The MacLehose Trail is a hiking trail that crosses much of the New Territories, Hong Kong, starting from Pak Tam Chung, Sai Kung District in the east to Tuen Mun Town, Tuen Mun District in the west. It is the longest trail in Hong Kong and the path is marked by distance posts at 500-metre intervals. The trail is named after Murray MacLehose, Baron MacLehose of Beoch, the longest-serving governor of Hong Kong, who established the Country Parks and was himself an enthusiastic hiker. The trail passes through a variety of natural scenery including beaches and mountains.

The MacLehose Trail starts in Pak Tam Chung, then weaves its way anticlockwise around the Sai Kung peninsula. It then hugs the Sai Kung district border with Sha Tin, until it meets the mountains separating Kowloon and the New Territories. The trail proceeds along the mountain range, culminating in an ascent up to the highest point in Hong Kong, Tai Mo Shan. The trail then winds its way to Tuen Mun in the western end of the New Territories, following a catchwater for much of its last section.

History In the 1970s, the Hong Kong Government, spearheaded by Sir Murray MacLehose, moved to protect Hong Kong's countryside and open it up for recreation. The first step towards the creation of country parks was the approval of a $33 million, five-year plan for "recreational development" in 1972, which included the provisioning of equipment such as picnic tables, litter bins, and barbecue pits. The Director of Agriculture and Fisheries, E. H. "Ted" Nichols, announced in July 1975 that the Government planned on passing legislation to give country parks statutory status. As part of the plan, "Nature Trails" were proposed to "maximize understanding and consequent enjoyment of the countryside". The Country Parks Ordinance was enacted and came into effect in 1976, and the Country Parks Board was formed shortly thereafter. The Department of Agriculture and Fisheries under Nichols "joined up village paths and grass cutters' tracks" to form a trail extending from Mirs Bay to Castle Peak, and Nichols named the trail after MacLehose and his wife, both avid ramblers. After nine months' work, the MacLehose Trail was officially opened on 26 October 1979 by MacLehose and Nichols. The trail opened with 12 campsites along its route, equipped with simple toilet facilities and barbecue pits.

Only days after the opening, the trail was marred by fires that broke out due to the reckless use of joss sticks by grave-sweepers on Chung Yeung Festival. Parts of the Tai Lam Country Park were badly burnt and said to take at least five years to regrow.

The MacLehose Trail was instantly popular with long-distance hikers; multiple attempts were made to complete the 100-kilometer trail in under a day. The first reported sub-24-hour record was achieved on 13 November 1979 by two British Army workmates, who completed the trail in 22 hours 25 minutes. The record was beaten not a month later by eleven locals; the fastest runner having traversed the trail in 18 hours 28 minutes. Numerous attempts have been made since then; the record of 10 hours, 38 minutes, 8 seconds was set by Wong Ho-Chung, one of Hong Kong's best ultramarathon runners, on 4 December 2020.

Isolated incidents of robbery happen infrequently on quieter parts of the trail. Hikers have been advised not to attempt the trail on their own, especially at night. On 23 November 1980, a group of 24 hikers were robbed when three of them were held at knifepoint. In 2018, a mainland Chinese man was sentenced to seven years' imprisonment for serial robbery on hiking paths, including the MacLehose Trail at Ma On Shan. Emergency phones maintained by PCCW are dotted along the trail, and mobile network coverage is good virtually throughout.

The MacLehose Trail celebrated its 40th anniversary on 26 October 2019, with the Agriculture, Fisheries and Conservation Department (AFCD) holding celebratory events in Shing Mun Country Park, through which Sections 6 and 7 run. Events included treetop ropes courses, a hiking challenge up Needle Hill, guided war relic tours, and children's free play activities. Chan Yat-fong, veteran hiking organiser and trailblazer, and Stephen Chu, TV personality and avid hiker, both spoke at a talk organised by the AFCD for the occasion.

Route description The MacLehose Trail is marked by two hundred numbered distance posts at 500-metre intervals, ranging from M001 to M200. Fingerposts and stone pillars mark the trail at junctions with other major hiking routes. In addition to their respective post numbers, distance posts indicate their trail section, grid reference number, and the AFCD website, all information which can assist hikers in communicating their location to relevant authorities in an emergency. The most prominent feature is arguably the distinctive logo for the MacLehose Trail: the silhouette of a young backpacker with one leg on a rock, hands resting on their knee, facing towards the left. The logo was designed by Tong King-sum, a famous local sculptor who once worked as a civil servant in the AFCD. Lord MacLehose commented that the logo "immortalise[d him] as the perpetrator of intense fatigue in exhausted bodies under heavy loads on semi-perpendicular slopes", but others have described it as "aesthetically beautiful". Early stone markers were individually carved by workers, resulting in slightly varied designs of the silhouette.

