Loads of options for travelling north but it all depends on your budget.
Train: From Wolves (I assume Wolves as your name suggests that area) you?ll need to head for Glasgow or Edinburgh and thence from there to Inverness. Through trains are available from Wolves to Glasgow / Edinburgh. There is nothing direct to Inverness. The train option is not always the cheapest but, generally speaking, the earlier you book the cheaper it is.
Air: The only direct flight from Birmingham is operated by Eastern Airways but you?ll need a mortgage to use it, typical return fare is ?400 (ish). Other Airlines from Brum include Flybe and BMIBaby who will get you as far as Glasgow/Edinburgh or Aberdeen. Ryanair fly direct from East Midlands to Inverness on Mon, Tue and Fri only. Easy Jet fly direct to Inverness from Luton, Bristol and Liverpool.
Road: M6; M74; A80; M80; M9; A9.
Walk: Staffs & Worces canal; Trent & Mersey Canal; Macclesfield canal; Pennine Way to Kirk Yetholm; then head for Dunfermline and pick a Highland March route!!!
