Fort William

Fort William is a city in Scotland.

Hitchhiking out

South towards Glasgow or Edinburgh

Try to catch the A82 approx. 100-250m after the roundabout, there is a good place for the cars to stop (Link to OpenStreetMap). Do note though, that there is a lot of traffic going to all different kind of towns there and some drivers offer to take you just to e.g. Glencoe. This is in most of the cases a good idea still, as your chances of getting a ride are still good in those smaller towns along the A82.

Especially locals are your friend here, as in most of Scotland.

Other useful info

Lots of supermarkets there, a really nice (vegan) cafe is offering free water refill for everyone ('The Wildcat', OSM link).
