The visitor center, Historic Quarry trailhead, and Picnic/Nature Trail parking areas accommodate automobiles, pickup trucks, SUV's, RV's, motorbikes, bicycles, and commercial tour buses.
The narrow and steep road beyond the Picnic/Nature Trail parking area makes it difficult or impossible for buses, RV's and vehicles pulling trailers to complete the scenic drive. You may unhook and leave trailers in the visitor center or Picnic/Nature Trail area parking lots and continue.
Bicycles must remain on designated roads.
All motorized vehicles are restricted to the main park road. Operators and vehicles must be properly licensed.
Snowmobiles and ATV's are not allowed.
