You need a visa to travel to Senegal. You can apply through Visa Senegal.
Following the outbreak of Ebola virus disease in Guinea, Senegal has closed its borders with Guinea in the regions of Kolda (south) and Kédougou (south-east), and has also closed the Diaobe Market in the south of the country.
If you’re travelling to any of the affected regions you should follow the health advice issued by the National Travel Health Network and Centre. You should maintain strict standards of hygiene and avoid eating bushmeat.
You should avoid road travel in the Casamance region to the west of Kolda, other than in daylight hours on the main road from Ziguinchor to Cap Skirring and the main road north of the Guinea-Bissau/Senegal border from Sao Domingos to Ziguinchor. See Local travel
