The Cuban leader arrived in Paris today, two days ahead of the start of the official programme, sources at Orly airport south of Paris said.
Castro's visit is an indication of his island's improved ties with major powers following last year's restoration of relations with longtime foe, the United States.
On the back of that rapprochement the 84-year-old leader is now paying court to France, one of his most powerful European allies.
"This visit is important for Cuba's image," said Eduardo Perera, an expert in international relations at Havana University, specializing in Europe.
"It will undeniably make Cuba shine on the international stage."
Havana hopes the visit will allow Cuba to "widen and diversify its relations with France in all possible areas -- politics, economics, trade, finance, investment, culture and cooperation," said Rogelio Sierra, Cuban deputy foreign minister.
Hollande urged an end to the blockade, which was imposed in 1962, on his Havana visit.
Trade delegations have been flocking to Cuba, hoping to cash in on its highly trained workforce and natural assets such as its sundrenched Caribbean beaches, a draw for tourists.
Cuba, meanwhile, needs to tap new sources of income as its main ally and financial backer, Venezuela, remains mired in economic and political crisis.
They will also sign deals on transport, tourism and fair trade.
Bilateral trade between France and Cuba is currently worth about USD 195 million.
