>>967388Take midge spray, even if you don't think you'll need it. I had reasonable success with a brand called Smidge That Midge but it's pretty costly iirc. Consider a face midge net and make sure you always have your fly sheet zipped up.
There's a bus from Glasgow to Fort William but it doesn't run terribly often.
Make sure you have somewhere booked to stay in Fort William/Milngavie if you're hoping to sleep a night at one of the ends.
Milngavie is pronounced mill-guy. You'll look like an idiot if you say it wrong.
It will probably rain.
The Drover's Inn at the north end of Loch Lomand is incredible. Great food and atmosphere. Well worth the price, and 5 minutes from a huge campsite.
Ranoch Moor is beautiful. Take your time to appreciate it!
Resupplying can be a little tricky. Tyndrum is probably your best bet.
Wild camping in the Loch Lomand and Trossachs Park is forbidden so make sure you know where you're sleeping beforehand.
Wild camping is allowed elsewhere, so have fun and don't be an idiot.
Try and spot one of the steam trains!
I'll try and answer any questions you have but can't promise anything.
