Kekuli sounds like our kind of place! We are mostly no-hook up folks. According to BC Parks web site it is a fairly new campground, probably why we never heard of it. It's on the list!
Two favorite places on the Olympic Peninsula are both county parks - Salt Creek near Joyce on the Strait of Juan de Fuca, and Dungeness. Salt Creek has some hook-up sites, but the best sites are amongst the trees, on a bluff overlooking the water w/ no hook-ups. Dungeness (no hook-ups) is my #1 favorite day trip to enjoy wildflowers, wildlife, smell the salt air and look at knock-out views of the Olympics. Stayed there 5 days last summer and walked a different trail nearly every day. (Just trying to entice you to visit the Peninsula again!)
Of course there are the campgrounds in the Olympic National Forest & National Park, they tend to be crowded in season. Mora is probably the best on the coast, its not actually on the ocean, but close to Rialto Beach, a spectacular beach in the park.
We had friends in a Bigfoot
stay a night in our driveway last week, they thought our place pretty spectacular! But we're not on the water or have great views! (just wildlife, trees & power hook-up!)
Not great shots - but good for enticing........( do look a little better larger)
