Catch the number 10 bus to Albir or Altea. Albir is a lovely town, a bit more upmarket than Benidorm.

Altea is a beautiful Spanish town.

Only €1 each way on modern air conditioned buses.

Whichever town you end up in you can walk along the seafront to the other. There are lots of great places to eat and have a drink.

Thanks very much for your reply, and you are quite right Albir and Altea are indeed very lovely, and totally different from Benidorm - we have visited both several times.
I was actually looking for suggestions more inland than coastal as we have covered Benidorm to Denia and the bits in between and have visisted Villajoyosa which is in the opposite direction, several times too. We are looking for somewhere that is easily accessible from Benidorm on the bus or train.
