About the Park & the Ringing Boulder Field
Ringing rocks are rare and can only be found in a few places worldwide. The seven-acre boulder field in Ringing Rocks Park is one of the largest in the world, with rocks piled up to ten feet high.
The boulders are made from diabase, an igneous (volcanic) rock that’s rich in iron. While scientists aren’t exactly sure why these rocks ring, several theories exist. Some attribute the sound to their high iron content, while others point to a combination of density and internal stress. Weathering may also play a role. Adding to the mystery, only some of the rocks ring when struck.
To make the rocks ring, you’ll need to bring your own hammer. You may need to strike a few before you hear a chime. The boulder field is just a quick, easy hike from the parking area, but the rocks themselves are uneven and can be slippery. Wear sturdy, closed-toe shoes if you plan to venture onto the rocks, and be sure to watch children closely.
Ringing Rocks Park Trails & Waterfall
Once you’ve heard your share of ringing, it’s just an easy five-minute hike from the boulder field to Bucks County’s largest waterfall, High Falls. Its water flow changes dramatically throughout the year, depending on recent precipitation. In a rainy spring, it can be especially impressive, while in the summer, the falls may slow to a trickle or even dry up. During an especially cold winter, the entire cascade can freeze into place.
