Castle How & Lang How - Birketts
Key facts
Difficulty profile
Five independent axes, not one score. “Desk” ratings come from maps and guidebooks, not yet walked — treat them as a guide, not a survey.
☀️ Daylight & turnaround
Daylight is short from October to February — check today’s sunrise and sunset before you set off, and carry a head-torch and spare batteries. On short days, decide your turn-back time before you start.
Why this matters: 78% of Mountain Rescue call-outs come after midday — the day runs out on the way home, not on the way up. See also walking in bad weather and today’s conditions.

- Buggy: Stiles or rough going on the route.
- Knees: A long, steep ~33% drop around the 5.9 km mark — hard on the knees.
