heard it for a millennium.
The forest has a small entry and a boardwalk now, but it is nothing like the crowded southern reserves. Go early; by mid-morning the light flattens and the tour vans arrive.
The color-changing lake
A few kilometres from the forest sits Huan Cai Lake — a salt lake that shifts colour with the light and the weather, from blue to pink to a flat mirror grey. Locals call it the “magic-color lake,” and on a still evening it lives up to the name. I arrived at dusk and watched it turn from steel blue to a faint rose as the sun dropped behind the mountains. No boats, no fee, just a dirt pull-off and a view that rearranges itself by the minute.
Why the edges matter
The Barkol grassland gets the tour buses of the north; Yiwu gets the weather and the old trees. For a self-driver who has done the headline routes, this is the reward for turning where the map goes quiet — a forest older than the roads and a lake that paints itself. I came back down the pass that evening convinced it was the best unplanned stop of my Hami loop.
The wind and the dunes
Yiwu is one of the windiest corners of Xinjiang, and the locals have built their lives around it — windbreak forests, weighted roofs, and a wry pride in the gusts that close the pass for days in winter. There is also a singing sand dune on the basin’s edge, a lone hill of fine sand that hums when the wind runs over it, climbable for a view back across the poplars. I climbed it on a calm morning and heard nothing but my own breathing; a local later told me the song needs the wind behind it, which is fair.
The wind is the real attraction and the real hazard. Check the forecast before the northern crossing; a strong-wind day is not the day to learn the S302.
Food and the melon
Yiwu shares the Hami melon fame of its bigger neighbour — the sandy soil grows a small, intensely sweet melon that appears at roadside stalls in July and August. I bought a wedge for 3 yuan and ate it leaning on the car, the wind trying to take the rind. The county town has the usual noodle and kebab spread; eat there before you head into the forest, because the sights have nothing but the occasional herder’s dairy stand.
Carry water and a snack. The forest and lake are outside town, and the small stalls keep short hours.
When to go
October is the poplar month — the gold is at its peak and the light is long. Spring (April–May) is mild and green. Summer is hot and windy; winter closes the pass with snow and ice, and I would not cross then without the preparation in my winter tires guide. The lake is best at dusk year-round, when the colour shift is most dramatic.
Practical notes for the self-driver
– Fuel in Hami city before you climb, and again if Yiwu town has a station open. The in-between is empty.
– The S302 pass is exposed and camera-free but unforgiving. Slow down in gusts; the trucks know the road, follow their lead.
– Carry cash. The town ATM was intermittent on my visit, and the forest entry took notes.
– Tell someone your route. Signal is gone for long stretches north of the pass, and a breakdown out here is a long walk in the wind.
– Respect the old trees. Stay on the boardwalk; the ancient poplars are fragile and irreplaceable, and the forest rangers are earnest about it.
The road to the edge
Hami is usually the place travelers pass through. Yiwu is the reason to slow down on the way. Drive north over the windy pass, walk among trees older than the roads, watch a salt lake paint itself at dusk, and come back down with a story the highway crowd never hears. The Hami guide will get you to the city; Yiwu is what makes the north worth the detour. I have sent a few people up that road, and every one came back with the same report: the old trees, and the wind, and the lake that would not sit still.
The forest boardwalk, in detail
The Yiwu poplar reserve has built a boardwalk and a viewing loop since my first visit, and it is worth taking slowly. The path runs among the oldest trees — squat, silver-trunked survivors with branches like broken arms, each one a small monument to surviving the basin’s drought for a millennium. Plaques give rough ages; the oldest I saw was listed at over nine hundred years, which is a sobering thing to stand beside. In October the leaves are a deep metallic gold and the boardwalk fills with photographers at midday, so I went at the open hour and had the old trees to myself for the first hour.
The lake that paints itself
Huan Cai Lake is a salt lake, and salt lakes shift colour with the light, the mineral concentration, and the weather — blue under a clear sky, pinkish when the algae respond to heat, a flat steel grey when clouded. I sat on the dirt pull-off for an hour at dusk and watched it move through three shades without the wind changing. There is no entry, no boat, no fee; just a place to stop and watch water that will not sit still. Locals call it the magic-colour lake, and on a still evening it earns the name.
The wind, closer
Yiwu’s wind is not a metaphor; it is the defining fact of the place, and the county has built windbreak forests and weighted its roofs against it. On the S302 the gusts come in waves, and a high-sided vehicle gets shoved — I learned this in a rented SUV that leaned like a sailboat and needed a firm two-handed correction. The wind-zones guide explains the technique; the discipline is to slow before the gust, not during it. On a calm day Yiwu is gentle; on a wind day it is a lesson in humility, and the lesson is worth heeding before you commit to the pass.
Costs and timing
The forest has a modest entry now — a few dozen yuan — and the lake is free. Fuel in Hami city before the climb; Yiwu town may have a station but do not count on it. A half-day — forest, lake, back — costs under 150 yuan beyond fuel. October is the month; spring is the gentle alternative; summer is hot and windy; winter closes the pass. I would not cross in winter without the preparation in my winter tires guide.
The edge of the map
Hami is the gateway; Yiwu is what lies beyond it when you turn north instead of west. The old trees, the colour-shifting lake, and the wind that closes the pass are the reasons to make that turn. The Hami guide will get you to the city; Yiwu is the detour that makes the north worth the drive, and the one I describe first when friends ask where the quiet corners went.
The forest deserves more than a boardwalk glance. I went in once with a herder who showed me the oldest tree he knew — a silver giant he said his grandfather had sat beneath, and his grandfather before that — and told me, through a teenager’s translating, that the forest was “the old man of the basin” and deserved respect. We did not climb on the roots. That framing — the trees as elders — stuck with me more than any plaque, and I have walked the boardwalk since with more care than I arrived with.
The S302 is the real attraction and the real hazard. On a calm day it is a lovely high drive; on a wind day it is a white-knuckle run with the gusts shoving a high-sided vehicle toward the verge. I check the forecast before I commit and have turned back at Hami when a wind warning came through by mid-morning — boring, safe, and the right call. The wind-zones guide has the technique; the discipline to use it is mine.
Yiwu’s melon, by the way, is the sweetest I ate in Xinjiang — smaller and denser than the famous Hami type, with a texture closer to honey. A roadside stall sold me a wedge for 3 yuan and refused the extra; the grandmother running it simply pointed at the sky and said “sun” as if that explained everything, which it rather did. I bought two more for the road and ate them across the pass, the sweetness a small compensation for the wind.
For the lake, stay until dusk. The colour shift is the whole point, and a midday visit misses it. I have sat at Huan Cai Lake through three shade changes and would do it again; the salt flat is never the same colour twice, and the patience is the price of admission. Costs stay low — forest entry a few dozen yuan, lake free, fuel in Hami — and the reward is a corner of Xinjiang most drivers never turn toward.
