Is there a bus for South Beaches?

Hello,

We have been to Barbados many times via cruise ship. We have been to Sandy Lane, and Paynes by bus which was very easy.

This time we would like to see Bathsheba, Bottom Bay and Crane, continuing on to the Carlise Bay area and cruise ship at end of day.

We were going to hire a driver, but we would rather take the bus if it is easy to do and there is a route along those beaches.

Any advice would be appreciated.
