How to spread the trips
The programme alternates a long day (Prison Island and Nakupenda, then Kwale) with shorter trips. Durations come from the listings: three hours for the spices, four to five hours for the dolphins, five hours for Michamvi. Keep a margin between two trips if you like calm mornings.
Where to stay to link everything
The dolphin trip leaves from Nungwi, with hotel pick-up for some areas of the north and east and a meeting point in Nungwi for other areas. The other trips pick up from accommodation across the island. For Prison Island, the listing mentions a supplement on some south-eastern areas: read it before fixing your hotel.
Changing the order of the days
Nothing requires the suggested order. Place the sea trips (dolphins, Prison Island, Kwale) on the days when the weather looks most settled, and leave the spices or Michamvi for the rest. Dolphin sightings depend on conditions at sea.
