Mountain ridge among Horní Maršov, Žacléř and Svoboda nad Úpou. It creates the most eastern part of Giant mountains.
Thanks to its natural trasure it has been proclaimed as natural reservation. At the downhills of the ridge the gold and silver were mined from 16th to 18th century.
Through the ridge goes instructive trail. The most important mountains in the ridge are Dvorský les, Mravenečník or Červený hill.
