Finely crushed rock (crusher fines) is a useful alternative to paving trails that accommodates most trail activities.

Crusher fines is a finely-crushed stone mix that is often the byproduct of gravel operations. Crushed stone trails provide a user-friendly, all-season surface for all types and ages of visitors, including strollers, wheelchairs, and road bikes. If built properly crushed stone trails can meet the specification for a "firm and stable" surface as defined in current federal guidelines for accessible trails.

What You Need to Know About Building Trails with Crusher Fines
A crusher fine trail combines the rustic feeling of a natural surface trail with a surface type that's durable (but not concrete or asphalt). The natural gravel-like surface feels more like a trail than a hard surfaced path and fits in well with primitive settings.

Concrete Trails Keep You on the Right Path
If a hard surface recreational trail is in your future, you owe it to yourself to look at the benefits of cost, construction and long term reduced maintenance that can only come with a trail paved with concrete. (This article is sponsored content.)

Environmental Impacts from Mtn Bicycles, Electric Mtn Bicycles, & Motorcycles
The emergence of electric bicycles, commonly known as e-bikes, is a rapidly growing component of the bicycle market in the US. As a transportation option, they represent an opportunity to reduce vehicle use and emissions, as well as the physical barriers to cycling. For use on trails, they present similar opportunities to reduce barriers to cycling but, as a new use, present new challenges for trail management.
What is a sustainable trail? Building a sustainable trail system takes into account many factors. Most importantly, a sustainable trail should have as little impact to the environment as possible; this is accomplished through proper trail planning, design, construction and maintenance. A properly built trail will last for generations to come with little maintenance needed and will blend into the natural surroundings.
