Bright nights and realistic driving days
Use the long light to choose a comfortable start time or linger at one stop. It does not increase the amount of driving you can do while rested. Set a finish time before leaving, especially after an overnight flight.
For a highland walk, check the road, trail and booked transport separately. A bus timetable or an available hotel room does not prove that every intended approach and walking route is open.
What to keep within reach
Bring an eye mask if light affects your sleep, plus waterproof layers and a warm top for exposed stops. A light summer packing list should still let you wait outside in wind and rain.
