If you are planning to visit the best cliffs in England from Brighton then you have two options: By car: Brighton to Seven Sisters to Brighton (just use the Seven Sisters cliff postcode) By bus: take the Seven Sisters Brighton bus number 12X - it runs between Brighton and Eastbourne every 20 minutes Mondays to Saturdays. The same bus (12X) operates Sundays too but "only" every 30 minutes. The good news is that there is an additional service 13X providing a faster connection to Seven Sisters during high demand on Sundays.
