Cosumnes River preserve features a dock for you to launch your canoe or kayak from. The river offers excellent flat water allowing for excellent boating opportunities throughout most of the year. The Cosumnes is the last free-flowing river from the mighty Sierra Nevada Mountains into the Great Central Valley. Paddlers can enjoy a scenic glide through the river’s sloughs and main channel, cruising along riparian forest, oak woodland and through wetlands teeming with wildlife.
