Do it yourself or book

Without booking, count about 30 to 40 USD for a shared boat return (often negotiable) plus the island entry, 4 to 10 USD depending on sources. A booked tour simplifies things: transfer, entry and sometimes lunch included. Avoid touts at the port.

What to check

Island entry, lunch, mask and snorkel, transfer from the north or east (over an hour by road). See the Prison Island page.

When to go

In the morning, in the dry season; in March to May some crossings may be cancelled. See when to visit Zanzibar. With a family, see Zanzibar with kids.
