In the summer time, when the moon, earth and sun are aligned just so, the tides pull back just a little further to reveal a rarely seen world.
These days of extreme minus tides are the perfect time to discover and explore the intertidal world, where a remarkable community of sea life thrives. At the highest of the intertidal zones, crabs of every shape and color scurry among the nooks and crannies. Brittle stars cling to rocks verdant with algae. In the mid zone, moon snail egg casings litter the sand like broken pottery. Tiny geysers erupt from clams buried deep in the sand. At the lowest zone, live the mostly unseen legions—the nudibranchs, sea lettuce and tube worms that spend most of their lives submerged.
In Washington, you’ll find more than 50 state parks with saltwater beaches, from the mouth of the Columbia River, up the coast, in the San Juan Islands and throughout Puget Sound and Hood Canal.
Several state parks have interactive programs happening this summer, so you can learn even more about these magical margins between land and sea! Volunteers from marine education groups, such as Harbor WildWatch, the Seattle Aquarium and Puget Sound Estuarium, will be stationed at many state parks beaches this summer to teach visitors about the wonders of the intertidal zone.
Best of all?
No SCUBA certification is needed!” says Stena Troyer, a Science Specialist with Harbor WildWatch, based out of Gig Harbor.

So what is the best way to explore the beach? Stena Troyer of Harbor WildWatch says the best beach manners come from being a good GUEST!
G = GENTLE touching. Whether it’s sunscreen or Cheeto dust on your fingers, beach creatures would prefer you rinse that off and use just one wet finger to explore with. If whatever you are examining appears to be stuck, don’t try to pry it off. You might be breaking up some critters happy home!
U = USE your head — to measure rocks! Any rock you turn over on the beach should be no larger than what is between your ears. Turn gently!
E = EVERYTHING stays. Once you are done exploring under a rock, turn it back over carefully. Leave the beach at the beach. Take away only knowledge, memories, photographs and trash.
S = STEP lightly! The beach is a wet and slippery place and falling on barnacles is…uncomfortable. But moreover you don’t want to miss—or squish—any of the cool critters by running past them too quickly!
T = TAKE your belongings. If you brought it with you, take it home. If you find something that does not belong on the beach, such as trash, take that as well. Leave the beach a cleaner place than you found it.
There's more shore to explore! Summertime tides can hit extreme lows, exposing more of the shore than usual. Beaches like this one at Tolmie State Park are great places to get to know the intricacies of the intertidal world. Photo by Caleb White
