Access and shuttle
If TPWD confirms Cupgrass access is active, launch through Bailey Creek and continue to Junction City Park for a 15.6-mile South Llano day route. The spring-fed water stays gentle overall, but the long mileage and midpoint state-park portage make this a real planning route rather than a casual hour float.
Access map
Put-in
TPWD Cupgrass AccessTPWD's Cupgrass page describes a gated leased access and launch via Bailey Creek, but its published lease term ends August 31, 2026. The current TPWD leased-access index still lists Cupgrass; confirm the lease and launch are active before relying on this put-in.
Take-out
Junction City ParkAt South Llano River State Park, paddlers must exit at the designated location before the damaged bridge, portage around it, and reenter downstream.
Road shuttle
Confirm current Cupgrass lease and public-launch status with TPWD before planning this shuttle: its individual access page lists a term through August 31, 2026, while the current leased-access index still lists the site. If access is confirmed, stage the take-out at Junction City Park first, then follow TPWD's current parking instructions for the gated Cupgrass site. Leave real margin for the midpoint state-park bridge portage.

Access planner
Choose your launch and take-out
This changes launch and take-out logistics, not today's river score.
TPWD Cupgrass Access to Junction City Park is about 15.6 mi. Use the planner to compare shorter access pairs.
Additional access notes
- Use Junction City Park as the intended public finish and avoid treating nearby private or bridge-adjacent banks as alternate take-outs.
More route and safety guidance
- This longer chain adds more mileage, sun exposure, and fewer convenient public exits than the short official splits, so low-water scraping and fatigue matter more here.
- Heavy rain can raise the river quickly, and the intended public finish is Junction City Park rather than improvised banks near town.
