A fine South Downs walk offering panoramic views. From the historic town of Lewes, the route rises onto the Downs then descends into Rodmell for lunch. Then a gentle climb back over the Downs to reach the sea at Saltdean. From here you can either catch a bus to Brighton (frequent service) or walk through some (or all 😬) of the way there along the seafront. (It's a further 5.25 miles in total).
