OCT East, Leisure park in Shenzhen, China

OCT East is a resort and theme-park complex of about 9 km² in the hills near Sanzhoutian, Yantian District, Shenzhen, facing Dameisha and Xiaomeisha beaches. It holds three parks — Knight Valley, Tea Stream Resort Valley and Wind Valley — plus eight hotels and Huaxing Temple. In the valley, a long flat-roofed white building with a green-roofed annex stands before a large white curved-roof arena, with red-and-white circular structures to its left.

OCT East was built by the OCT Group on a site near Sanzhoutian in Yantian District, with construction starting in 2004 and the resort opening in late July 2007 at a cost of CNY 3.5 billion. The area was already a scenic spot before development, and the same ground was the site of Sun Yat-sen's 1900 Huizhou Uprising, the Gengzi Uprising; in December 2009 work began on a sculpture park there with 18 sculptures.

Tea Stream Resort Valley includes Chaxi Valley, where the Swiss-style Interlaken Town stands beside the Chinese-style Chaweng Ancient Town. There visitors can try tea culture, and the Sānzhōutián tea fields, which predate the resort, were reworked into the Sānzhōu Tea Terraces.

Public transportation connects the park with central Shenzhen, including regular bus and metro services during operating hours. Internal cable cars and shuttle systems make it practical to explore different areas, especially when paths are steep.

The site of OCT East, near Sanzhoutian in Yantian, was where Sun Yat-sen launched the Huizhou Uprising in 1900, known as the Gengzi First Uprising. In December 2009 work began on a memorial sculpture park of about 7 hectares holding 18 sculptures. The forest train circles the whole resort, passing both built attractions and the Wutong Mountain foothills.
