Singletrack is like a narrow trail that is only big enough for one person or bike at a time. It's like when you walk on a path in the forest and there's only room for you to step one foot in front of the other. Singletrack is special because it's usually made just for bikes. It might be twisty and curvy with lots of ups and downs, or it might be smooth and flowy. Singletrack can be found in parks, forests, and other natural areas. It's a great way to enjoy nature while riding your bike.
