Summary

Eryri is a mountainous region and national park in Wales, with lakes, steep peaks and inhabited valleys. Welsh language, settlement and patterns of land use remain central to the landscape’s identity.

Mountain forms and cultural continuity meet throughout this richly inhabited landscape. The scenery is rich in traces of human life, giving broad views a meaning beyond wilderness imagery.

Allow time

4 days as an initial allowance, excluding approach travel

Choose a base

A chosen Eryri gateway, such as Betws-y-Coed or Beddgelert

Getting there

Choose a valley base and a specific mountain or walking route, then use local buses or the appropriate trailhead parking. Pen-y-Pass serves only some Yr Wyddfa routes.

Plan ahead

Book Pen-y-Pass parking when required or use the bus network. Reserve the mountain railway separately if using it, and check the mountain forecast before choosing a summit day.

For the curious reader

History, landscape and context.

Snowdonia, or Eryri, is a mountainous region and national park in North Wales. It contains all 15 mountains in Wales over 3000 feet high, including the country's highest, Snowdon (Yr Wyddfa), which is 1,085 metres (3,560 ft) tall. These peaks are all part of the Snowdon, Glyderau, and Carneddau ranges in the north of the region. The national park has an area of 823 square miles (2,130 km2), and covers most of central and southern Gwynedd and the western part of Conwy County Borough. This is much larger than the area traditionally considered Snowdonia, and in addition to the five ranges above includes the Rhinogydd, Cadair Idris, and Aran ranges and the Dyfi Hills.

From inspiration to a practical plan

Plan your visit.

Physical demands
Low-level lakeside walks and long mountain ascents are very different outings; summit routes require fitness, navigation and suitable equipment.
The consequential detail
A high summit route requires mountain preparation; roadside scenery does not predict summit weather.
