Tour Scotland video of a beautiful Summer drive on a single track road over the mountains from Glen Quaich on ancestry visit to Kenmore and Loch Tay in the Perthshire Scottish Highlands. This one of the most scenic drives in Scotland. Scottish poet, Robert Burns travelled this route in 1787. This road is only wide enough for one vehicle. It has special passing places. If you see a vehicle coming towards you, or the driver behind wants to overtake, try to pull into a passing place on your left, or wait opposite a passing place on your right. Give way to vehicles coming uphill whenever you can. If necessary, reverse until you reach a passing place to let the other vehicle pass.
