CTLA (Community Transport for the Lewes Area) runs Dial a Ride Community Bus services which can be used by anyone unable to easily access public transport. This could be due to unsuitable scheduled times, mobility issues, additional need requirements, location or other reasons. All you need to do is register with CTLA (registration is free) and book your trip (subject to availability) up to the day before travel. For more information see http://www.ctla.org.uk/dial-a-ride/ or 01273 517332

The service is jointly funded by Newhaven, Peacehaven, Seaford and Telscombe Town Councils and can be used for any purpose – to go shopping, visit friends, cafes, local attractions and much more.
