This is a battlefield trail taking in 10 stations where you will see ammunition magazine, anti-aircraft batteries, pillboxes and bunker structures along the Wong Nai Gap in what is today the Tai Tam Country Park on Hong Kong Island. It is also the northern part of the Tai Tam Country (loop) Trail. The Wong Nai Chung Gap Trail is 2.8 km in distance, paved throughout and mostly flat with a slight descend of 50 metres from start to finish, making this one of the easiest hikes you'll find in this area of the city.
The trailhead is found just before the Parkview Residential Towers on Wong Nai Chung Gap Road, at the same small carpark where you find the Hong Kong & Wilson trailheads. The trail is very well marked with direction signs and each of the 10 stations has an posted information boards, describing the war relic, important notes about battles faced here as well as the allied soldiers involved in the heavy fighting that took place here during the Japanese invasion in Dec 1941.
Along the trail, you will see not only important historic war relics but nice vegetation as well as outstanding viewpoints of the Wong Nai Gap area, Happy Valley, the Hong Kong Skyline, Victoria Harbour and the Kowloon Skyline in the distance.
Note: You can use the Hiking Trail HK app on your mobile to follow the trail but in all honesty it is not really necessary due to the very good trail signage throughout. Do note that Stations 9 and 10 are back up the Wong Nai Gap Road around, almost directly across from the Hong Kong Cricket Club. They are situated on both sides of the Esso petrol station, these are the only two that roadside. The first 8 stations are back on the main trail within the Country Park.
Note: War history buffs will find this to be a rewarding hike and trail. You may also enjoy seeing the Pinewood Heritage Trail, seeing the war relics in the Lung Fu Shan Country Park on the northwest side of Victoria Peak. On the Kowloon side, try the Devil's Peak Battery and Redoubt as well as the Shing Mun War Relic Trail on the old Gin-Drinkers Line just south of the Shing Mun Reservoir.
Note: For those interested in Hong Kong's best viewpoints, you can combine a visit to the Wong Nai Chung Gap Trail with an ascend up to Jardine's Lookout which is a 1 km climb up the shared Hong Kong and Wilson Trail mentioned above. From 430 metres, this is one of the very best viewpoints of the HK's famous skyline and Victoria Harbour. Do this detour hike first, descend back from where you came and you'll be at the start of the Wong Nai Chung Gap Trail, where you can then do the easier battlefield hike.
