VISITORS to Shibden Park are being asked whether they would be prepared to pay up to £3 to park their cars.
A £2 charge for weekends and holidays was introduced as a trial in April, with a £1 fee during weekdays.
In June objectors handed in a 600-name petition against the experimental charges.
That prompted the council set up a scheme enabling motorists to get a £1 off their parking ticket if they spent more than £2 at the Shibden cafe.
Calderdale Council would like to put in pay and display ticket machines and will be required to under take formal consultation.
But to judge customer feedback on the current charging system, a survey is taking place over the next two weeks – the busiest time of the year for visitors.
The council wants to know how people would usually travel to Shibden, why they use the park, how often they do so, how long they usually stay and whether they might buy a visitor permit.
They are also being asked about how much they normally expect to pay for parking at other visitor attractions and what they consider a reasonable fee for parking at Shibden.
