The Fountain of Youth at North Park in Allison Park, Pennsylvania is a unique and tiny 0.1 mile out-and-back trail that leads from Kummer Rd to the Fountain of Youth. The Fountain of Youth is a natural spring that, in 1938, the WPA built a rock grotto around and was given a pump handle. The original intent of the Fountain of Youth grotto was supposed to make it look classically Roman, but today it sits in the woods looking like something out of Lord of the Rings. On the top of the grotto's rock face is the words 'Fountain of Youth' inscribed at the top.
The trail to get to the Fountain of Youth is extremely short, but steep, so watch your step going down. You'll have to cross the creek, but there's a small rock path to get across. You'll also hear a small 7 foot waterfall splashing down into the creek next to you. You can get a better view of the waterfall and the Fountain of Youth rock grotto by hiking 50 feet down Kummer Rd from the parking lot - as seen in the cover picture.
Parking can be found at the coordinates and there's a small turnout that's big enough for about 5 cars.
