Snowdon is Wales highest peak. Its also crazily busy with tourists most days. In order to avoid the main crowds, there are a many other routes that involve some scrambling and more interesting routes to the summit. One of these is the Snowdon Horseshoe route that takes in Crib Goch.
Its another UK classic scrambling route and probably the best overall route on Snowdon if you can cope with the exposure of the route.
This route combines the ascent of Snowdon via Crib Goch from Pen y Pass and descends via Y Lliwedd back to Pen Y Pass. A great outing and a long days hike.
