I have fished the South Llano R. for almost 25 years. So, come to Junction and head toward Rocksprings. In about 15 miles from Junction you will come to a river crossing. Launch here and you can float/fish to the CR 150 bridge (nice TPWD constructed parking area to leave a vehicle). This float is mostly a half day float. Lots of Guadalupe Bass. If you want a longer float launch at the CR 150 site and float all the way to State Park, 9-10 miles and all day. The fishing and scenery is much better above the State Park than the float from the State Park to the town of Junction (getting out at FM 2169 or Flatrock Road as locals call it). Fishing right now is great with cooler weather setting in. Use small plastics i.e. crawfish, small finesse worms etc., some small flashing type baits. Top-waters also good, little poppers, tiny torpedoes etc. This would be a good weekend as everyone will be deer hunting and nobody on the river.
