It’s hard to believe that Sanmin Bat Cave (三民蝙蝠洞), hidden in the wooded hills off the North Cross-island Highway in Taoyuan City, was only “discovered” in 1923. The cave, 50-meters long, 30-meters in height and 20-meters in depth, is one of Taiwan’s largest. In fact, as far as I know only the Thousand People Cave (千人洞), hidden in a far more remote location high in the rugged mountains of Chiayi County, is bigger.
These days the Bat Cave is one of Taoyuan’s better-known natural wonders, so it’s surprising, perhaps, that until about a decade ago getting to the cave was a bit of an expedition.
Then, as now, a trip to this mysterious, yawning overhang in a rocky cliff (like most examples in Taiwan, it’s not really a true cave) started by following the first few kilometers of the North Cross-island Highway (Highway 7) from the town of Dasi (大溪) to the smaller settlement of Sanmin (三民). The highway forms the main street of this little village, which seems to have been trapped in a time warp, and, unlike nearly Fusing (復興), has changed little in decades.

Immediately after crossing a bridge over a stream in the middle of the village, turn left down a signposted lane, passing a church (a reminder that this is Aboriginal country — the Atayal people live in the area).
In exactly three kilometers, the road ends at a parking area: the trailhead for the Bat Cave. Four hundred meters before the car park, a short detour down a road on the left leads to Jiguopai Old Church (基國派老教堂), a small stone chapel, standing in a grassy field and looking for all the world as though it were airlifted in from somewhere in northern Europe. It’s become quite famous in recent years, and attracts a steady stream of visitors.
Until the authorities greatly improved access to the Bat Cave about a decade ago, this was where the fun started, as a narrow track infested with head-high silver grass connected with the top of a fixed rope, an essential aid for negotiating a long, steep and slippery rock face, and getting safely down to the bottom of the gorge below the Bat Cave.

Safely at the bottom, visitors next faced a short but slippery river trace upstream. A large rock, which blocks further progress, required scaling another fixed rope, and a little further upstream the huge mouth of the cave finally loomed in front.
This short but exciting adventure was one of the highlights of a visit to Sanmin Bat Cave, so it’s sad to say the route is no more. Local authorities have created a new route, cutting a stepped path down into the gorge and engineering a wide trail, high and dry above the stream, up to the cave. The resulting experience is less memorable, but it’s still a fascinating and atmospheric place, especially during weekdays (it can get busy on weekend afternoons).
A wooden arch beside the parking area at the end of the road marks the beginning of the new path — a wide, brick-paved track, studded at intervals with tiles painted with spooky black bats. It’s a short uphill climb to a junction next to a small viewing tower. Take the left fork here, and stone steps descend gently into the wooded depths of the gorge just below the Bat Cave. Cross the stream and follow the wide, surfaced path for a minute or two. Climb a series of steps around a large boulder, and the Bat Cave itself suddenly comes impressively into view.

The great overhang lies in a beautiful, sylvan glen hung with ferns and grass, echoing with the sound of a small waterfall which pours into the ravine beside the cave. It’s an impressive sight, even though the bats that once called it home have long-since been scared off by the increasing number of visitors. Try to arrive around the middle of the day, when the sunlight briefly streams into the usually gloomy gorge.
Beside the great overhang lies a smaller but fascinating natural curiosity. The 15-meter-high waterfall that plunges into the gorge beside the cave has worn a small but beautifully formed natural hole through the solid rock. If you follow the brick road straight ahead at the junction next to the viewing tower above the Bat Cave, it soon ends at a dirt path that leads to a second natural cave a couple of kilometers (40 minutes’ walk) to the east: Guanyin Cave (觀音洞). Look out on the left just after the beginning for a side trail that leads down to the brink of the waterfall beside the Bat Cave for an unusual view over it (but beware the very slippery mossy rocks in the streambed).
For years, the path to Guanyin Cave was spared the excesses of the well-meaning but sometimes ecologically insensitive local authorities, and was a beautiful short walk beside two mossy streams, passing a pretty waterfall. Unfortunately, work began last month on “improving” the path, and the natural beauty of the trail is already being compromised. At the end is a gate on the edge of the compound of the large temple built in front of Guanyin Cave. The huge temple building itself is functional rather than decorative, but behind it, dominating the view and visible for miles around, is a huge, gleaming gold statue of the seated Guanyin, which is an impressive sight.

Jan. 5 to Jan. 11 Of the more than 3,000km of sugar railway that once criss-crossed central and southern Taiwan, just 16.1km remain in operation today. By the time Dafydd Fell began photographing the network in earnest in 1994, it was already well past its heyday. The system had been significantly cut back, leaving behind abandoned stations, rusting rolling stock and crumbling facilities. This reduction continued during the five years of his documentation, adding urgency to his task. As passenger services had already ceased by then, Fell had to wait for the sugarcane harvest season each year, which typically ran from
It’s a good thing that 2025 is over. Yes, I fully expect we will look back on the year with nostalgia, once we have experienced this year and 2027. Traditionally at New Years much discourse is devoted to discussing what happened the previous year. Let’s have a look at what didn’t happen. Many bad things did not happen. The People’s Republic of China (PRC) did not attack Taiwan. We didn’t have a massive, destructive earthquake or drought. We didn’t have a major human pandemic. No widespread unemployment or other destructive social events. Nothing serious was done about Taiwan’s swelling birth rate catastrophe.
Words of the Year are not just interesting, they are telling. They are language and attitude barometers that measure what a country sees as important. The trending vocabulary around AI last year reveals a stark divergence in what each society notices and responds to the technological shift. For the Anglosphere it’s fatigue. For China it’s ambition. For Taiwan, it’s pragmatic vigilance. In Taiwan’s annual “representative character” vote, “recall” (罷) took the top spot with over 15,000 votes, followed closely by “scam” (詐). While “recall” speaks to the island’s partisan deadlock — a year defined by legislative recall campaigns and a public exhausted
In the 2010s, the Communist Party of China (CCP) began cracking down on Christian churches. Media reports said at the time that various versions of Protestant Christianity were likely the fastest growing religions in the People’s Republic of China (PRC). The crackdown was part of a campaign that in turn was part of a larger movement to bring religion under party control. For the Protestant churches, “the government’s aim has been to force all churches into the state-controlled organization,” according to a 2023 article in Christianity Today. That piece was centered on Wang Yi (王怡), the fiery, charismatic pastor of the
