Gauja National Park is the most popular natural destination in Latvia. It covers an area of 920 square kilometers, and is located between the towns of Sigulda and Valmiera. The most interesting part of the park is the picturesque meanders of the river Gauja, the longest river in the country. Devonian sandstone cliffs which are in some places as high as 90 metres are very interesting here as well. Forests cover 60% of the park, but there are also numerous lakes.
