We camped overlooking the Juan de Fuca straits which separate the Olympic peninsula from Vancouver Island. Very cold waters but kids were swimming in it anyway! Remember chartering a TSDY from Vancouver a few years back and chasing Orca whales for a day - I think we caught up with sea lions and dolphins! Salt Creek Park is a redeveloped old WW2 military camp and observation outpost with bunkers built with the Japanese threat in mind.
