When is the best time?

Peak: 1 Nov – 15 Jan. November to mid January, the heart of the leatherback and olive ridley season; hatchlings emerge about two months after each nesting peak

Active from 1 Sep to 28 Feb (September to February) in a typical year.

Time of day

Females come ashore after dark, mostly between 21:00 and 03:00 on a rising tide; hatchlings emerge at night

Depends on the tide: best around high tide. Check local tide tables.

What will you hear?

Mostly a sight, but the sound is worth having: the heavy breathing and sand-throwing of a leatherback digging, flippers slapping wet sand, and the surf of the Gulf of Guinea behind it.

Binoculars?

No binoculars needed. A nesting leatherback beside you in the dark; red torch only with the CEM patrol.

Where to go

How to go on your own, and what it costs

Approaching a nesting turtle without the CEM patrol is prohibited (protected species). Cheapest legal way: contact CEM in Grand-Béréby (bus from San Pédro) and join a night patrol for a donation.

Cost: Donation to CEM; check current prices.

Free or no-guide alternative: The beach is public and hatchling releases from the CEM hatchery are open to the public in season; walking the beach at night without the patrol is legal but you must not approach or light a nesting animal.

Who runs access

Field-recording notes

Only with a CEM patrol: red light only, no white torches or flash, approach from behind once the female is laying, and keep out of her line of sight. Nesting animals are highly sensitive; the eggs are protected by law and the local hatchery is how they survive. Surf is the bed of every recording, so a close, low-slung directional mic at the nest is the only way to isolate the animal. Nights are humid and windy; sand gets into everything. Hatchling releases at the hatchery are organised for visitors in season.
