Ejina's desert poplars, the Inner Mongolia forest that Hero turned red

On an October morning in Ejina, the first shuttle bus into the poplar forest fills with tripods before it fills with people. Most of the passengers remember the same few minutes of film: two women in red fighting through a whirl of yellow leaves that turn, mid-stroke, the colour of blood. That sequence from Hero (英雄, Yingxiong), the 2002 wuxia epic, was shot here, along a river at the far western edge of Inner Mongolia, and the trees still turn gold on roughly the same autumn calendar. What has changed is that the forest now has a gate, a boardwalk and a queue. A trip planned around the film goes far better once you know how the place has arranged itself around it.

What the camera borrowed from the river

The trees are huyang (胡杨), the desert poplar, which grows wherever groundwater lies close enough for its roots to reach. In Ejina Banner (额济纳旗), part of Alxa League (阿拉善盟), they follow the Ejin River (额济纳河, Ejina He). Older texts call this river Ruoshui (弱水), the ‘weak water’, as it runs north out of Gansu and thins into the desert.

On screen the forest looks endless. On the ground it is a ribbon, dense in places and patchy in others, with grey gravel plain showing through the trunks on either side. Hero spread its landscapes across several regions, filming desert scenes in Dunhuang and a duel on a lake in Jiuzhaigou, and Ejina supplied only the gold. That was enough to fix the banner in the national imagination. The town of Dalaihob (达来呼布镇), where nearly every visitor sleeps, has built its hotels around those few weeks of colour.

A forest numbered by bridges

The main scenic area, Ejina Huyang Forest (额济纳胡杨林景区), sits on the edge of Dalaihob. It is laid out as a chain of stops named after old river crossings, running from Yidaoqiao (一道桥), the first bridge, to Badaoqiao (八道桥), the eighth. You pay to enter, and in the busiest weeks the scenic area's own shuttle buses carry most of the traffic between stops instead of private cars. Ticket types and shuttle arrangements change from season to season, so check the current ones with the scenic area before you go.

Sidaoqiao (四道桥), the fourth bridge, is the stop that local signs and guides call the Hero forest, Yingxiong Lin (英雄林). Expect it to be the most crowded point of the day, with visitors in rented red capes and long scarves posing among the trunks and selfie poles raised over the boardwalk. Photographers head first for the lower stops, where still pools hold reflections at sunrise. By mid-morning the light has flattened and the tour groups have taken over. Boardwalks and rope lines keep feet off the shallow roots, and staff do ask people to step back onto them.

The grey forest of dead trees

Guaishulin (怪树林), the ‘strange tree forest’, lies a short drive from Dalaihob and shows the other end of the poplar's life. The river pulled back from this ground long ago, and what remains is a stand of dead trunks, silver and split, twisted into shapes that start to look like figures once the sun drops low. In recent seasons it has needed its own ticket, separate from the main forest, and sunset is when the coaches arrive.

Guides here repeat a saying about the tree's endurance that also turns up on souvenir bags and restaurant walls. It is a local motto more than a botanical fact, and it explains why the dead trees are treated as a sight rather than cleared away.

胡杨生而不死一千年，死而不倒一千年，倒而不朽一千年。

Roughly: living, it does not die for a thousand years; dead, it stays standing for a thousand more; fallen, it does not rot for another thousand. The wind at Guaishulin carries fine sand that works into shoes, lens mounts and zips. A scarf over your mouth and a bag that seals will do more for you here than a second lens.

Black City and the lake at first light

Heicheng (黑城), known in Mongolian as Khara-Khoto, is the ruin of a walled town built under the Tangut state of Xixia (西夏) and still lived in during the Yuan period. What survives is a rectangle of rammed-earth walls, half-buried in sand on the windward side, with small white stupas standing along one corner of the rampart. Walkways and signboards show where you can go, and signs ask visitors to stay off the walls themselves.

Juyan Lake (居延海, Juyan Hai), the lake where the river ends, lies north of town, and watching the sunrise there is the banner's daily ritual. Cars leave Dalaihob in the dark, and visitors wait on a boardwalk over reed beds for the sun to come up over flat water, often with gulls feeding in the shallows. In October the temperature before dawn can sit near freezing even after a warm afternoon. The down jacket that felt excessive at lunch earns its place here.

Eating in Dalaihob

Dalaihob is a small grid of streets that feels too big for most of the year and overbooked for a few weeks of autumn. The cooking is Alxa Mongolian with a strong Hui and northwestern accent. Expect hand-held mutton, shoubarou (手把肉), boiled on the bone and eaten with a knife and a dish of salt, and Gansu-style lamb noodles in many small canteens.

Look for shacong (沙葱), the wild sand onion of the Alxa desert, stir-fried with egg or served pickled on the side. It tastes like a sharper chive, and it is the plate locals tend to order for visitors. Breakfast often comes with Mongolian milk tea, naicha (奶茶), salted rather than sweet, with chaomi (炒米), toasted millet, to stir in. Mutton is usually priced by weight, per jin (斤), or half a kilo, so ask for the weight before the cook starts cutting, and expect peak-week menus to differ from the rest of the year.

Getting there and timing the gold

Ejina is a long way from anywhere. The banner has a small airport and a railway station on the line that crosses the desert toward Xinjiang, and both add capacity in autumn. Check flights with the airlines, and trains on 12306, the national rail booking system, as soon as schedules open. By road, you drive north from Jiuquan or Jiayuguan in Gansu across hours of gravel desert, and many visitors fold Ejina into a trip that includes those cities and Dunhuang.

The gold usually peaks between late September and mid-October, depending on the first frosts and how much water is in the river, and a single windy week can strip the branches. The scenic area posts colour updates on its official social accounts through the season, and its opening times shift with sunrise. Confirm both at the gate or with your hotel instead of trusting last year's reports. Ejina sits close to a national border and to restricted areas, so carry your passport on every road out of town and expect checkpoints. Before you book, confirm that your hotel can register foreign guests, because not every property in Dalaihob can.

The mistake to avoid is arriving in the first week of October, the National Day holiday, without a confirmed bed. That week brings the year's largest crowds, room rates climb steeply, and the queue at Sidaoqiao can outlast the morning light. Come a few days earlier or later, on a weekday, and the same trees stand along the same river, with room on the shuttle bus for you and your tripod.
