Late March is the good window for the Paris night drive and almost nobody uses it. The clocks have not gone forward yet. Sunset is just after seven and the blue window runs from about quarter past to quarter to eight. You are back at the hotel by ten. In June you sit around until half eleven for the same sky. March gives you wet stone as well. It rained on and off all week and the quais by Pont Alexandre III were still holding water on Sunday, so every lamp on that bridge came twice. Two practical things. The tower lights go for five minutes on the hour and a driver will time the route around it if you say so at the start. Say it at the start, not when you are already parked. And everybody stands at Trocadéro, so ask to be put down at Pont de Bir Hakeim instead. The metro crosses over your head there and it puts something in the frame with the tower. 6 degrees at nine, and the wind comes straight off the river at that bridge. Gloves.
