Opting for a stopover in Hong Kong rather than a brief transit allows travellers to enjoy a second holiday with culture, food and memorable city views. Start with a cycle along the West Kowloon Waterfront Promenade for fresh air, public art and Victoria Harbour views. Then head to the Tsim Sha Tsui Promenade to take in the skyline and landmarks such as the historic Clock Tower. Retail fans will find Nathan Road lively, with a mix of premium boutiques and local markets.

If time permits, discover heritage spots like Man Mo Temple or the streets of Central, where historic and contemporary architecture sit side by side. Food lovers should be sure to try Hong Kong’s famous dim sum in districts such as Wan Chai or Mong Kok.

As dusk approaches, relax at a rooftop bar or waterfront café and enjoy the city lights across Victoria Harbour.
