Across representative exposed-rock terrain

Full regional climbing & scrambling outlook

Conditions for exposed scrambling across the area look fair (70/100). Some rock may remain damp or incompletely dried, especially in shade and seepage lines. Mapped summit-point geology across the representative hills includes volcanic rock and granite, gneiss or gabbro; moisture response can therefore vary substantially between crags and routes.
