History of Snowdonia National Park
The Snowdonia National Park has a rich history dating back to its establishment in 1951, the same year as the Peak District National Park as Britain’s third national park and one of the most important parks in England and Wales. Covering an area of 827 square miles (2,140 km2) and with 37 miles (60 km) of coastline, it stretches across parts of Gwynedd and Conwy counties.
Before the designation of the park’s boundaries, the term "Snowdonia" used to refer to a smaller area, mainly the highlands of northern Gwynedd centered on the Snowdon massif. However, the national park encompasses a much larger area, more than twice the size, extending south into Meirionnydd.
Traditional Snowdonia includes the ranges of Snowdon and its satellites, such as the Glyderau group, Carneddau, Moelwynion, and Moel Hebog, but it does not include the hills south of Maentwrog. This area holds unique significance in the history, tradition, and culture of Wales.
The Snowdonia Society, founded in 1967, is a registered charity composed of volunteers interested in protecting and conserving the area.
Origin of the name "Snowdonia" of the national park
The English name of the park derives from Yr Wyddfa (Snowdon), the highest mountain in Wales, which reaches an altitude of 1085 m. In Welsh, the park is known as Eryri. It is believed that the name derives from Eryr (eagle), though some suggest it simply means "highlands," as stated by Welsh scholar Sir Ifor Williams. In the Middle Ages, the title of Prince of Wales and Lord of Snowdonia (Tywysog Cymru ac Arglwydd Eryri) was used by Llywelyn ap Gruffudd; his grandfather Llywelyn Fawr held the title of Prince of North Wales and Lord of Snowdonia.
Before the national park boundaries were established, Eryri used to refer to a smaller area, specifically the highland region of northern Gwynedd in the Snowdon massif. However, the national park encompasses more than twice that size, extending south into Meirionnydd. This is reflected in books published before 1951, such as "Wild Wales" (1862) by George Borrow and "The Mountains of Snowdonia" (1925) by H. Carr & G. Lister. F.J. North, editor of the book "Snowdonia" (1949), mentions that when the Committee outlined the provisional boundaries, they included areas beyond Eryri. Traditional Eryri includes the regions of Snowdon and its satellite mountains, Glyderau, Carneddau, and the Moel Siabod group, but excludes the hills south of Maentwrog. This area, like Eryri, has a unique place in the history, tradition, and culture of Wales
Mythology in the national park
Folklore and mythology in Britain have been passed down through generations via oral tradition, evolving over the centuries. These legends and tales share similar images and structures throughout the region.
Mythology often teaches us that we are stewards of the landscape, with stories emphasizing the connection between the land and its inhabitants.
Yr Wyddfa, also known as Snowdon in English (which gives the park its name), has a rich history in Welsh mythology. It is said that the name "Yr Wyddfa" comes from the word "Gwyddfa," meaning "tomb" or "burial place." According to legend, the medieval Welsh king Rhita Gawr was buried at the summit of Yr Wyddfa after a fierce battle with King Arthur.
The Mabinogi, a collection of medieval Welsh stories, is a masterpiece of early British prose. Some of the best-known stories from the Four Branches of the Mabinogi take place within the boundaries of Snowdonia National Park, such as "Branwen ferch Llŷr" and "Math fab Mathonwy," demonstrating the rich mythological tradition associated with the region.

Mountain Trails for All Levels
In Snowdonia National Park, the mountain trails are varied and offer options for different skill levels and preferences:
Snowdon is a focal point for many hikers, though it can be very crowded due to the railway that reaches the summit. The summits of the massif are covered with boulders, with challenging climbs like Tryfan, a mountain that requires climbing skills and is popular among adventurers.
In addition to the challenging summits, there are quieter trails that traverse the lower mountains of Eryri. These trails tend to be less frequented and offer a more peaceful and serene experience. Some popular routes include Y Garn east of Llanberis, Mynydd Tal-y-Mignedd west of Snowdon, Moelwyn Mawr west of Blaenau Ffestiniog, and Pen Llithrig y Wrach north of Capel Curig. There are also more southern options, such as Y Llethr in Rhinogydd and Cadair Idris near Dolgellau.
The National Park has an extensive network of public paths, covering 2380 km, as well as 264 km of public bridleways and 74 km of other types of public roads. In addition, a large part of the park is covered by the public Right of Way, allowing visitors to explore and enjoy the landscape more broadly.
Flora of Snowdonia
The coast of Snowdonia National Park is a Special Area of Conservation, stretching from the Llyn Peninsula to central Wales, including valuable sand dune systems.
The park’s natural forests are primarily mixed deciduous, dominated by Welsh oak, although birch, ash, and hazel are also found. Some areas of the park feature large conifers, such as those in Gwydir Forest near Betws-y-Coed. Additionally, the northern part of Eryri is the only place in Britain where the Snowdon lily, an Arctic-Alpine plant, grows, as well as the rainbow-colored Snowdon beetle (Chrysolina cerealis).
The park is home to a diversity of wildlife and is protected under various designations, including Site of Special Scientific Interest, National Nature Reserves in the UK, Special Area of Conservation, and Special Protection Area for Birds. However, one of the main challenges facing the park is the uncontrolled growth of Rhododendron ponticum, an invasive species that threatens native flora and fauna. This rapid growth can suffocate local species and cause significant ecological damage, leading to desolate landscapes in some areas of the park.
Fauna of Snowdonia
Snowdonia National Park is vital for the conservation of habitats and wildlife in the region, with nearly 20% of its area protected under UK and European Union legislation. Half of this area is designated as a Special Area of Conservation under the European Habitats Directive.
Mammals in the park include otters, polecats, wild goats, and occasionally pine martens, although the latter have not been seen in years. The park is home to various bird species, including ravens, peregrine falcons, ospreys, merlins, and red kites. A famous resident in Snowdonia is the Rainbow beetle.
The park also has three sites designated under the Ramsar Convention:
- Dyfi Estuary Biosphere Reserve
- Cwm Idwal
- Llyn Tegid
Climate of the Eryri Region of Snowdonia Park
Eryri is known for having one of the wettest climates in the UK. For example, Crib Goch in Snowdonia is recognized as the wettest place in the UK, with an average annual rainfall of 4473 millimeters over the past three decades. This means that the region experiences a significant amount of rain throughout the year, contributing to its characteristic green landscape and the diversity of flora and fauna found in Eryri National Park.
Best Time to Visit Snowdonia National Park
The best month to visit Snowdonia can vary depending on your preferences and planned activities. However, considering reasonable weather and fewer crowds, the ideal months are April, May, September, and October. During these months, you are likely to find pleasant temperatures and fewer tourists, allowing you to enjoy Snowdonia’s natural beauty more peacefully.
If you are interested in outdoor activities such as hiking and climbing, the warmer and drier months are from June to October.
