Snowdon is the highest mountain in Wales and the highest point in the British Isles outside the Scottish Highlands. It has a peak elevation of 1,085 metres (3,560 feet) above sea level. The Welsh name for Snowdon is Yr Wyddfa, which means "the tumulus" or "the barrow".

Located in Snowdonia National Park, Snowdon is a popular destination for hikers and mountaineers, attracting around half a million visitors each year. There are six main walking routes to the summit, ranging from the relatively easy Llanberis Path to the more challenging Crib Goch ridge walk.

In addition to hiking, Snowdon is also a popular spot for rock climbing, mountain biking, and paragliding. The mountain is home to a variety of plant and animal life, including heather, bilberry, and mountain hare. The Snowdonia National Park Authority is responsible for managing the mountain and surrounding area to preserve its natural beauty and protect its biodiversity.

There is also a narrow gauge mountain railway that operates during the summer months, which takes visitors from Llanberis to the summit of Snowdon. At the summit, there is a cafe and visitor centre, as well as stunning views of the surrounding countryside and coastline.
