Arch Rock in the Samuel H. Boardman Scenic Corridor is commonly described as being around mile marker 344.1 to 345 , depending on the source and the direction you’re driving. The corridor itself runs for about 12 miles along Highway 101 between Brookings and Gold Beach.

Quick direction note

If you’re coming north to south , Arch Rock is one of the first major stops you’ll hit after entering the corridor. Some guides place nearby features like Natural Bridges farther along, around mile marker 346 , so it helps to distinguish Arch Rock from the arch-like viewpoints deeper in the corridor.

Practical tip

The mile markers can vary a little by guide, but 344–345 is the safest estimate for Arch Rock. If you want, I can also map out the main Samuel H. Boardman stops by mile marker in a simple list.
