Hike #31, 52 Hike Challenge: Econlockhatchee Sandhills Conservation Area, Orlando. When I arrived at the parking area, I noticed a beaten-up car that looked like it had been abandoned. So I was a little apprehensive about entering the Econlockhatchee Sandhills Conservation Area, but glad I went ahead with the hike. The 706-acre conservation area features a diverse terrain – from sandhills to pine flatwoods to swamp. To reach Econlockhatchee Sandhills Conservation Area, take the 408 East to State Road 50 and turn left onto Lake Pickett Road (County Road 420). Econlockhatchee Sandhills Conservation Area will be about 2.5 miles ahead on your left-hand side. Distance: 3.2 miles.
