Something about the valley makes people want to send messages upward. On the main street in Shifen, and at spots along the Pingxi Line railway, people ink their wishes onto paper lanterns and release them into the air above the Keelung River valley. The lanterns rise slowly — they are not in a hurry — and drift above the forested ridges until the flame inside cools and they settle somewhere on the hillside. It is a practice that draws visitors from across Taiwan and beyond, and it works partly because this is a valley that earned its quietness. Pingxi spent its first decades underground.
Pingxi was an important coal mining town in the early twentieth century — a designation that shaped everything: the railway that penetrated the valley, the old streets that served mining families, the pace of life that extraction demanded. The district sits in the upper reaches of the Keelung River valley, one of the most deeply folded sections of the mountains north of Taipei. Getting coal out required infrastructure, and getting infrastructure in required investment: the Pingxi Line was completed in 1921 precisely to serve the mining economy. The miners who worked these seams built communities at Jingtong, Shifen, and Pingxi itself — communities with temples, opera stages, and shophouses that still stand. Honoring that labor means recognizing that the picturesque old streets were not built for visitors. They were built for working people living working lives in a mountain valley.
The Pingxi Line is the district's lifeline. From Taipei Main Station, a Yilan-bound train takes passengers northeast to Ruifang, where a transfer onto the branch line begins the final leg into the valley. The branch winds up through Sandiaoling and into increasingly forested terrain before the valley stations appear: Dahua, Shifen, Wanggu, Lingjiao, Pingxi, Jingtong. Travel between them is easy — trains run regularly — and the distances are short enough that a visitor can spend a day disembarking, exploring on foot, and catching the next service. Shifen Old Street is the most accessible introduction, with lantern shops and food vendors along a lane where the train track runs so close that pedestrians step aside when a train passes. Jingtong at the end of the line is quieter, its old wooden main street preserved partly by its distance from the more visited stations.
Releases happen year-round in Pingxi, but the Lantern Festival — in January or February, depending on the lunar calendar — transforms the district entirely. During the Pingxi International Sky Lantern Festival, lanterns rise in mass releases that light the valley sky in ways photographs fail to fully capture: the scale, the slow drift, the heat reaching down from hundreds of ascending paper flames. The tradition has grown significantly as tourism to the area has increased, making Pingxi's sky lanterns one of Taiwan's most recognized visual symbols. Visitors write their wishes or names on the lantern paper before lighting the fuel cell inside; the writing burns with the flame, dispersed somewhere in the dark above the valley. It is a ceremony that the mountain landscape makes possible — the enclosed valley creates a column of rising warm air that the lanterns follow upward.
The district's terrain generates waterfalls wherever the rivers drop over the edge of their cut valleys. Shifen Waterfall, accessible by a short trail from Shifen Station, is the widest in Taiwan — a broad curtain of water dropping over a sedimentary ledge in a crescent shape sometimes compared to a smaller Niagara. Lingjiao Waterfall, reached by a different trail, is taller and narrower, more dramatic in its vertical drop. The hiking network around these falls connects the valley communities without requiring any technical climbing, making the trails accessible to visitors who arrive by train. Above the falls, the ridgelines are forested and largely undeveloped — the protected status of the Northeast Coast and Yilan National Scenic Area keeps the surrounding mountains from the kind of development that has transformed lower-elevation terrain around Taipei.
Few places in Taiwan hold their industrial past and their tourist present in such direct tension. In Pingxi, the Jingtong Coal Memorial Park and the Mining Industry Museum stand within walking distance of lantern shops and tea houses. The old streets run between mining-era buildings repurposed for visitors without being fundamentally altered. The railway that hauls day-trippers through the valley is the same railway that hauled coal. This layering is the district's most distinctive quality — not a heritage theme park but a lived geography where the uses have changed but the structures have not. The valley holds its history in plain sight, and the lanterns that rise above it each festival season are as new as the tradition is, drifting above a landscape shaped by work done generations earlier.
Pingxi sits at approximately 25.030°N, 121.760°E in the mountain interior of northeast Taiwan, in the upper Keelung River valley. Flying east from Taipei Songshan Airport (RCSS) at 3,000 feet, the ridge system northeast of Taipei guides the eye toward the valley corridor — look for the river threading between forested slopes. The Pingxi Line can be traced along the valley floor; Shifen Waterfall appears as a white cascade on the south valley wall above the station. During Lantern Festival events, the rising lanterns may be visible from the air as clusters of moving light ascending from the valley. Nearest major airport: Taipei Songshan (RCSS), approximately 29 kilometers to the west.
