Holkham beach is pretty good if you like miles of empty sand bordered by pine woods, with galloping horses.
Cley is bird-central.
Wroxham is a centre for broads boat hire.
There is a railway line from Cromer to Norwich, passing through Wroxham.
Coasthopper bus stops all along from Cromer to Kings Lynn. Really useful for one-way walks, eg Burnham Ovary Staithe to Wells.
By bike, all locations will give access to the coast. If you are using a car it doesn't matter. If your family are using public transport, that is a deciding factor
