#2 Crandon Park
If you are going to Miami, then you should make sure to look for Crandon Park. This beachfront is located on the south end of the city, in a Miami-Dade park that is part of Key Biscayne.
Despite being in one of the biggest hubs in Florida, this park is still not as crowded as other parts of the city, and they can boast of having a lot of space for parking, so it will not be an issue. They also have about 2 miles of gorgeous sandy beaches where you are bound to find a spot!
