Return route from Isle of Skye - Suggestions?
 

Hi all,
I will be visiting the West Highlands in early September. I plan to rent a car in Glasgow, then take the A82 along the western shores of Loch Lomond to Glencoe (2.5D/2N) then onwards to Isle of Skye (3.5D/3N). However, I'm undecided about which route to take back to Glasgow (or to Edinburgh if a one-way drop is warranted).

What route would you recommend, given the following interests/preferences?

• Not interested in history or museums. Prefer viewing ruins from the outside against a gorgeous backdrop, than taking a tour of the inside of a castle.
• Prefer mountains and dramatic landscapes to flat/low pastures or fields.
• Prefer sheer cliffs (think cliffs of Moher) to sandy bays
• Not a confident driver - so the fewer hairpin bends, the better
• Flexible start and end point. Coming from London, then onward to Ireland.

Routes that I've ruled out:

• Via Lochness
• Via Isle of Mull (i.e. Skye > Mallaig > Kilchoan/Lochaline > Toberymory/Fishnish)

Routes that I'm still considering:

• Via the Eastern side of the Trossachs (A82 > A85 > A84 to Callander or Stirling, then onwards to Glasgow)
• Fort William > Oban > Inveraray > Glasgow
• Fort William > Oban > Tarbert > Isle of Arran > Glasgow

Thoughts on the above routes? Alternatives?

TIA :-)
