There is a pub in Scotland where you have to hike 20+ miles to get there (or make your way across Loch Nevis). The Old Forge is located in Knoydart, on the west coast of Scotland in Inverie. At a Remote Scottish Pub, a Pint Worth Hiking 20 Miles (article unlocked)
In Knoydart, there are no roads connected to other towns, no major supermarket, and in some places, even no cellphone signal. But there is, of course, a pub.
The pub, which is known as the remotest pub in mainland Britain, used to be an 18th-century cottage and was closed every winter. But several years ago, residents raised over a million pounds to buy and refurbish it. The Old Forge is now open year round.
