All my family live in Norfolk. N and E coast.
I agree with @Cyclebabble ’s list (love the Sea Marge and the other Luytens building in the village).
My family and their kids love walking, birdwatching, sailing, surfing, sea fishing
I love the coast from Brancaster to Winterton, the contrast between the wild expanses and vast sands, to the cliffs and rock pools of the fossil-ing beaches , and the cheerful resorts at Wells and Sheringham.
Norwich is a great city, I love the market, it has a good range of theatres and galleries.
I left for Uni and work and chose not to go back to live. I am now a city person, my family are not. My own family now is multi cultural. The attitude to diversity has changed immeasurably over the last 30 years but coastal isolation and insulation is real.
The sense of community in the villages and small towns my family live in has been strong.
I won’t be going back there for retirement. The health infrastructure is sparse, all my experiences of frail elderlies in the N&N have been terrible, worse in Lynn. And the travel times from the coast daunting. Public transport is bad, except for the bus that runs along the coast and the local rail network, but obviously only where it reaches.
I love visiting. If you ‘get’ Norfolk, the big skies, the expanses of marsh, the slowness, it’s wonderful, IMO / IME . If it isn’t your thing, it isn’t.
