We will be spending 3 nights on Skye (Portree) followed by 3 nights on Mull (Tobermary) in September. We were thinking about adding an extra night on the road between the two isles. Any suggestions? One of our party heard that Oban was a must. I've heard that GlenCoe is highly recommended. Any thoughts or other suggestions would be very welcomed. Is a side trip to GlenCoe possible on the way from Portree to, say, Oban? We'll be driving.
