Mambo Poa Tours is a new tour agency located on the South East Coast of Zanzibar. We heard a lot of discussion about Zanzibar becoming over touristy and over-charged, but we did not find this the case to be on the south east coast. Jambiani is a perfect base to stay, and the boys from Mambo Poa had some really interesting tours, beside the usual tours. We did a snorkelling trip, a day out in Stone Town (ask them about a combo of Spice tour, City Tour and Prison Island - it was a day full of fun!) and to a place in the south of the island with an abandoned hotel site (definitely something different.) You can tell that the boys know their island and they were nice and honest guys to hang out with.
Is this your business?
