Our kids love this place as the hike is quite short (easy to reach within 1-2h from Tai Mei Tuk, Bride's Pool or Nam Chung) and the views from the pavilion are truly picturesque - green swamps, little villages below and towering mountains in the background.
The hike seems to be less popular than other parts of the Wilson trail which makes it a relaxing choice for a lazy afternoon.
