About 35km out of Kampala, the 453-hectare Mpanga Forest Reserve is a decent option if you want to escape the chaos of Kampala for a day or two. It's best known for its 181 species of butterfly, while red-tailed monkeys can be seen during the day and bushbabies during guided night walks (USh5000 per person).
Most travellers visit on a day trip, but there's lodging at Mpanga Ecotourism Site .
Take a Masaka minibus (USh4000, one hour) and get off at Mpanga, walking the last 800m.
