The final stage of the Tour, which will start in Italy for the first time, is traditionally held on the Champs Elysees in Paris but has been moved to Nice with the French capital hosting the Olympic Games next year.
"For the Tour de France to finish far from its traditional Parisian finale is already a historic first," organisers said in a statement.
"But for the last two days of the 2024 edition, an extremely promising menu has been prepared, including all the necessary ingredients for major upsets at the top... on the Saturday as well as on the Sunday."
The penultimate stage will be a tough 132-kilometre ride while the 21st stage is a challenging 35-km time trial with climbs on La Turbie and Col d'Eze as organisers look to make competition for the Yellow Jersey tougher.
The Tour will start on June 29, with the opening stage from Florence to Rimini on the Adriatic coast.
