Visit Birling Gap and enjoy a splendid coastal walk to the Belle Tout lighthouse. The area is run by the National Trust so there are great facilities with a good sized car park, cafe, shop and visitor centre on the cliff top. This walk starts from the Birling Gap car park just a mile south of East Dean at the end of Birling Gap Road. From here you can pick up the trails along the The South Downs Way to the lighthouse. Belle Tout has been used many times in films and tv because of the spectacular location. It has been called 'Britain's most famous inhabited lighthouse'. There's fantastic views along to the nearby Beachy Head and 500 acres of open chalk grassland with a wide variety of butterflies and wildflowers to look out for.
To extend your walk just head east along the The South Downs Way to Beachy Head. Here you can walk across the highest chalk sea cliff in Britain with fabulous views and Perigrin Falcons to look out for. Continuing east from the headland will take you into Eastbourne.
If you head west you will soon come to Seven Sisters Country Park where you can explore the beautiful Cuckmere Haven on foot or by bike.
The village of East Dean is also nearby so you could start the walk from here and follow bridleways south to the coast. Just beyond East Dean you will find Friston Forest which has miles of good mountain bike trails and footpaths.
