However, with the increasing development and urbanisation of Hong Kong, water quality has worsened resulting in the closure of several beaches previously suitable for swimming. These include Approach Beach, Ting Kau Beach, Anglers' Beach, Gemini Beaches, Hoi Mei Wan Beach, Casam Beach and Lido Beach in Tsuen Wan. In 2011, Lido Beach, Casam Beach, Approach Beach and Hoi Mei Wan Beach were reopened following an improvement in water quality.
