About 100 people carrying signs and flags showed up at the Orange Circle around noon, according to the city's police department. Some were on foot and others protested from their cars.
Authorities say crowds at the "Reopen Orange County" protest dispersed peacefully and no arrests were made.
The protest comes at the heels of a handful of others throughout Southern California, including many in Orange County.
It also comes after thousands flocked Newport and Huntington beaches amid a heat wave over the weekend, which prompted Newport Beach city officials to consider shutting down beaches for the next few weekends.
The city council is expected to take up the issue on Tuesday. The council will consider closing the beaches on the first three Saturdays and Sundays of the month of May (May 2 and 3, May 9 and 10, May 16 and 17.)
