Located at James River Crossing on Ranch Road 2389 south of Mason, this boat ramp provides vehicle access to an exposed gravel bar island in the Llano River for launching kayaks, canoes, and small watercraft.

High-clearance and four-wheel-drive vehicles are recommended to navigate the rocky terrain. Access is limited to daylight hours (5 mph speed limit, no vehicle traffic between 10 p. m. and 4 a. m), and the area is subject to flooding during heavy rains.
