Be aware of faster drivers and pull off at an overlook to let people by. Although the speed limit along the Parkway is 45 m.p.h. If this is your style, great, but it doesn't suit everyone. Remember to share the road. Cars aren't the only vehicles allowed on the Parkway.
Bikes are very popular because of the great views and low speed limits.
So if you're in a car, always be on the look-out for bike traffic. Please leave things as you find them. The Parkway boasts many old cabins, interesting rock formations, and other historical and natural wonders. While it may be tempting to leave a reminder of your visit, remember that any kind of vandalism is ugly and destructive, and ruins the site for others. Don't forget to Recycle.
