Alone in Scotland

I’m planning a 10-day trip to Scotland this summer. I’ll be spending the first five days in Glasgow, where I have a concert planned. After that, I’m taking a train to the Highlands, but I’m not entirely sure how to organize my time there.

I’d love to see a variety of things, including historic castles and, if the timing works out, the Highland Games. I want to make the most of my trip by exploring different sights and experiences. Any tips on must-see spots I shouldn’t miss? or if i can go alone

I cant rent a car
and im not veerryy big fan of tours
