Cycling or walking around the island and visiting the cathedral... chatting with the locals in a totally relaxed, beautiful and safe environment. Mass tourism has not hit and the locals are chilled and friendly. The kids will hang out with you and follow you everywhere just because they are curious and interested. The lake is cobalt blue and perfect for swimming...
Cathc the ilala ferry once a week to get there or fly in on a very little plane with Nyassa Air. Stay at Mango Drift backpackers or Kaya Mawa for quirky barefoot luxury.
