The path is just over 5 kms long but you can then carry on past the marina towards Brighton pier and beyond
Brighton to Saltdean with a cafe at Ovingdean also passes through Rottingdean . Guessing in total 5 -6 kilometres
You have the answer! You do not have to walk all the way and can choose to stop and return to the promenade above whenever.
I was just there again last week. From Brighton Marina to the very end, it is 4.5 miles one way. I added a few miles to that by walking along the promenade from Hove, rather than start at the marina where the actual cliffs begin. It's an incredible way to spend the day! Enjoy.
