Have been there inspecting a dead Ele while hunting the Chewore river that separates it from the Chewore blocks on its east side.
Mana Pools Nat Park is on Sapi's south and western boundary separated by the Sapi river with the Zambezi river as the northern boundary.
I can give you "Google earth" grid if you would like.
We often found good Buff spoor leaving springs on the Chewore river heading into the Jesse on the Sapi side.
Pfumbe Hill area is a great spot. This hill was used as a spotting outpost during the Rhino Wars and was home to a good Lion whilst I was there.
Plenty of Wild Dogs too.
I would see I you can spend some night in the fly camp as well as the river camp as this enhances the experiences.
