Snowdonia National Park.
"Snowdon or Eryri is no single hill, but a mountainous region, the loftiest part of which, called Y Wyddfa, nearly four thousand feet above the level of the sea, is generally considered to be the highest point of Southern Britain. The name Snowdon was bestowed upon this region by the early English on account of its snowy appearance in winter. Snowdon is interesting on various accounts. It is interesting for its picturesque beauty. Perhaps in the whole world there is no region more picturesquely beautiful than Snowdon, a region of mountains, lakes, cataracts, and groves, in which nature shows herself in her most grand and beautiful forms."
