A great spot! There are a handful of pull offs, signed along the road as “Parking”, north of the designated campsites. You are fairly close to the road, but visibility along the HWY is excellent so parking next to the water feels quite safe. Traffic dies down at night and it’s otherwise very quiet. No trains while I was here but a riverboat passed in each direction. Beautiful and peaceful—I stayed nearly 24 hours. 3-4 bars VZN LTE.
