At Eagle Point, just west of Paynesville, the Mitchell River enters Lake King in an unusual way: between long, narrow banks of silt that push far out into the lake. The shape was built by sediment dropped where the river slows, and it gives the place a strange, almost engineered look despite being natural.
You can view the jetties from Eagle Point Bluff, then continue along Point Dawson Road to get closer to the southern bank. It is a good short detour by car or bike, especially in clear weather when the lake, reeds, and river channels are easy to read from above.
