Every spring and fall, bicycling may be permitted on park roads while they’re closed to motorized, public travel. Roads will not be free of cars during these times: bicyclists will encounter employees, contractors, plows, and other administrative vehicles on the roads.
If you plan to bike on any roads open to public, motorized travel, check out our bicycling page.
The map below shows which road segments are typically opened to spring and fall bicycling (and other forms of non-motorized travel). The colored, dotted lines indicate seasonal differences. This map does not show current status: it is for trip planning purposes only.
