Now I'll be serious:
The Northern Scottish Coast (Thurso - Scourie)
I had no idea about this area apart from a green twisty line on an AtoZ. I've never heard any friends talk about anywhere nearby apart from a friend who occasionally goes to Aberdeen. When I did do my version of the North Coast 500, like Dominic Cummings, it was hard to concentrate driving for every turn producing a cinematic landscape. It really is on a podium far higher than the Lake District for me.
The Western Cumbrian Coast
I always get annoyed that people who visit the Lake District are actually just visiting the same handful of places that get overloaded all the time. However, I enjoy the result that when you pass the Coniston turn from the South, traffic has largely disappeared and you are free to enjoy Foxfield, Broughton, Millom, Ravenglas and the coastline up towards Maryport. My particular stand out is Seascale beach overshadowed by Sellafield
