The famous "Twisted Sisters" are some of the best and most scenic twisty roads in Texas. RR 335, RR 336, & RR 337 are also favorites with the motorcycle crowd. Many motorcycle sites post maps of the area, for example: Beautiful Hill Country views, lots of tight curves and elevation changes. Experienced motorers will describe it as 'challenging'. Start in San Antonio, go up State Hwy 16 (another great road) through Bandera, to Medina, where you link up to RR337. If you run it as a clockwise loop, you will stay on rr337 all the way to Camp Wood, passing through Vanderpool and Leaky. Medina to Camp wood is about 58 miles. The Bent Rim Grill in Leaky is a welcome rest stop for food run by friendly Texicans. In Camp Wood you shoot North on 56 to pick up RR335, crossing and following the Medina river for about 33 miles to HWY 41 where you turn East, go about 14 miles, then South on RR336 back down to Leaky. There is a Motorcycle Museum on RR336 if you are into those things, I ate there once too, not recommended. The whole loop is an all-day skidfest if starting from San Antonio. Important to be fully fuelled in Medina. Also very important to watch for two-wheelers on blind curves and hills.
