Radal Siete Tazas National Park is a national park straddling the border between the provinces of Curico and Talca, Maule Region, Chile. It lies in a pre-Andean area close to Descabezado Grande volcano. The reserve's most popular feature is the area known as Siete Tazas (Seven Cups), which consists of seven consecutive natural pools with their respective waterfalls along Claro River. These waterfalls range from 1 to 10.5 metres. There are also two high waterfalls called El Velo de Novia (The Bridal Veil) and La Leona (The Lioness), with single vertical drops of 40 and 20 metres respectively.
Many kayakers paddle the smaller falls ranging from 1 to 10.5 metres (3-32 feet). Once kayakers enter the steep canyon the only way out is down. Many tourists congregate on platforms surrounding the canyon to watch the kayakers as they navigate the waterfalls. At the end of the run kayakers must make a quick move to shore in order to avoid the 40 meter waterfall. This is the end of the canyon where kayakers then hike out.
The reserve protects tree species mainly of the genus Nothofagus, including the threatened Nothofagus glauca and Nothofagus leonii, as well as Nothofagus macrocarpa, Nothofagus dombeyi, Nothofagus Antarctica and Nothofagus alpina. Also it is possible to find vulnerable and rare species, as are Austrocedrus chilensis and Maytenus chubutensis.
