UltrAspire HOT25 Hong Kong Island Trail Race（UltrAspire HOT25 香港島越野賽）

Mount Cameron, originally named Fei Ngo Leng, is a mountain in the central part of Hong Kong Island, about 439 metres high, situated to the south of and above the area between Wan Chai and Admiralty. Its summit and southern slopes lie within Aberdeen Country Park, near Wan Chai Gap, and Mount Cameron Road and Middle Gap Road run along its south-western hillside. The paths on Mount Cameron are rugged and precipitous, with steep steps; the summit is desolate and covered with igneous rock. Mount Cameron is named after Major-General Cameron, Commander of the British Forces in Hong Kong and Acting Governor of Hong Kong.

Jardine's Lookout is a mountain in Hong Kong, in the south-east of Wan Chai District on Hong Kong Island, in the area south of Tai Hang, with an elevation of 433 metres. Neighbouring peaks include Mount Nicholson, Violet Hill, Braemar Hill and Mount Butler. Section 5 of the Hong Kong Trail, Section 2 of the Wilson Trail, the Tai Tam Country Trail and Sir Cecil's Ride all pass over Jardine's Lookout. Between Jardine's Lookout and Mount Nicholson lies Wong Nai Chung Gap. Jardine's Lookout consists of thirteen roads named after prominent British figures of Hong Kong's colonial period, and it lies to the west of Perkins Road. Jardine's Lookout stands above Happy Valley and Wong Nai Chung Gap, and so does not belong to Tai Hang.

Mount Nicholson is a peak in Hong Kong, 430 metres above sea level. The peak lies in the south of Wan Chai District on Hong Kong Island, forming Wong Nai Chung Gap with Jardine's Lookout to its east and Middle Gap with Mount Cameron to its west. Its name is believed to be taken from an officer of the Hong Kong Volunteer Defence Corps.

Wong Nai Chung Gap (Chinese: 黃泥涌峽; lit. 'The gorge that yellow mud is gushing out of') is a geographic gap in the middle of Hong Kong Island in Hong Kong. The gap is between Mount Nicholson and Jardine's Lookout behind Wong Nai Chung (Happy Valley). Five roads meet at the gap: Wong Nai Chung Gap Road, Tai Tam Reservoir Road, Repulse Bay Road, Deep Water Bay Road and Black's Link. It is a strategic passage between the north and south of the island, though less so today since the opening of the Aberdeen Tunnel.
