Many times I have a journey to make where I also have to go via somewhere. Disappointingly Apple maps doesn’t not have this feature but Google Maps app does. Simply...
To add multiple stops to your next journey on Google Maps, launch the iOS app.
First enter the location of your final destination using either the name, postcode or co-ordinates. Once this is done, tap the three-dot options button in the top right-hand corner.
From the menu that appears, select Add Stop.
You can then add as many different stops or places of interest along your route and re-order them (by dragging-and-dropping the text boxes) accordingly.
