DO NOT trust Google Map, GPS devices, and similar applications - from the east these direct you through Williams Oregon and over a confusing route on mountainous gravel roads.
Grants Pass from the I-5:
Take exit 58 to merge onto NE 6th St/OR-99/Redwood Hwy
From Crescent City, California:
Drive north on US-101
From Brookings, Oregon:
Drive south on US-101
Be aware that the last 10 miles on OR-46 East are narrow, steep and winding. Upon arrival at the Monument, please drive no faster than 10 miles per hour. Travel trailers and large RVs are not recommended beyond Grayback campground (mile post 12) due to the winding road. It is extremely important that you stay in your own lane. There are many blind corners. Watch for traffic crossing into your lane and watch out for wildlife. It could take you up to 60 minutes to reach the caves from the intersection of US-199 and OR-46 in Cave Junction. Car sickness is a definite possibility.
