Perfect Basecamp for the Ozette day hike
The official National Park Ozette Campground is a very small campground right on the lake and next to the ranger station in Ozette, at the upper NW quadrant of the Olympic Peninsula.
The sites are all flat and pretty much open - you will definitely see your neighbors. The toilets are a bit of a walk away at the ranger station / trail head. There is a huge parking lot full of cars but no people as this is a big place to hike out and camp on the beach (about a 3 mile hike in to the closest camping) - if you hike on the beach, you'll need a backcountry permit which you can get at the ranger station (available when it is open or closed).
It was surprising to me, but there were deer walking around the camp while we were there. Don't leave your food out. We also found it to be pretty mosquito-y here compared to other ONP camping.
This is actually in the National Park, so you'll need to have a NP pass or pay the fee to register your car. Camping is first come - no reservations.
All sites have a fire ring and picnic table. There is also a water point. For showers, you can pay at the Lost Resort up the street.
If you're planning to do the 9 mile Ozette triangle loop hike, you'll want to check the tide table at the ranger station. Low tide was very early in the morning during the summer and you'll find yourself racing the tide to get around the heads if you don't leave early enough. If you do wind up on the beach at high tide, you'll have to use the upper trails which requires some ropes and steep hills to finish the hike. If you have kids, be sure to leave early enough. If the tide is low in the morning, recommend camping here and using it as your base.
