Hike #9, 52 Hike Challenge: Econ River Wilderness Area. Surrounded by bland subdivisions on all sides in Oviedo (3795 Old Lockwood Road), the 240-acre Econ River Wilderness Area is a welcome oasis! I have to admit I got lost a few times (make sure to pick up a trail map at the entrance!) and some of the trail was flooded, but I eventually made it to the river. A very scenic and relaxing hike! Distance: 2.7 miles.
