This is a beautiful campground. We were in site 102. It was shaded, level and plenty large enough for our 32 ft class A motorhome. My only comment is that the showers had no curtain or divider between the shower area and the area where you left your shoes and clothes. I tried really hard to keep my things away from the spray, but my clothes and shoes got a little wet! We enjoyed looking for turtles in the slough and watching the birds. Lovely area!

Level cement sites makes setting up a breeze. Large multi lane dump station with freshwater fill.

Nice quiet clean campground.
I don’t yet own one but don’t agree with not allowing e bikes in the park. Some of us would enjoy riding a bike around but aren’t able to pedal anymore.
Also don’t see a problem with kids riding battery powered kick scooters with flashing lights, would rather see them out having fun than sitting around on electronics not enjoying nature.

This was a wonderful place to camp and explore! All the campsites were really nice, but the ones on the River were to close. We can't wait to go back!!!

Too many campers not following the quiet time policies and also dog s on leash policies. Seems the park ranger wasn't going to enforce either.
