You need to be specific about what activity you are interested in because there are several. Beach, picnic, bicycling, wind surfing, boat launch, marina... Go to the Miami-dade parks department Web site. It's all there.
Restaurant was closed after Irma, not known when it's gonna open again. Not a recommended beach at all, the water is extremely dirty
The park close at Sunset. You can stay later ,because a local restaurant operate until 10:30 pm , but technically the beach area is close. The park open around 8:00 am ( no sure about this,you can verify online).
