Why go
Gritstone bouldering at Ilkley (Cow and Calf). This is a session-planning record, not a topo — named problems below are a tick-list, not a guidebook reprint.
Access
Check BMC RAD before you travel. Nesting, erosion and landowner notes change. Do not take a forum post as permission. If you do not know, do not guess. BMC Regional Access Database for UK venues.
Getting there
Parking: Use established public parking or signed laybys. Do not block gates, driveways or passing places.
Approach: Follow established paths. Do not cut new lines through heather or crops.
