The Bronx Zoo and three other Wildlife Conservation Society zoos reopened Friday.
The official reopening of the Bronx Zoo comes after four days of members-only access, which started earlier this week.
The Central Park Zoo, Prospect Park Zoo and Queens Zoo also reopened Friday.
They are all open at reduced capacity, and everyone must reserve tickets in advance for specific dates and times.
On-site tickets are not available. Masks or face coverings are required for anyone ages 3 or older.
Social distancing protocols will be in place, and cleaning procedures will be enhanced, especially in areas that are highly touched.
Food will still be served, and lines at concessions or other stores will be monitored to make sure visitors are wearing their masks and staying 6 feet apart.
The traditional free Wednesdays at the Bronx Zoo will start next week and that also requires you to get a ticket online beforehand.
