Holidays in the South of England are underrated to be honest.
I loved the holidays down South as a kid to the likes of Devon and Cornwall.
I've also had 2 fishing holidays in the South East in the last 2 years and loved them. I always feel like I'm in another country when down there. The South East(minus London) is vastly underrated and has shitloads of natural beauty. The countryside down there is another level to anything I've seen in terms of countryside. The amount of Birds of prey, and wildlife in general, you see down there is unreal. Snakes, Badgers, alsorts.
England(in fact Britain, as Scotland has equally as much about it) isn't as bad as we make it out to be. We have a lot to see here, from medieval architecture, to forests, to the lake district, to amazing countryside. The only downside to this country is that our cities, minus maybe Liverpool, are wank.
