Where to start:
Get off at Quarry Bay MTR station and take exit A. Turn right, and you will find yourself walking along the King’s Road towards the direction of Tai Koo Shing, passing the Tong Chong Street and Pan Hoi Street. After about 5 minute’s walk, you will see a flyover, under which there is a road called Mt Parker Road, leading uphill.
Arriving Sam Mun Tsai in Tai Po, follow the sign for the Ma Shi Chau Special Area. After Sam Mun Tsai Village, make your way up a small hill for Ma Shi Chau. This approach takes about half an hour.
To preserve rock formations and rich minerals, Ma Shi Chau was designated a Special Area in 1999, along with nearby Yeung Chau, Centre Island (A Chau) and an unnamed islet. This Nature Trail runs along the rocky shores of the island and presents many types of rocks and landforms. Some parts of the trail are submerged at high tide, so check the tide times before setting off.
The sedimentary rock on the southeastern shore of Ma Shi Chau was formed approximately 280 million to 225 million years ago in the Permian Period of the geological time scale, a period much earlier than the Jurassic Period when dinosaurs roamed the Earth.
A walk on the island of Ma Shi Chau is a journey back to prehistoric times. Along the way there are interesting quartz porphyry, intriguing geological features like Lung Lok Shui, dykes, wave-cut platforms and foldings, as well as coastal flora. As this is a one-way route so you have to trace your steps back to the starting point.
From HK Walkers:
Lying in the north western corner of Plover Cove Reservoir, Bride's Pool Nature Trail is a route that introduces local wildlife and flora. At the Bride's Pool bus terminus, the green-roofed Lion Pavilion welcomes you. Follow the path by the pavilion, there are sweet sounds of birds and rippling stream to keep you company.
A little way ahead the trail crosses over the top of Bride's Pool. Gazing down, silvery falls plunge mightily down the rock face. Legend has it that a bride passed by this treacherous part on her way to the wedding. In bad weather, the wedding sedan chair fell into the pool and she was washed down the waterfall. In memories of this ill-fated bride who got drown there, the pool was named Bride's Pool.
Up ahead on the river bed you find pot-holes carved by swirling sand and gravels which are washed down by water seeping through rock joints. This nature trail passes by the Bride's Pool Stone Bridge, which was built in 1906 by local villagers to provide a link between Wu Kau Tang and Chung Mei Village. After the bridge, back to Bride's Pool Road and comes to an end.
The beginning section of Tai Tan Country Trail is in parallel with Hau Tong Kai, before arriving at Tai Tan Village. This bucolic hamlet is rimmed by coastal mangals where the nearby mudflats are home to mudskippers and fiddler crabs.
The path skirts along the coast, unveiling beautiful scenery of Tai Tan Channel, Ko Lau Wan and Tap Mun across the bay. At Nam Fung Wan, hikers can take a detour on the right to Wan Tsai Peninsula. The promontory was a borrow area in early 1980s. Afterwards, with large scale reforestation programme to repair the damaged landscape, and Sai Kung West Country Park Wan Tsai Extension was designated in 1996, the peninsula now boasts rich vegetation and a modern campsite for large group events.
If you take the coastal path on the left via Lan Lo Au, there is a spectacular view of Hoi Ha Wan. A sheltered and unpolluted bay, Hoi Ha Wan Marine Park provides perfect habitats for marine animals such as corals, coral reef fishes, star fish and jelly fish.
The trail passes an abandoned lime kiln before entering Hoi Ha Village. This kiln is a famous relic showing early industry of lime production with oyster shells or coral skeletons since 1800s.
Take green minibus at Sai Kung to Hoi Ha Road and get off near Hau Tong Kai.

From the official HKWalkers site:
Section One skirts the south side of High Island Reservoir, in Sai Kung East Country Park (4,477 hectares). This is a pleasant beginning, as here the Trail is often flat -- and the few climbs are only gradual.
Section 1 starts at Pak Tam Chung. Take bus 94 from Sai Kung Town and get off at the Pak Tam Chung Terminus adjacent to the Pak Tam Chung Barrier Gate. The starting point by the junction of Pak Tam Road and Man Yee Road is about 400 m from the Barrier Gate.

This is one of the most famous short hikes in Hong Kong, selected by Times as the best hike in Asia.
Roz has the best info:
Start: I usually walk this backwards, starting at Chai Wan (and missing out the last part to Big Wave Bay).
Easier Start: Alternatively, take a taxi from Chai Wan MTR to the Tai Tam Gap Correctional Institute on Shek O road (about HK$20) and miss out the first hill.
End: Ends on the Shek O road. You can catch a bus back to central or take minibus to Shek O for a meal at the Thai (or one of the many other restaurants there) and get a bus or minibus back to Central from there
Time: 2.5 hours
Difficulty: A good walk for beginners. Steep hill up through cemetery (which you can miss out if you get a taxi to the prison instead), and then nice gently undulating walk looking down over Shek O. At weekends you can often see people paragliding and flying model aeroplanes and kites off the steep hills.
Walk out of Chai Wan MTR exit A and up through cemetery. (not particularly well signposted, you may need to ask a friendly grave-digger - basically find the steps that take you up, up, up (see photos below.)
From Anna Tam:
How to get there:Get off at Tsuen Wan MTR station, exit A4. Walk through the covered corridor leading to Discovery Park residential complex, all the way to Castle Peak Road. Carry forward and pass by Tsuen Tak Garden, and you will see Adventist Hospital in front. Opposite the hospital you can find a staircase with a sign indicating it is the Yuen Tsuen Ancient Trail. The starting part is hard, as it is up and up and up. But once it is over, you will have pleasant walks ahead.
Though only 2.3 km long, the Lung Ha Wan Country Trail makes for a fairly tough hike, especially on a hot sunny day (there is no shade en route). But it’s also a rewarding hike, with splendid views over grassy hillsides dotted with boulders, as well as Sai Kung hills, and islands including the jagged Ninepins.
The route is simple: a steep climb from Tai Hang Tun, before the trail eases to pass over the 291-metre summit of Tai Leng Tung, then down to Lung Ha Wan: if the trail’s wet, it might be slippery in places here.
Getting There (source):
There is no public transport to the starting point at Tai Hang Tun barbecue site at the end of Clearwater Bay Road. Take one of the following buses that pass by or end at Tai Au Mun, then walk about 15 minutes to the trail's start: KMB No. 91 from Plaza Hollywood in Choi Hung (Diamond Hill) or green minibus 103M from Tseung Kwan O MTR Station towards Clear Water Bay Second Beach; green minibus 103 from Kwun Tong Ferry Pier to Tai Au Mun; or green minibus 16 from Po Lam, Tseung Kwan O to Po Toi O.
