Mountain Weather forecast - Snowdonia National Park

The Snowdonia Mountains are made up of 90 mountain peaks including the tallest mountain in Wales, Snowdon, standing at 1,085m. It can be divided into four areas with the northernmost area the most popular, including peaks such as Moel Hebog, Myndd Mawr and the Nantlle Ridge. Many hikers tend to concentrate on Snowdon itself regarding it as a fine mountain. However it can become quite crowded, particularly with the Snowdon Mountain Railway running to the summit.

Moving into Wales brings with it a return to the high, imposing peaks of the Lakes and Highlands. The area is most famed for Snowdon, the highest peak in England and Wales at some 1,085 metres above sea level. The peak welcomes around half a million visitors every year, of which four fifths scale the peak on foot, whilst the remainder opt to take the train instead.

One of the mountain's main attractions is the sheer number and variety of paths reaching the peak. This means that everyone from mountaineering novices to climbing experts should find a way up Snowdon that will suit their abilities or provide them with a sufficient test. The easiest is the Llanberis path which - being the longest - has the most shallow ascent. Conversely, the Watkin Path is widely seen as being the most demanding ascent, despite also being named the prettiest.
