This loop threads through the heart of Snowdonia, combining slate-era heritage, mountain passes, and classic Welsh coast views.

Practical notes
Narrow mountain roads, livestock, and sudden weather changes can slow progress, especially on the Llanberis and B4407 mountain roads. Park only in signed areas around popular viewpoints and trailheads, as roadside spaces fill quickly in peak season.
