Ntwetwe Pan doesn't have anything quite so spectacular as Kubu Island, though it does have a few marvellous old Baobabs and an island of its own.
This famous landmark (GPS: CHAPMA) was noted by Chapman, when he passed with Thomas Baines in 1861. It's a big tree and visible from some distance away. Note that there are endless tracks to the west of here, many made by nearby private safari camps, and so navigation can be especially difficult – rendering a GPS virtually essential.
Less well known than Chapman's, this tree (GPS: GREENS) is close to the only permanent spring in the area, Gutsha Pan, and still bears the inscription 'Green's Expedition 1858–1859' carved into its bark.
In the middle of Ntwetwe, on the west of the usual north–south route across the pans, Gabasadi Island is a low mound protruding from the surface of the pan. It's actually a fossilised, crescent-shaped barchan dune, which you'll realise if you climb it.
