How to go on your own, and what it costs
Bush taxi Bissau–Canchungo–Cacheu; the riverfront and the fort are free, the channels are by pirogue hired at the IBAP post or from fishermen, with a park fee and a local guide inside the park.
Cost: Park fee small; pirogue and guide — check current prices at the Cacheu post.
Free or no-guide alternative: Cacheu's riverfront and the fort walls overlook the river and the nearest mangrove: roosting herons, pelicans and waders at dusk for free, no boat.
Who runs access
- IBAP – Cacheu park post (park authority) — Pirogues and guides.
Field-recording notes
Hydrophone territory: drop it from a paddled pirogue in a channel at slack water. Outboards are the noise; local pirogues will paddle if asked. Humidity high, salt everywhere; the harmattan brings haze but not much dust here. Ramsar site (2015); park fee and guide via the IBAP post.
