Hike #35: 52 Hike Challenge: Lake Harney Wilderness Area, Geneva. A hidden gem, the Lake Harney Wilderness Area is way off the beaten path, but well worth a visit. It was a foggy day, but I took the Flagler Trail to the River Loop, which took me up to the St. Johns River. Then I walked back to the parking lot and found the Floodplain Loop Trail, which took me to a very cool observation tower overlooking Lake Harney (which I could barely see due to the fog). Unfortunately, I took photos with my new camera and I have yet to figure out to transfer them, but will add some images soon. Wildlife Sighting: Bald Eagle. Distance: 2.4 miles.
