Where shall I go?

I recently passed my driving test so now have the freedom to go anywhere I want, when I want, but the trouble is I can't think of anywhere to go!

So I'm coming to Reddit for some inspiration (which I will probably regret!)

As my mother recently got a new car but still has a few months left on her Nissan Leaf, she's agreed to let me use it until it goes back. I was pretty sceptical about it at first as it's a bit on the low side for me, but it's lovely and easy to drive and costs next to nothing to run!

So, this gives me a handy limitation on where I can go, I want to be able to get there and back on a single charge!

I live in Durham, so where can I go in a 150 mile round trip?
