Great little side trip in Kansas. Officially it's part of the Land and Sky Scenic Byway. From Goodland, go south about 10 miles on route 27, watching for a sign for Mt Sunflower. It's a right turn off route 27 and while the sign says 20 miles, I think it was more like 23 miles of well maintained gravel/dirt roads. My Honda had no problems on these roads.
There's no much actually at the site - a marker indicating that this is the highest point in Kansas, a log book where you can sign in, a Little Library lending library and a picnic table.
On the way out, you have a choice of exiting towards US 40, back to Kansas 27 or north to I-70. Since we were heading to Denver, we took the I-70 option. After about 20 miles of dirt/gravel roads, the route dropped us at I-70 just a couple of miles from the Colorado border.
Definitely a fun side trip - just don't set your expectations too high. AND - how many people can say they've been to the highest point in Kansas - bragging rights. read more
