- Time

Our own short loop on Castle Hill Local Nature Reserve, 16 hectares on the cliffs beside Newhaven Fort: up from the car park on Fort Road past the fort, the Victorian fort of 1864-71 on the cliffs above the harbour, and out along the Cliff Top Walk with the breakwater and the sea below, then back inland. The fort itself is a paid museum.
The ground
'Many of the footpaths have lots of steps and are on steep slopes,' the council says, with a surfaced path from the car park up to the cliff top. Chalk cliffs along the seaward side: keep well back from the edge.
Livestock
None mentioned by the council.
