Getting to The Gambia from Europe is so simple during the main tourist season, November - April.
Charter flights are available from most European countries.
Most travel agents would have details of flights and package deals. Sabina and Swissair also have scheduled flights. This company was the only UK travel operator to ignore the British government's unwise advise for operators to cease going to The Gambia, for the whole of the winter season, following the 1994 coup. I was there along with my wife during November - December and the country was as peaceful as ever. Sadly, it was a very difficult time for all those Gambians who rely on the tourist trade for their income.
