Trails close for a variety of reasons; both temporary and permanent. Trails often have seasonal open and close dates for when they’re accessible for use. Weather events, fire danger, or trail restoration and maintenance can also limit access to trails. For those that are closed permanently, it’s generally due to underuse and lack of maintenance resources, barricades, private property, and locked gates.
