How to go on your own, and what it costs
Langdon Beck, Upper Teesdale: drive the B6277 / Cow Green road before first light, pull into a lay-by by the known lek and stay in the car — free, no booking, and the birds tolerate vehicles. World's End (Llandegla): the minor road over the moor gives roadside leks in the same way. Corrimony: the hide is only used on RSPB-booked mornings; the reserve trail is free by day. Never walk towards a lek.
Cost: Free from the car at Langdon Beck and World's End; RSPB Corrimony lek mornings are ticketed (check current prices).
Free or no-guide alternative: Roadside lek at Langdon Beck: sit in the car on the B6277 verge before dawn, engine off, windows down. Free, legal and low-disturbance.
Who runs access
- RSPB Corrimony – black grouse lek mornings (NGO) — Guided hide sessions in April–May, booking essential.
Field-recording notes
Leks are easily disturbed: arrive in full dark, use hides or the vehicle, and leave only after the birds. A rig placed near the lek before dark and retrieved late morning works; do not walk in during display. Capercaillie leks are off limits (Cairngorms 'Lek It Be' code) — they are not a target.
