Tai Mo Shan Hike: The Easy Road Route, the Ng Tung Chai Waterfalls Way & Frost Season

The Tai Mo Shan hike takes you to the top of Hong Kong at 957 metres, and the surprise is that the easy version is genuinely easy. A KMB bus drops you at 470 metres on Route Twisk, and from there most of the climb is a paved road. The hard version starts at the bottom in Ng Tung Chai, climbs past the highest waterfall in the city, and gains almost 900 metres. I have done both. This guide covers the two routes, the buses and fares, what the top actually looks like, and the few winter days each year when half of Hong Kong goes up to look for frost.

Tai Mo Shan at a glance

• Height: 957 metres, the highest point in Hong Kong. Lantau Peak (934 m) and Sunset Peak (869 m) are second and third.
• Name: Big Hat Mountain.
• Easy route: bus 51 to the Tai Mo Shan Country Park stop, then Tai Mo Shan Road to the top. The tourism board lists it as about 5 km, about 2 hours up and 4 hours return, moderate. Sassy Hong Kong rates the same route easy at about 1.5 hours.
• Hard route: bus 64K to Ng Tung Chai, up past the waterfalls, over the top and down to the Visitor Centre. Journey Era logged 10.37 km, 895 m of climbing and 2 hours 40 minutes of moving time.
• The actual summit: off limits. The Observatory's weather radar station sits on it, so you finish on the road just below.
• Best season: late autumn to winter for clear air. Spring and summer are the cloud months.

The easy way: bus 51 and the road

Take the MTR to Tsuen Wan and catch KMB bus 51. It starts at the Nina Tower terminus by Tsuen Wan West station but also stops outside Tsuen Wan MTR station, which is where I board. The full fare is HK$10.2, the whole run to Sheung Tsuen is timed at 28 minutes, and you want the stop called Tai Mo Shan Country Park, at Tsuen Kam Au on Route Twisk. You are already at about 470 metres, which is why Sassy calls this "halfway there" before you have taken a step.

Walk about five minutes along Tai Mo Shan Road to the Visitor Centre (open 9:30am to 4:30pm, closed Tuesdays except public holidays and the first two days of Chinese New Year). Around it are toilets, a campsite, about 60 barbecue stoves and a small refreshment kiosk, which is the last place to buy anything. Fill your bottles here.

From there the route is simply the road. There is a set of fairly steep steps early on, then the paved road switchbacks up through open hillside with the view widening at every bend over the reservoirs and hills of the New Territories, with almost no city in frame. The road ends at the radar station's boundary. That is the top for visitors, and there is no marked viewpoint, so people spread out along the roadside rocks. Come back down the same way for the bus, or drop down the Ng Tung Chai side to make a loop if you have the legs.

If you want the mountain without the climb, a taxi or car can get you to the Visitor Centre car park, but everything above it is still on foot.

The hard way: Ng Tung Chai waterfalls to the top

This is the route to pick if you want a proper hike rather than a road walk. Get to Tai Po Market station on the East Rail Line (or Kam Sheung Road on the Tuen Ma Line) and take KMB bus 64K, which runs between Tai Po Market and Yuen Long West for a full fare of HK$9.6. Get off at Ng Tung Chai, walk back about 100 metres and take the signed trail on the opposite side of the road.

The path starts as a paved village lane, passes under an archway and climbs into thick forest. After 30 to 40 minutes you reach the first of the Ng Tung Chai waterfalls. The country park's names for the four are Well Falls, Middle Falls, Long Falls and Straggling-hair Falls; hikers' blogs call them Bottom, Middle, Main and Scatter. Long Falls is 35 metres, the highest drop in Hong Kong. The lowest fall, tucked into a narrow rock slot, was my favourite spot on the whole mountain. The waterfall branch adds only 15 to 20 minutes to the direct trail, so take it.

Stay on the marked trail. There are flash-flood warning signs along the stream for good reason, and the rocks around the falls are slippery even in dry weather. This is a look-but-don't-swim route.

Above the falls the climbing starts in earnest: rocky steps, consistently steep, with still about 500 metres of height to gain. It is well signed and there is no exposure, just a lot of up. The final stretch joins the road near the radar station. Most people then walk down the road to the Visitor Centre and catch bus 51 back to Tsuen Wan. Expect around 5 hours with stops.

