The US President was due to fly by helicopter to Belleau Wood cemetery about 55 miles east of the French capital this afternoon.
As he landed earlier this morning, Mr Trump asked if anything is better to celebrate than the end of a war as he joins world leaders in France to mark Armistice Day.
Mr Trump arrived amid a row between France and the USA over Emmanuel Macron's call for a European Army, which dominated their first press conference together at the Elysee Palace.
The pair are also due to discuss trade while Mr Trump is in France, with the US leader saying they will see if they can "get over the line".
Mr Trump and his wife Melania will visit the American cemetery in Belleau later today to pay their respects to US soldiers who died in France during the First World War.
As he landed, Mr Trump tweeted: "I am in Paris getting ready to celebrate the end of World War One. Is there anything better to celebrate than the end of a war, in particular that one, which was one of the bloodiest and worst of all time?"
Despite this year's Armistice being the centenary year, the events could be dominated by the row between Mr Trump and Mr Macron.
In his first comments after greeting the French leader, Mr Trump said: "We want a strong Europe, it's very important to us and whichever way we can do it the best and more efficient would be something we both want.
"We want to help Europe but it has to be fair. Right now the burden sharing has been largely on the United States."

The prime minister was leaving a wreath-laying ceremony when two police motorbikes were knocked over near NATO headquarters.
Mr Macron has stood by his calls for European defence, and said: "It's unfair to have European security today being assured by the US.
"That's why I believe we need more European capacities and more defence to take this part of the burden."
The two leaders have forged a good relationship, often calling each other a "friend", but there was a level of tension when they met on Saturday morning.
As the press conference finished, Mr Macron smiled to cameras and placed a hand on Mr Trump's knee.
Canadian Prime Minister Justin Trudeau is also in France, where he paid homage to veterans at a First World War memorial in the north of the country.
He walked among the gravestones at the Canadian Cemetery number 2, where 820 casualties are buried.
