¼ inch pea gravel is one of the smallest sizes available. Its fine texture and smoothness make it ideal for.use in paths and walkways. It's also popular for children's playgrounds due to its softness underfoot. However, it's not suitable for heavy traffic areas as it can become unstable under pressure.
