Its rough texture and strength make it ideal for features like driveways, walkways, and decorative rock beds. Trap rock is typically a dark gray with a tint of blue, providing a bold, dramatic contrast in outdoor spaces. Known for its ability to withstand weathering and heavy use, trap rock is a popular choice for creating lasting, visually appealing landscaping elements.
