Eryri (Snowdonia)

The highest and rockiest mountains in Wales, from Yr Wyddfa (Snowdon, 1,085 m) and the scrambling grounds of the Glyderau to the whaleback Carneddau and, further south, Cadair Idris and the rough Rhinogydd. Walking spans everything from heavily used paths on Yr Wyddfa to some of the quietest, stoniest ground in Wales. The park authority adopted the Welsh names Eryri and Yr Wyddfa in 2022.

Access in this park

The position in Eryri (Snowdonia)

Most of the high ground is mapped CRoW open access land with freedom to roam on foot. Wild camping needs the landowner’s permission, as everywhere in Wales.

Conditional Right to roam (Wales): Right to roam only on mapped CRoW open access land.

Permission needed Wild camping (Wales): Permission needed everywhere.

Designation as a park creates no right of access in itself — the law of Wales applies inside the boundary, and park byelaws, seasonal restrictions and closures can override the general position. This is general information, not legal advice. Full detail: access rights in Wales · check a specific grid reference.

Hill data from the Database of British & Irish Hills v18.3 (CC BY 4.0); park boundaries from the Office for National Statistics (OGL v3.0). Hills are assigned to a park by summit position, so a top just outside the boundary will not appear here even if the walk starts inside it.
