Is there a website to find places to visit along a journey?
I think this solves your problem: www.roadtripradar.com/
You enter your start point, your end point, you tick all of the different kinds of places to visit along your route that you want to visit, you set the distance from your route, and bang! Your route is made! You can save it and make cool YouTube backgrounds for your trip, too.
It works in Britain, Ireland, the USA, Canada, Australia and New Zealand.
