The Welch Spring ruins are reached on foot — about a mile and a half from the parking area at Akers Ferry, on a flat trail that follows the Current River. The hospital is a roofless rectangle of stone with its window openings still intact, standing on a flat above the spring. Behind the building, the spring runs out of a cave mouth that disappears into the bluff.
The spring is one of the bigger ones in the park, with a flow of around 75 million gallons a day. The pool is small but the run from the cave to the river is short and steep, and the colour of the water is good. The cave is gated to protect the bat population; you can look in but you cannot enter.
The site has the quiet melancholy that lost-cause projects acquire after a century — a setting that would be eerie in fog and is just very still in sunlight.
