Cacheu is a small city in northwestern Guinea-Bissau.
Cacheu is a town situated on the Cacheu river. It was once the earliest colonial settlements in Africa.
Be advised: this is a full day trip (8h-18h) if done in one day from Bissau. There will be a police/immigration checkpoint around Safim leaving Bissau going north. YOU MUST HAVE AT THE MINIMUM A COPY OF YOUR PASSPORT **AND** YOUR VISA PAGE. It is unclear if a copy will work all the time, but what is clear is that if you do have a copy of your passport main page, you must also have a copy of your visa. A copy of the page showing when you entered the country would be a good idea as well.
BISSAU TO CACHEU: As of June 2019, to get to Cacheu from Bissau, go to the “Paragem Central” behind the main Mesquita de Bissau (11.8646469, -15.6274868) (which is on and faces the main Avenida dos Combatentes da Liberdade da Pátria). Heading toward the airport from central Bissau the Mesquita is on the left after Mercado de Bandim but before the airport. Once at the Paragem, find the small covered space in the middle that has the ticket issuers at little tables. Just say “para Cacheu” and you will be shown who to pay. It should be about $1,000CFA to Canchungo, but may vary. You will have to change sept-place vehicle in Canchungo and buy another ticket there for Cacheu, should be around $500 CFA, and same thing, find the covered space in the center, find the guy at the little table, there may be various tables). The bus stop in Canchungo is at 12.075408, -16.034607. The stop in Cacheu is at approximately (12.2767760, -16.1648265) on the main road, right near the little seaside dock area and a quick 5 minute walk from the Fort/Museum. ASK when the last sept-place leaves to Bissau so you do not get stuck, since there is not a lot of traffic Cacheu-Bissau, the last one may leave at 14:30h...
CACHEU TO BISSAU: the sept-place leaves Cacheu from the same spot where you will get out at on the arrival journey. You will have to change at Canchungo again, and will be dropped off in Bissau on the main avenue before the Mesquita/paragem, where you can get a cab to anywhere in Bissau that you are staying.
Roads have been renovated in 2007 and are in very good condition.
It should be possible to take a canoa from Cacheu to São Domingos, not on Sundays however, unless you pay for the whole canoa yourself.
Tarrafe natural park can be visited by canoa. Regural (non tourist) canoa trips to Sao Domingos leave everyday around 10am (may vary with sea level) from the harbour (less than 3 euros as in 2008). It is possible to have lunch at Sao Domingos and return in the same day. If you want a customized trip talk directly with the fishermen.
"Tabancas", small villages around Cacheu, can be visited with local guides.
Memorial da Escravatura e do Tráfico Negriero (Aka the Historical Museum of Cacheu) - Museum and workshop spaces dedicated to remembering the slave trade.
Visit the cultural centre "Casa do Capitao Mor" created in collaboration with "Associacao de Cooperacao com a Guinea-Bissau" (Portugal)
The catholic mission sells local fruit jams to fund medical and health care activities among children.
There are some small restaurants at the harbour, serving rice with something - but probably only open for lunch. Otherwise you'll have to buy bread and canned food and cater for yourself.
The nightclub "Butu de Cacheu" is the only place to drink, dance and listen to african music.
Bungalows next to the harbour are resonably clean and not expensive. The hotel next to the fort was being renovated in 2007 and ought to open some time soon. Note: as in 2008, this is not open yet. Otherwise, ask around in town and someone will probably know someone, who can arrange accommodation.
Alternatively, take a car back to Canchungo or Bissau and spend the night there, there are better hotels and restaurants in Canchungo than Cacheu.
