On phone: Open Google Maps → tap & hold on the spot → red pin drops → swipe up for details/share/save. On PC: Click any spot on the map → pin drops → info card shows at bottom.
It is not that difficult to drop a pin on Google Maps! All you have to do is open Google Maps, press long on where you want to mark something and a pin will appear. At that point you can save it, share it or obtain directions.
