Bus service from La Tercia?

Hi Everyone,

I have a place on UGR La Tercia and was wondering if it was possible to get a bus from La Tercia village to anywhere on the coast for a day out this might be via Balsicas or Sucina? Also, if there was a bus to Balsicas it would be handy for catching the train to Murcia or Cartegena.  You do get fed up of driving everywhere and its nice to meet people when your traveling.

Cheers
