The main trail in the preserve is a boardwalk that travels through mangrove swamp to a view of the intercoastal waterway. A sandy trail intersects the boardwalk to make a loop through a shady forest of cedar, palmetto, and Brazilian pepper. The boardwalk is a little over a mile roundtrip. I think this is probably a good bird watching trail but we saw very few on the cool, cloudy day of our visit.
The boardwalk section is accessible. We tried the the sandy trail going to the west and found too many roots.Traveling east we encountered fewer roots but we did hit a swampy area. The trail passes through the parking lot (where we stopped) and continues to return to the root filled section and the boardwalk.
The main parking lot is large enough for any RV but the entry road is narrow, one lane,and slightly overgrown with trees. Another option is the lot in the park behind the George Wickline Senior Center in Flagler Beach. Preserve 29.47626, -81.13344
