The lake Ozette hike is a must even for little kiddos, just be aware that it rains a lot at the beach camping can be very damp from the sea mist, plan the hike in the summer when you know the weather will be good, I did it back in the 70s when the archaeology dig was in full swing there, there are some fantastic petroglyphs on the beach about mid point, they don't advertise them so you have to search them out, kids will come away with a better understanding of native Indian culture, and the value of treasured historical sites, I went back a few years ago with my scout troop and the trail has been improved with much of it in board walk, the best camping locations were on the beach about 1 mile north of the upper triangle, drinking water is brackish so a filter is a must, and they require a bear canister and permit to enter, bear canisters can be picked up in Port Angeles at the ranger station, didn't see any bears but raccoon's and deer were plentiful, think there are 18 different Petroglyphs in all I found about 10.
