Take-out
South Llano River State Park paddling accessSouth Llano River State Park is a popular destination that can reach capacity, so day-use or camping reservations are the cleanest way to secure the take-out plan.
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 South Llano River State Park first, then follow TPWD's current parking instructions for the gated Cupgrass site.
Additional access notes
- Use only the named public access points and direct river-portage paths because most of the shoreline between them remains private.
