This walk along the South Downs Way (SDW) consists of spectacular ridge walks with three steep ascents and a picturesque village in the middle for lunch and another one for tea, and with Beachy Head, Eastbourne promenade, beach and pier at the finish. It's a long but very rewarding walk. The route is well waymarked, the paths are easy walking, and the route is easy to follow. The South Downs are treeless and open, so there are good views throughout (weather permitting).
The walk starts at Southease Station, right on the SDW, and climbs the first ridge straight away, up to Itford Hill and then along the ridge to Firle Beacon, the highest point of the walk. There is an alternative start in Glynde in case the trains to Southease don't connect well.
At the end of the ridge you descend into Alfriston, a pretty village in the scenic Cuckmere Valley, with a village green dominated by a large church. Several good pubs and tea rooms and a village shop vie for your lunch business.
After lunch, follow the northern leg of the SDW up and over Windover Hill and down to Jevington (tea room [summer only] and pub) before a final climb to head south along another ridge towards the coast.
There is an inland shortcut into Eastbourne if you're tired, but the suggested route is to continue along the ridge to the coast, near Beachy Head. From here, head downhill into Eastbourne to join up with the SDW's Coastal Route and follow the promenade along the beach into town towards the pier.
