Simon Williams of the RAC said: "Once upon a time going to the beach was a cheap day out. Now unfortunately sky-high parking charges means day-trippers and holidaymakers don't just have the weather to worry about, they also have to be extremely shrewd about where they park so as not to burn holes in their pockets.
"Plan ahead by doing your research in advance so that parking charges don't come as a nasty surprise."
An LGA spokesperson said: "Tourism is hugely important to councils, which recognise the value of the visitor economy to local growth, jobs and prosperity in their area.
"Councils strive to set parking charges which benefit both visitors and residents. This means having to strike a balance between discouraging people from clogging spaces all day while not putting off people and visitors from shopping locally."
