How do I drive from Holywood to Cultra without joining the M3?

Holywood and Cultra are neighbouring locations along the A2 Belfast Lough corridor.

You can continue east along the local coastal road system rather than going back towards the M3 and Belfast. Cultra is associated with the Ulster Folk Museum and nearby estates; use the actual museum or address if that is your destination because a generic Cultra search covers several access roads. Check current signage at junctions and allow for local traffic around Holywood.
