What will you hear?
The world's largest monk seal colony (around 300 animals) in a few sea caves and cliff-foot beaches: barks, snorts and pup bleats over surf — but mostly heard from above, at a distance, on the viewing platforms.
Binoculars?
Telescope recommended. Seals on the beaches and cave mouths below the platforms at a fixed distance; scope recommended, binoculars minimum.
Where to go
- Cap Blanc satellite reserve & information centre — 8 km sandy track from Nouadhibou past the SNIM iron-ore terminal; small centre, viewing platforms at a fixed distance from the caves. The border with Western Sahara runs along the peninsula — stay on the reserve side. Map
- Ras Nouadhibou lighthouse — Seawatching over the cape: shearwaters, gannets, skuas on passage Sept–Nov. Map
How to go on your own, and what it costs
Taxi or own 4x4 from Nouadhibou: 8 km sandy track past the SNIM terminal to the reserve at the tip of the cape, daylight hours only; small entrance fee to the information centre and platforms, no guide needed.
Cost: Small reserve entrance fee — check current prices; taxi from Nouadhibou negotiable.
Field-recording notes
The caves are closed and the platforms are the limit — the colony collapsed in a 1997 die-off and disturbance is policed by the CBD-Hábitat project staff. What you can do is a long parabolic take of the haul-out beach in the still morning, or a hydrophone from the reserve shore if staff agree. The iron-ore port, the ore train (the longest in the world) and the ship-graveyard bay are loud and constant north of the reserve; the cape itself has only surf and wind, which is strong most afternoons.
