Parking - Know the Facts

It is unsafe and illegal to park in a way that:

  • Blocks emergency access gate or fire lane;
  • Blocks pedestrian gate or driveway;
  • Prevents horse trailer parking; or
  • Along any highway or a roadway where prohibited by sign.

All vehicles parked in a manner described above are subject to being ticketed/towed.

Never park in the roadway. The roadway is defined as the space between the white (fog) line and the yellow (center) line. If ANY part of your vehicle (tire, mirror) is between the white and yellow lines, your vehicle is a hazard and can be ticketed/towed immediately.

Because parking is very limited and our trailheads are quite popular, please show up early to get a parking spot.
