('to rise'). The latter is considered more correct, for as a plural form means 'uplands', but it is not any direct form of the word in the meaning 'eagle'.
Extent
Before the boundaries of the national park were designated, "Snowdonia" was generally used to refer to a smaller upland area of northern centred on the Snowdon
massif
A massif () is a principal mountain mass, such as a compact portion of a mountain range, containing one or more summits (e.g. France's Massif Central). In mountaineering literature, ''massif'' is frequently used to denote the main mass of an ...
. The national park covers an area more than twice that size, extending south into the area.
This difference is apparent in books published before 1951. In George Borrow's 1907 ''Wild Wales'' he states that "Snowdon or Eryri is no single hill, but a mountainous region, the loftiest part of which scalled Y Wyddfa", making a distinction between the summit of the mountain and the surrounding massif. ''The Mountains of Snowdonia'' by H. Carr & G. Lister (1925) defines "Eryri" as "composed of the two cantrefs of Arfon and Arllechwedd, and the two commotes of Nant Conwy and Eifionydd", which corresponds to Caernarfonshire with the exception of southwest Llŷn and the Creuddyn Peninsula.
In ''Geography'' ''Volume 26'', a journal of the Geographical Association published in 1941, Thomas Cotterill Warrington, writes a section titled "Nomenclature in the Mountains of Carnarvonshire" defining both "Snowdonia" and "Eryri". "Snowdonia" was described by Warrington as a "tourist's or mountaineer's term" which encompassed the district containing Pen-y-Gwryd at its centre. Its boundaries were described as stretching from the Conwy valley to Fairy Glen gorge (near Betws-y-Coed), then from the Lledr Valley towards

Following a two-year transition period, the authority announced in November 2024, the change would be kept due to its success in gaining support and adoption by many businesses and media.
Unlike national parks in other countries, national parks in the UK are made up of both public and private lands under a central planning authority. The makeup of land ownership in the national park is as follows:
More than 26,000 people live within the park, of whom 58.6% could speak Welsh in 2011. While most of the land is either open or mountainous land, there is a significant amount of agricultural activity within the park.

Geography
Mountains
The principal ranges of the traditional Snowdonia are the Snowdon massif itself, the Glyderau, the Carneddau, the Moelwynion and the Moel Hebog range. All of Wales' 3000ft mountains are to be found within the first three of these massifs and are most popular with visitors. To their south within the wider national park are the Rhinogydd and the Cadair Idris and Aran Fawddwy ranges. Besides these well-defined areas are a number of mountains which are less readily grouped, though various guidebook writers have assigned them into groups such as the "Arenigs", the "Tarrens" and the "Dyfi hills".

Many sections of dismantled railway are now used by walking and cycling routes and are described elsewhere. The Bala Lake Railway is a heritage railway which has been established along a section of the former mainline route between Bala and Llanuwchllyn. Other heritage railways occupy sections of former mineral lines, often narrow gauge and are described in a separate section.
Buses
The national park is served by a growing bus network, branded ''Sherpa'r Wyddfa'' (formerly Snowdon Sherpa). The network was relaunched in July 2022 with this new brand to reflect the National Park's promotion of Welsh place names. Thus the publicity and websites for the newly branded service only use these Welsh names, even though the publicity is also directed at monoglot English speakers.
Together with the network of buses, this provides a car-free option for tourists and locals wishing to travel across the National Park.
Climate
Snowdonia is one of the wettest parts of the United Kingdom; Crib Goch in Snowdonia is the wettest spot in the United Kingdom, with an average rainfall of a year over the 30-year period prior to the mid-2000s. (There is a rainfall gauge at on the slopes below Crib Goch.)

Economy
The area's economy was traditionally centred upon farming and from the early 19th century increasingly on mining and quarrying. Tourism has become an increasingly significant part of Snowdonia's economy during the 20th and 21st centuries.
Hill farming
The extensive farming of sheep remains central to Snowdonia's farming economy.
Forestry

Slate industry
The region was once the most important producer of slate in the world. Some production continues but at a much reduced level from its peak. The park boundaries are drawn such that much of the landscape affected by slate quarrying and mining lies immediately outside of the designated area.
Llyn Trawsfynydd
Llyn Trawsfynydd is a large artificial reservoir situated near the village of Trawsfynydd in Gwynedd, North Wales. With a total surface area of the reservoir is slightly more extensive than Wales's largest natural lake, Bala Lake at .

Tourism
Research indicates that there were 3.67 million visitors to Snowdonia National Park in 2013, with approximately 9.74 million tourist days spent in the park during that year. Total tourist expenditure was £433.6 million in 2013.
Hiking
Many of the hikers in the area concentrate on Snowdon itself. It is regarded as a fine mountain, but at times gets very crowded; in addition the Snowdon Mountain Railway runs to the summit.
The other high mountains with their boulder-strewn summits as well as , one of the few mountains in the UK south of Scotland whose ascent needs hands as well as feet are also very popular. However, there are also some spectacular walks in Snowdonia on the lower mountains, and they tend to be relatively unfrequented. Among hikers' favourites are Y Garn (east of Llanberis) along the ridge to Elidir Fawr; Mynydd Tal-y-Mignedd (west of Snowdon) along the Nantlle Ridge to Mynydd Drws-y-Coed; Moelwyn Mawr (west of Blaenau Ffestiniog); and Pen Llithrig y Wrach north of Capel Curig. Further south are Y Llethr in the Rhinogydd, and Cadair Idris near Dolgellau.
The park has of public footpaths, of public bridleways, and of other public rights of way. A large part of the park is also covered by

Recreational routes
The Wales Coast Path runs within the park between Machynlleth and Penrhyndeudraeth, save for short sections of coast in the vicinity of Tywyn and Barmouth which are excluded from the park. It touches the park boundary again at Penmaen-bach Point on the north coast. An inland alternative exists between Llanfairfechan and Conwy, wholly within the park. The North Wales Path, which predates the WCP, enters the park north of Bethesda and follows a route broadly parallel to the north coast visiting Aber Falls and the Sychnant Pass before exiting the park on the descent from Conwy Mountain. The Cambrian Way is a long-distance trail between Cardiff and Conwy that stays almost entirely within the national park from Mallwyd northwards. It was officially recognised in 2019, and is now depicted on

Use of in English
There have been calls to use the Welsh name for the area, ''Eryri'', in preference to "Snowdonia" in English-language contexts. In 2003, the pressure group Cymuned campaigned for such a change, inspired by other campaigns such as Ayers Rock being known as

as Qomolangma. In 2020, an e-petition calling for the removal of the English name was put forward to the Senedd, but rejected as responsibility lies with the Snowdonia National Park Authority.
In 2021, an e-petition on the same topic attracted more than 5,300 signatures and was presented to the national park authority. The authority was already considering its language policy, but stated that the petition encouraged it to take "decisive action", and it resolved to use Welsh names as far as legally possible in November 2022; it must continue to use "Snowdonia" in statutory documents. Before the decision, the authority had already prioritised the Welsh names by using them first and giving the English names in parentheses. The naming policy applies only to the national park authority.
In November 2024, the authority stated that the name change had been a "success" as many businesses and media had followed suit. The authority stated that a summer survey showed "strong support" from locals and visitors for the name change. While some concerns were raised over misconceptions by some that the Welsh names were new and mispronunciations, the authority stated that the change resulted in the park being more associated with a Welsh identity, and more different from other UK national parks. The authority is set to make a pronunciation guide and update its logo which still contains Snowdonia. Two days later the authority revealed the new logo that removed the name "Snowdonia".
