I found out about this campground by accident. It was late, and we couldn't get to Salt Creek Recreation area. It is right on the 101 freeway, and very easy to pull into. I camped there in September 2008.
Describe your camping trip:
The campground is on a salt water bay, "Sequim" means "quiet waters". It is in the rain shadow on the North Olympic Peninsula, so it gets only half the rainfall of other Puget Sound locations.
Pros: They have a picnic shelter, nice restroom, coin showers, a boat launch, and hook ups if you own an RV. The view of the bay is beautiful.
Cons: Since it is so convenient, you get the lovely campers who like to breeze in at 1:30 am scraping their camper as they try every campsite left in the camp. That is an example that happened. Lots of one-nighters. Only one bathroom per loop, and there are two loops. The lower one is open during the off season months.
Nearby attractions: Port Los Angeles, Forks, Hoh rain forest, Olympic National Park, Dungeness Recreation area, Neah Bay.
Further comments: The camp hosts are friendly, and the campground is clean.