Other ways up

MacLehose Trail Stage 8 crosses the mountain from Lead Mine Pass to Route Twisk on a concrete path, which makes it the usual choice for sunrise because you can follow it by torchlight. Stages 7 and 8 together add Needle Hill and Grassy Hill for a three-peak day of around 6 hours from Shing Mun. That is a serious outing. If you are new to hiking here, do the road route or one of the beginner-friendly trails first.

Clouds, silvergrass and the frost days

The one thing that ruins Tai Mo Shan is cloud, and it gets more of it than anywhere else in the city. The top can sit inside a white ball while Tsuen Wan is in sunshine. Spring and summer humidity are the worst for it; a dry, cool winter day is the best bet for the full panorama. Check the Observatory's forecast and, if the top looks murky from the bus, consider the waterfalls route instead, which is mostly in the trees anyway.

From November to January the silvergrass is out. The spot Sassy sends people to is the Wo Tong Kong side trail off Route Twisk, which does not connect to the top, so treat it as a separate short walk. If you have seen the silvergrass on Sunset Peak, you know the look. In February and March the Taiwanese cherry trees by Rotary Park, near the start of the road route, come into bloom.

Then there is frost. Tai Mo Shan is where Hong Kong's sub-zero readings come from: the Observatory's station up here, running since 1997, hit minus 6.0°C in the January 2016 cold wave, and on 23 January 2024 ice formed at minus 2.4°C. Frost is reported in Hong Kong on only one to two days a year on average, so when a cold snap is forecast, crowds head up the mountain before dawn hoping to see it. On that 2024 morning the government closed every lane of Tai Mo Shan Road for safety. My advice: if you want frost, go on foot from the bus stop, very early, with proper layers and a headtorch, and expect company. Rime, the feathery white ice that grows on railings and plants in freezing fog, is rarer still; the Observatory called the December 2010 display "a rare spectacular sight".

Food, water and the dim sum stop

There is nothing to buy above the Visitor Centre kiosk, so carry more water than you think you need and your own lunch. The reward on the way down is Chuen Lung, a village two stops before the park on bus 51, where Duen Kee is an old-school dim sum teahouse (closed Mondays). Going up, I get off at the park; coming down, I get off at Chuen Lung, eat, and catch the next 51 to Tsuen Wan.

Is the Tai Mo Shan hike worth it?

Yes, on a clear day, and especially if you want to stand on top of Hong Kong without a dawn start. It is not the most dramatic hike in the territory: for ridgelines and coast, the routes in our best hikes with a view win, and for a sunrise summit Lantau Peak has the better dawn. What Tai Mo Shan has is scale: on the right morning you look down on a sea of cloud with the New Territories underneath it, and you got there on a HK$10.2 bus.

Quick answers

• Is Tai Mo Shan hard to climb? Not by the road from the bus 51 stop: you start at 470 metres and walk a paved road for most of the rest. The Ng Tung Chai waterfalls route is a different matter, with about 895 metres of steep, stepped climbing.
• How long does it take to hike up Tai Mo Shan? About 1.5 to 2 hours up from the Tai Mo Shan Country Park bus stop, 4 hours return. From Ng Tung Chai over the top to the Visitor Centre, budget around 5 hours with waterfall stops.
• How do I get to Tai Mo Shan from Tsuen Wan? KMB bus 51 from Nina Tower or Tsuen Wan MTR station, HK$10.2, to the Tai Mo Shan Country Park stop on Route Twisk. The Visitor Centre is five minutes further on foot.
• Where is the Tai Mo Shan hike starting point? The Tai Mo Shan Country Park bus stop at Tsuen Kam Au for the road route, or the Ng Tung Chai stop on bus 64K for the waterfalls route.
• What is the most beautiful hike in Hong Kong? I would still give that to Dragon's Back or Lantau Peak at sunrise. Tai Mo Shan wins on scale and on the sea of cloud, not on drama.
• What is the hardest hike in Hong Kong? Not this one. MacLehose Stages 7 and 8 over Needle Hill, Grassy Hill and Tai Mo Shan is a tough 6 hours, but the harder names in the city are Sharp Peak and the Lantau ridges.
