Written Directions
"Where the Red Fern Grows" is a children's book from 1961 set in Tahlequah and the Eldon Hill area. Start just east of Tahlequah at the Illinois River and head north on HWY 10. East on Chewey road, then Watts (route 59) down to Westville. Not much to see on that leg, and it's straight, but short HWY 62 is possibly more fun than HWY 10 with tributaries to the Illinois River and Eldon Hill, which is a lot of fun. Stop at the top here and check the view, then ride back to Tahlequah to finish up.
Scenery
Head north along the Illinois River, stop to camp or go canoeing. Beautiful country, plenty of twisties (some with serious consequences) and a 20 mile view from the top of Eldon Hill. This is as good as it gets in NE Oklahoma, and offers as much fun as you can find in Arkansas.
Drive Enjoyment
Highway 10 along the Illinois River and 62 offer some truly great riding. A few hard turns, especially on Hwy 62, but also a nice slow scenic and enjoyable ride if you want it.
Tourism Opportunities
There are plenty of gas stations and convenience stores along Highway 10 that cater to the summer canoeing crowd. In off seasons some of them may have limited hours. Don't expect much along Chewey Road of HWY 62, however, it's very rural. Watts and Westville have gas stations and convenience stores, but both are very small towns. Tahlequah is bigger and has auto parts stores, but not sure about a motorcycle mechanic for emergencies.
Motorcycle Road Additional info
All of these highways and roads have dirt roads that connect to them, so do keep an eye out for gravel.
