Core Path Plans
Each local authority and national park authority are required to create and publish a plan of core paths in their area. Here's the Dumfries and Galloway Core Paths one. You should be able to find the one for your local authority or national park authority on their website. Some are interactive and some not. You can get an overview of all the core paths in Scotland on the NatureScot website.
If you want to visit the National Parks, they have guidance about where to go, and more importantly, where not to go. They also have the latest information online, including live updates on car parks and toilet facilities.
