Start by going through Falls City crossing the brige to Chamberlain road which will turn into Valsez road. Now this is a long trip on logging roads out and back. Over 40 miles round trip. Follow signs as if you were going to Valley of the Giants. https://www.oregonhikers.org/field_guide/Valley_of_the_Giants_Trailhead
As you are following the North Folk of the Silez river you will come to a road called the S-Line only a few miles from the trailhead to the VOG. You will turn right here at (44.920 -123.696) Follow this for about 7 miles and turn right at (44.9032 -123.65726) after that take your next right, then take the next left. This will take you all the way to the summit. The last 1/2 mile requres a 4x4 vechicle. You can drive to the top if you have enough guts. I decided to walk about 1/4 mile of it which there is a spot to park and get turned around with a full size truck. Nice easy walk and when the weather is nice views all the way to the ocean can be seen.
