Plan from real features
A filming-location visit should explain surfaces, distances and facilities clearly enough for visitors to make their own informed decision.
Town-centre streets and Market Place are the compact part of the itinerary. Verify the chosen car park, dropped kerbs, market-day changes and toilet opening before travel.
The quay and beach are separate. Holkham Estate states that Beach Road car park has toilets nearby; beach access includes a tarmac slope, while sand remains a variable surface. An accessible electric beach bus operates seasonally, but the vintage bus is not wheelchair accessible.
Accessible parking is provided. A boardwalk leads towards a viewing platform, but shifting sand and the transition from the boardwalk can affect independent access onto the beach itself.
Wind, tide, heat, cold and long exposed distances can change the practical difficulty. Build in a shorter alternative and check current conditions on the day.
