Endless rocky tidal pools and famous for the Tongue Point Marine Life Sanctuary! You could decide to camp at the County Park, with 90 campsites, sandy beaches, a playground and play fields and hiking trails to Striped Peak. Nearby Crescent Bay (watch for the signs) offers even more beach fun
Within the recreation area are the original bunkers that were once part of Fort Hayden during World War II.
Be ye not so dumb as MY family and forget to check the tides before you drive [ALL THE WAY OUT] here to see the tide pools. Major disappointment to discover there was barely enough room for all of us on the rocks without someone falling in, and no tide pools anywhere. Silly tourists.
Salt Creek gets five stars because 1) my family is dumb (see above) and everyone says this is a great spot to explore and 2) the enormous grassy areas for camping and picnicking and stretching your legs after that long drive. Thankfully we'd brought a cooler full of snacks and a soccer ball, so the day wasn't a total loss!
Our family visited here twice. Check the tide charts. (see website below) High tide is ok but, low tide is amazing! There is a lot of area to walk and explore if you take the second exit. The first exit takes you to the recreation area to camp, play, and check out the shore. The second exit leads you to a small parking area. It is much less crowded and has a vast shore line without as much climbing. We were able to see a large starfish, lots of little starfish, tiny crabs, small sea anemones, and tons of muscle shells. Be prepared to get there really early (low tide) to get the most out of your trip. This is the website that we used for finding low tides in Washington. http://www.saltwatertides.com/dynamic.dir/washingtonsites.html
Check a tide table before heading out. Minus tides are the best because there is an endless amount of tide pools chock full of sea anemones, crabs, sea stars, fish and other surprises! Invest in a Muddy Buddy suit by Tuffo (online or at Necessities and Temptations in Port Angeles) and bring boots so your child can scramble all over the rocks and in the water w/o you worrying. Bring band aids only because the rocks and the mussel shells can be sharp and you don't want to have to cut your adventure short and head back to the car. Bring a picnic lunch and a frisbee or basketball and plan to stay and play at the great playground and huge play field. It's also worth it to bring your camper or a tent to spend the night depending on the weather. One of the best places in the NW to check out tide pools and a beach without much walking or driving.
