Masaka is a city in Central Uganda.
From Kampala there are 'coasters' leaving from the New Taxi Park when they are full. Coasters are bigger than 'matatus' and smaller than coaches.
Coaches to Mbarara and further don't go through Masaka, but take a bypass. Make sure to get out at Nyendo to take a 'matatu' in to town.
There's a Sauna in one hotel (forgot the name), and a swimming pool at another hotel (also forgot the name) which are open also to non guests.
