What will you hear?
Crakes and pygmy geese in the sand-mine pools, a wader roost at the Allahein mouth, and on rainy-season nights the beach with the surf and, if you are lucky, a nesting green turtle's breathing.
Binoculars?
Binoculars helpful. Crakes and pygmy geese on small pools at 20–50 m; binoculars for the roost on the Allahein sandbars. Turtle nights are red torch only.
Where to go
- Kartong sand-mine pools & wetland — Freshwater pools north of the village, the ringing site of the former Kartong Bird Observatory; open access. Map
- Allahein river mouth — Border river with Senegal; the sandbars hold the roost at high water. Fishermen's pirogues cross to the Casamance bank. Map
- Kartong beach (turtle nesting) — Village-run turtle protection with local patrols in the rains; ask at the village. Map
How to go on your own, and what it costs
Gelly-gelly or taxi to Kartong at the end of the coast road; the pools, river mouth and beach are all open and free. Turtle nights: ask at the village for the patrol.
Cost: Free (2026); a contribution to the village turtle patrol is expected if you join one.
Field-recording notes
Quiet end of the coast: the village, fishing pirogues and surf are the only noise. The border is 500 m away — carry your passport on the river. Turtle beach: red light only, no flash, stay behind the animal, and go with the village patrol. The observatory's website is no longer active; the pools are still there.

Bioko's southern beaches: leatherbacks, green turtles and the Caldera primatesBlack-sand surf, then the scrape and sigh of a leatherback digging a few metres away. At dawn the forest behind Moaba is one of the richest primate choruses in Africa: drill grunts and crowing, the chatter of red-eared monkeys, colobus roars, hornbills and the Bioko race of the grey parrot. Waterfalls drop straight onto the beach between the nesting bays.
Mangroves of the Congo mouth: manatees, turtle beaches and the only marine park in the DRCA mangrove dawn: the drip and click of the Rhizophora at low water, kingfishers, herons, fish eagles, the blow of a manatee surfacing in a side channel (a short, sharp exhalation, easy to miss), hippos grunting in the back creeks; at night on the beach, surf and a nesting ridley's scraping — and the Congo's current audible against the sandbanks at Banana.
Sea turtle nesting on Liberia's beachesA leatherback's long sighing breaths and flippers throwing sand on an empty Atlantic beach with surf and, behind, the forest's night — a sighting spectacle first, but the breathing of a two-metre animal beside you is a sound to keep.
