If you don't have a car but want to go on a breath taking coastal walk in England, I highly recommend Seven Sisters, an undulating walk from Eastbourne south of England.
The train journey from London Victoria Station to Eastbourne takes about an hour and half, and once you arrive you have a couple of options. You can start the walk from the station, heading towards South Downs Way which is the foot of Beachy Head. That takes about forty minutes. Alternatively, you can catch the number 12 bus from outside of the station and go directly to Seven Sisters Country Park and walk the 12km back to Eastbourne. The bus journey takes about 20 minutes. When I went, I walked from the station as that entire weekend I walked 48km all the way to Brighton.
The hard work starts once you get to South Downs Way as that's where the 160m ascend up the cliff to Beachy Head starts. This is also where you are rewarded with the first sight of the magnificent Seven Sisters ahead of you, and from there on all the hard work walking up and down the hills are worth it. To give you a bit of idea, it took us about an hour and a half to get from Beachy Head to the lighthouse that you see in the centre of the photo below, and another two hours or so to get down to the seashore by Seven Sisters further ahead.
The entire walk is along the edge of the chalk cliff hence the white cliffs. This can sometimes be quite dangerous as parts of the cliff may fall due to erosion or after heavy rainfall. Still, that didn't stop us from crawling as close to the edge as we dared to take photos.
After the light house, it took us over another hour to get to Birling Gap where we took a short break. The distance we walked wasn't actually very far, but I was with a walking group and we were chatting and enjoying ourselves as we walked that's why it took quite a while. If we had walked briskly we wouldn't have been able to spend so much time soaking in the spectacular view.
Seven Sisters is so called is it has seven undulating hills. In between the first few hills there is a staircase that takes you down to the seahore. It's a pebble seashore and quite popular with people who probably walk here from the Seven Sisters Country Park. We lingered around for a while, watching other people enjoying themselves before we left as there was still another 5km to our hostel for the night.