Easy Moderate Demanding Difficult Very Difficult

Sai Kung Section 1 starts at the junction between Tai Mong Tsai Road and Pak Tam Road, around 500m due northeast from the Pak Tam Chung carpark, bus terminus, and visitor centre. The trail ascends along Tai Mong Tsai Road and continues along Sai Kung Man Yee Road, on the south side of the High Island Reservoir. About 4km from the start, the trail crosses the western dam of the reservoir, providing an expansive view over Kau Sai Chau, Chong Hing Water Sports Centre and Yuet Ming Pavilion. The pavilion was built on what was the High Island Detention Centre, which processed Vietnamese boat people from 1989 to 1998. Continuing onto High Island itself, minor trails branch off towards coastal villages, serving as their only land-based connection to the rest of Sai Kung. One such village is Pak Lap, a Hakka village with more than 300 years of history and home to a small, idyllic campsite. Another village, Tung A, houses one of the oldest surviving Tin Hau temples in Hong Kong. Other villages on the northern shore of High Island were flooded during the construction of the reservoir, displacing four hundred Hakka villagers. The trail leaves High Island onto the East Dam, where visitors are able to view hexagonal columnar jointing of volcanic tuff, an integral part of the UNESCO Global Geopark. Other attractions in the vicinity include the dolosse wall lining the East Dam, a wooden boardwalk overlooking a sea cave, and a sea stack of hexagonal columns at Po Pin Chau. A blue monument in the shape of a dolos stands at the southern end of the dam, commemorating those who died in the construction of the High Island Reservoir. Section 1 ends 800m away from the East Dam near Long Ke, 90m above sea level.

Section 2 starts with a short section along the distinctive Long Ke coastline, which is formed by jagged columns of rhyolite. The trail then takes a steep ascent up Sai Wan Shan (Sai Kung), an exposed route without any shade — the Government Flying Service on one day in September 1999 took off seven times to rescue 17 heatstroke victims from this area. However, at the peak, hikers are rewarded with a clear view over the Sai Kung coastline and of Sharp Peak to the north. Sharp Peak, true to its name, is one of the Three Sharp Peaks of Hong Kong, known for its difficulty from steepness and remoteness. The trail gradually snakes down to a crossroads at Chui Tung Au. A clear, concreted-over path here leads to Sai Kung Sai Wan Road, where private minibus services are available. Veering right at Chui Tung Au, the main trail reaches sea level at Sai Wan Beach, a popular campsite with toilet facilities and small stores. Visitors are able to enjoy panoramic views over Sai Wan and the two outcropping islands of Tai Chau and Tsim Chau; campers in particular have unobstructed visibility of the sunrise over the South China Sea. Leaving Sai Wan Beach, the trail weaves along the coastline of Tai Long Wan until it reaches Ham Tin, a small fishing village. The trail climbs a small hill to reach Tai Long Au and crosses the Sai Kung/Tai Po administrative border, before descending westwards to sea level at Chek Keng, where kai-to services to Wong Shek and Wan Tsai are available. This is followed by a gradual ascent towards Pak Tam Au, where Section 2 ends. Public transport, toilet facilities, and a water refilling station are available here.

Section 3 leaves Pak Tam Road to enter the Sai Kung West Country Park. Hikers are immediately faced with a steep ascent up Ngau Yee Shek Shan, 425m above sea level. Section 3 is often said to be one of the toughest parts of the MacLehose Trail, due to its "undulating mountains" and "steep gradients"— however, hikers are rewarded with an unobstructed view over Tolo Harbour, Tai Po, and Ma On Shan throughout the first half of the Section. The trail continues westwards along the side of Ngam Tau Shan, descending gently towards Cheung Sheung plateau. This area once housed multiple villages in the 1960s, but many villagers have moved away since the industrialisation of Hong Kong during the 1970s. The area is now a small campsite, with a small store open on holidays, partially utilising the former village school's recreational area. The area was far-flung and hard to access, and was consequently one of the last rural settlements in Hong Kong. Wildlife like South China tigers, muntjacs, and wild boars were spotted, but soon declined in numbers due to deforestation by local Hakka villagers. Smaller animals such as pangolins and porcupines retreated into the remaining forests. From the campsite, the Cheung Sheung Country Trail provides an escape route via Jacob's Ladder to Yung Shue O. The MacLehose Trail continues southwards through the uplands of the Sai Kung peninsula, passing Wa Mei Shan and Lui Ta Shek. The trail then dips briefly into a small valley, before steeply ascending Kai Kung Shan. The view from the peak provides a 360-degree panorama over Three Fathoms Cove, Yim Tin Tsai, and other mountains in the Sai Kung West Country Park. Section 3 finishes by winding its way down to Kei Ling Ha and Sai Sha Road, the main thoroughfare connecting Ma On Shan and Sai Kung. There are toilets, water refilling stations, and multiple barbeque areas near the endpoint.
