Collecting Sea Glass at Rosario Beach, Fidalgo Island

Rosario Beach, Fidalgo Island

Lets keep this spot just between us... okay?

Rosario Beach is located on the south side of Fidalgo Island. It's a picturesque cove complete with tide pools, Native American mermaid legend and, of course, sea glass.

It's the perfect place for stroll on the beach, walk cool rain forest trails or to simply sit on the shore and enjoy the quiet beauty.​​ It is a little rocky, but still smooth enough to lay down a towel and relax by the sea.

If you visit on any non-summer day like I did, you will likely have the beach all to yourself.

Can you find sea glass at Rosario Beach?

This is an excellent spot for sea glass hunting. The waves are very small at low tide, so no real worry of getting too wet and that means you can keep scanning for beach treasure.​

You can see from the photos above that the beach is covered in driftwood. I brought home what amounted to an entire carry-on suit case of Washington driftwood!

Back to the sea glass... and I found several pieces which were frosty, smooth and wave-tumbled.

I found all of this sea glass within about thirty minutes! The largest piece is three inches long and most are quite thick. As you can see in the photos below, there was a selection of colors but nothing too rare on this visit. The blues are beautiful though!

The Maiden of Deception Pass

Be sure to check out the beautiful wooden statue of the Maiden of Deception Pass. One side of the carving is the maiden as a human, while the other side is when she was a mermaid.

The story pole tells the Samish tale of Ko-Kwahl-alwoot, who risked her life to save the Samish people from starvation. 

Ko Kwal Alwoot was a beautiful Samish Indian girl living in a village at this site on the land which is now known as Rosario Beach. Now, according to Samish legend, she will live in the water forever. They knew that the maiden of the sea was watching over her people.

It is said that if you sit on nearby you may glimpse Ko-kwal-alwoot's long, black kelp-filled hair streaming in the current just below the surface.

Rosario’s sweeping beaches and tide pools are among its most popular features.

Check out the tide pools - also known as the Urchin Rocks - where you may encounter barnacles, hermit crabs, chitons, mussels, dog whelks, starfish and anemones.

P.S. Movie fans might want to know that a significant scene from the movie Captain Fantastic starring Viggo Mortenson was filmed at Rosario Head in September of 2014.
