The French capital is having three protests on 18 September, one of which is headed by the Yellow Vests movement, a Sputnik correspondent said.
Columns of protesters are being held back by the police cordons, with people chanting "[French President Emmanuel] Macron, we do not want your health pass."
The rallies are less crowded than in previous weeks, and the situation remains calm.
According to French broadcaster BFMTV, citing a police source, a total of 80,000 to 120,000 opponents of COVID-19 passes are expected to protest in France on Saturday, including 17,000 in Paris alone.
In July, Macron announced a series of new restrictions to contain the spread of COVID-19, including a special health pass indicating that a person has either been vaccinated or has a negative test result for COVID-19. Starting 9 August, the pass became mandatory in restaurants, bars, shopping centers, airplanes and long-distance trains.
The move caused widespread consternation in French society, with protests against the measure rocking the country every weekend. Last Saturday, a total of 121,000 voiced their objections across France, including 19,000 in Paris.
