Por Kai Shan via Pok To Yan and Heavenly Book Wall

The two peaks tackled on this hike are Por Kai Shan (婆髻山) and Pok To Yan (泊刀屻) mountains at 482m and 529m, respectively. These relatively benign-looking hills are visible from anywhere in Tung Chung and are quite steep.
Besides those two peaks, we also made a detour to a nearby attraction, the Heavenly Book Wall.
The Heavenly Book Wall is composed of two sheer vertical rock walls, approximately 8 meters high, aligned at a right angle. It looks like a giant book that’s been opened by divine force.
Starting our adventure at Tung Chung MTR, we walked toward Yu Tung Road in the direction of Ma Wan Village.
Continuing along the Wong Lung Hang Country Trail, the road is constantly uphill, and along the way, the mountain on the left is Pok To Yan.
At the end of the road is the beginning of the ascent towards Pok To Yan, go up the narrow staircase next to the Pak Lung Stream embankment. The entrance to the barren trail of Pok To Yan is on the left-hand side of the top of the steps.
The path is obvious; there are ribbons leading the way along the trail. The trail is shaded by trees, and you walk in the forest path, but soon the trail opens up.
Arriving at the first mountain, Siu Chi Fung. There is no open scenery, rather a dense forest, and no trigonometrical station.
After passing through, we came to Tung Sam Yan Teng. Tung Sam Yan Teng is 515 meters high; there is no trigonometrical station, however, it offers a view of the Airport, Por Kai Shan, Yi Tung Shan, Sunset, and Lantau Peak.
Follow and head towards Po To Yan in front; this short section is densely grassy. There are small bamboo trees on both sides. Just stay on the trail to reach the top of Pok To Yan.
Pok To Yan is a bot like Sai Kau Nga Ridge; it has four small peaks, but it is not as steep as Sai Kau Nga Ridge.
Come down the mountain on the other side, and go in the direction of Pak Lung Stream. There are many fork trails along the way; you must have a sense of direction when heading towards Heavenly Book Wall.
The ribbons lead directly to the main trail. At some point before heading out towards the main trail, turn right, along a short overgrown trail, you will emerge at the end, which seems to have no road.
There is a very sloping hill in front, which seems to be unworkable, and the floating sand is very slippery, so be careful when you go down.
At the end of the slope, you have to climb down a gap, about 2.5 meters high, make use of the tree roots on the cliff to climb down, then on the left is the magnificent Heavenly Book Wall in sight.
After enjoying the awesomeness of the Heavenly Book Wall, we climbed back the same way and headed back on the main trail which is the official trail from Pak Mong to Sunset Peak.
Once back on the trail, we walked about 300 meters before coming to the not-so-obvious trail heading up Por Kai Shan on the right-hand side of the trail; you must pay attention, otherwise it is easy to miss.
The trail is dense and overgrown at first, but it will gradually become obvious, and soon it will approach the top of the mountain.
Por Kai Shan is 482 meters high, overlooking the entire Tung Chung and Airport, Castle Peak, and Tai Mo Shan are very clear.
To descend to Tung Chung, follow the trail on the left on top of Por Kai Shan. Be very careful as the trail heading down is very steep and dense. There are trees on both sides of the trail that help you get down.
As you reach a fork on the trail, it is important not to go straight as this will head straight to Pak Mong, turn left and head down that trail, it will take you back to the main trail.
Once on the main trail, turn left, which seems like you are headed back towards the direction of Sunset Peak. After a while, you will see a trail on the right that heads down; follow that trail back to Tung Chung.
On the way, you will see the Caribbean Coast Residential area. The trail heading down is slightly steep and rocky. There are plenty of shaded sections to rest along the way.
Continue to descend until the concrete road, which is also the maintenance of the top of the slope. Go down the narrow stairs, and turn left after reaching the bottom, cross the catchwater, keep right to leave the trail, and join Cheung Tung Road.
Just keep walking on the left for about 10 minutes, and you will reach Tung Chung Station, and the adventure is over.
Overall, the hike is challenging and requires a lot of climbing, also passing through dense and overgrown trails. Although the trails are very obvious and have plenty of ribbon markers, this adventure is best accompanied by experienced hikers.
