Local Bus Service Mojacar
I have found to my surprise, that there is an excellent local bus service in Mojacar (in normal times).
It runs on a loop that covers from the Indalo Hotel at one end of the town, passes up through the pueblo and back down, to continue on as far as Marina de La Torre. The fare is a very reasonable €1.20 per trip.
I have seen suggestions on other forums, that you'd be lucky to be able to get transport to get from one end of the town to the other in the evening - that taxis were supposedly extremely scarce.
In my subsequent experience, there are a sufficient number of taxis, plus with the bus service, there's no problem at all in getting from A to B.
This isn't counting the fact that there's also the bus service to Vera that serves Mojacar aswell.
