Departing South from John Day is a delightful ride to Seneca....then NFS 16 East is a reasonable road which deteriorates the farther East you travel (terminating in gravel). Didn´t love the ´loop´ but it wasn´t horrible either. More of a remote tedious road with narrow lanes and potholes suited to the 1200GS crowd looking for ´adventure´ Marginal views, mostly abandoned feeling forest
Once you leave Seneca and get on NF 16 until John Day Hwy it is very remote. We traveled it all day and never saw another vehicle. You can see lots of wildlife. Last 7 miles on NF 16 (E. Camp Creek Rd, near Unity) is good graded gravel, rest of route is all paved. Watch out for livestock and deer on roads. On US 26 you will experience more traffic. Lots of camping opportunities.
