5 /5 Joshua Andrade: Beautiful little loop with a surprising amount of elevation change for Florida. Some very old oaks along the walk as well. The first part of the trail runs along the water and has some scenic views of the river. My walk was 1.52 miles walking to all corners inside the fort and doing the full loop. Not the longest trail but the Spanish Pong Loop trail system is just outside of the park entrance and is a literal 20 second drive if youre looking to add more miles.
