That was in the 90s and early 2000s. Morecambe is famous for a load of underpaid cockle pickers drowning when the tide came in, if I remember right. Southport and Blackpool were great when the tide was out, you could literally cross the estuary separating them if you were stupid enough. The beaches weren't always so fun unless you liked strolling through a mass grave of washed up jellyfish. And the tide was a force to be reckoned with when the sea wall along the prom was as tall as a house.
But that was then. All I've heard about Blackpool, for a long time, is that it became a stag/hen party hotspot and otherwise a dump. Southport was more or less a retirement community like Lytham St Anne's.
Shame really, just a part of the country that's been neglected since Thatcher. And you've got the lake district barely an hour's drive away. Such beautiful nature.
But the towns have seen better days. I remember seeing the infamous closed-down shop branded "Rhyl's Biggest Receiver of Stolen Goods":

The only other thing I'd add, like a commenter below, is that we went walking the other day on the frosty grassland of the beach, under a beaming wintersun, and it was really quite beautiful.
