It’s no more than a 2.5-3 mile loop! There are a couple loops that are smaller too!
Takes about 1 hr to walk trails.
Here's a trail map: www.marioncountyfl.org/home/showdocument?id=2813 and a bit more about them: https://floridahikes.com/silver-springs-conservation-area
I haven't been there in a while but there should be a 1-mile loop and a 3-mile loop... The map should be posted at the trailhead. If not somebody will post a more detailed answer soon..
