Hong Kong is continually upgrading its attractions, whether for leisure, business or family activities. In 2009 nearly 30 million people visited the city – an increase on the previous year despite the global economic turmoil. The Hong Kong National Geopark in eastern Hong Kong opened in November, featuring geological changes and ancient volcanic activities over the past four hundred million years. Tung Ping Chau, with its interesting layered sedimentary rocks, marks the park's eastern boundary.
