Permits, camping and season
Access and shuttle
Launch at Keller's Landing / US-87 and finish at TPWD's Castell Crossing lease for a 12-mile main Llano run. Use USGS 08150700 near Mason with TRPA's 65 cfs floor, keep the route behind the whitewater filter, and skip the trip if access, weather, or wood conditions are unclear.
Access map
Put-in
Keller's Landing / US-87Keller's Landing / US-87 is a route-source access anchor, not a developed TPWD launch. TRPA says the easiest access is on the southeast side by a steep muddy bank, so final water entry depends on current signs, parking, and safe bank conditions.
Take-out
Castell CrossingCastell Crossing is an active TPWD leased access through August 31, 2027, with daylight public use, designated parking, and no overnight camping.
Road shuttle
Stage the take-out at TPWD's Castell Crossing lease first, then drive back to the US-87/Keller's Landing access. Confirm signs, parking, bank condition, and no-posted-access changes before unloading at US-87.
Additional access notes
- Do not infer legal access or camping from private banks, gravel bars, ranch roads, or low-water crossings between the named endpoints.
- If the US-87 access is posted, washed out, muddy beyond safe carry, or lacks legal parking, skip the route rather than inventing a private alternate.
More route and safety guidance
- Use only public or permission-backed access. Castell Crossing is a TPWD leased take-out, but the US-87 put-in is a road-crossing access anchor that must be checked for current signs, parking, bank condition, and safety on arrival.
- The Llano rises quickly after Hill Country storms. Recheck USGS 08150700, radar, and local rain before launch, and skip the route if wood, flood debris, or private-bank limits make the access plan uncertain.
