Tourists who enter Uganda need a visa. This permit can be obtained at arrival at the airport and costs US $50 per person.
When to visit
Uganda can be explored at any time, though mountain hikes, gorilla tracking and other forest walks are more challenging during the rains, which generally peaks over mid-September to November and March to May. Dry season is officially from June till mid-September and from December till February. However, like in any other country of the world climate seems to be changing.
The temperature is constant whole year through: between 23 and 28 degrees Celsius (74-83 degrees Fahrenheit). Note that in some parts of the country, particularly in the mountainous areas, it can cool off at night.
