Why go
Sandstone bouldering at Isatis. This is a session-planning record, not a topo — named problems below are a tick-list, not a guidebook reprint.
Access
Never climb wet sandstone. Brush, don’t tick the rock, stay on the sand, pack out everything. Local forest rules are not optional. If you do not know, do not guess. BMC Regional Access Database for UK venues.
Getting there
Parking: Forest car parks for this massif. Do not block forest tracks.
Approach: Pick one area per day. Follow the sand, not a new trail through the moss.
Classics (not a topo)
