We had the best day at two locations in this park! First, we stopped at one of the first dune beaches just after the ATV staging area and beach. There was a pit toilet... very convenient. Luckily, the ATV area is separated from the walking, shelling, & playing area so I felt safe letting the kids roam around. When we arrived, a nice young lady (a new instructor at the dunes park) happened to be there and let our kids sandboard down the little dune. Each tried it three times (it was a first!) and it was the highlight of my son's trip. We had a fantastic time walking for hours, picking up shells of all sorts, running on the dunes, taking pictures, and finding agates and rocks. Then we went back to the car, got our picnic lunch, and drive a few more miles towards the jetty and parked where the crab dock is. Also a bathroom here. We noticed a little stretch of beach, then spotted a blue heron nearby. We decided to picnic on the little beach. We saw blue herons catching fish, harbor seals frolicking in the water, and clear blue skies. I was in heaven as we picnicked with peanut butter and jelly sandwiches and fruit. I've rarely encountered a more peaceful gorgeous interesting location. While my husband and the kids tried to find clams in the endless shallow waters (at low tide), I picked up my husband's photographer's camera for the first time and was inspired enough to take 175 digital photos. I even snapped a picture of the heron catching a fish. Beautiful! We were at Jetty park for about 6 hours but it felt like we could've stayed much longer and explored more nooks, beaches, and lookouts. Thank goodness we used sunscreen because the sun reflects fiercely off the sand on the dunes. Fabulous place!
