Lukusuzi National Park
This remote park is on the eastern side of the Luangwa Valley, slightly higher in altitude than the other parks in the valley. There are no facilities here at all – just a game scouts' camp near the gate, and an exceedingly poor track leading through the park. Equally, it is uncertain how much wildlife has survived the poaching, though it is thought that the dominant predator here is the spotted hyena, rather than the lion. The vegetation is mostly miombo woodland, dotted with grassland. Visiting the park requires a major expedition.
There is a track that turns east from the South Luangwa–Luambe track, and then continues through Lukusuzi National Park until it reaches the Great East Road. This track east to the Lukusuzi National Park starts (at least in theory), on the south bank of the Lukusuzi River (GPS: RIVERR). See under Luambe National Park, Getting There, By Driving, From South Luangwa
for more directions, and don't expect this turning to be very clear or well marked.
This track is bound to be impassable during the rains. The easiest approach to the park would be to take the Great East Road to Chipata, then turn north towards Lundazi. About 110km beyond Chipata there is a track on the left to Lukusuzi. There is a game scouts' camp at the park's entrance, so stop and ask them for advice about the park before you go any further. I haven't driven on either of these routes myself.
