Read Thread: Best easy hike near Orlando?
Are you thinking of the Ambassador Owl series in Merritt Island?
If so and you are headed to Brevard County there is Sams House Pine Island in Merritt Island and also the Enchanted Forest Sanctuary in Titusville.
Both offer either short or long hikes, depending on what you want to make of them as their are many trail heads/loops/spurs options so you are not stuck with hike in/hike out only trail.
Enchanted Forest is a combination of paved/dirt/sandy trails and frankly is one of my favorite park/trails. You could easily do a short hike here and stay on a paved trail that is much kinder to the knees than a sandy trail.
