Edited  Mar 27:

I have booked a rental car for 3 days(from Glasgow 03/23 - 03/26) to explore northern Scotland. The current road trip plan is Glasgow - Fort Williams - Inverness - Aberdeen - Glasgow. 

I'm flexible with the plan and welcome suggestions/recommendations. TTYS.

Visiting Scotland in May. Looking to explore Edinburg & Glasgow. Also, planning to do a road trip to one of the national parks. Flexible with my plans if anyone is willing to join me for the trip.
