Bárcena Mayor is a village nestled in the mountains of Cantabria, Spain in the municipality of Los Tojos, and is the only residential village within Saja Reservation within the Saja and Nansa valleys community.

 Said by the Cantabrian tourist bureaus to be the oldest town in Cantabria, it was declared a historic-artistic site in 1979 because of its state of preservation.
 With the declaration, funds were made available to repair the access road leading to it to make it easier for tourists to get to making it the end of the road (the road being CA-817, or Cantabria Provincial route 817).
 The road is in good condition, but the height of the surrounding mountains brings an early onset to dusk and a late dawn.It is known not only for its rustic architecture but also for its rural cuisine, such as, "cocido montañés" or game meat.
 Only residents may drive motor vehicles through the village, so most tour guides and advisers recommend walking through its streets to see its medieval character and look up at the surrounding mountains.
 It is now one of the most visited towns in the Cantabrian interior.
