Bosque De Secuoyas, Cantabria.
A Beautiful forest of Sequoia trees can be found at the junction of A-8 and CA-374. It's a bit hard to find, but well worth the time. Who knew, 80 years ago, a forrestation project served to trasnplant Californian Sequoia, all the way here in Northern Spain?! The bosque includes about 600 sequoia trees, and is bordered by other species of pines, covering only about an acre of land (if I remember correctly). It's small, but enough that it's peaceful and quiet and completely magical!
