The beaches in Washington are uniquely beautiful - especially out by the coast. Complete with sea stacks, driftwood, and views of the mountains, they offer the perfect place to just relax and unwind. Most people have already heard of Ruby Beach and the La Push beaches, but here are 15 hidden beaches in Washington definitely worth checking out:

1. Shi Shi Beach

Shi Shi Beach is almost something you would expect to see on a postcard. If you walk a few miles up to the southern end of the shore, you'll find Point Of The Arches - which consists of over 30 sea stacks, small caves and tide pools. Have you explored this otherworldly beach?

2. Rosario Beach

Rosario Beach is one of the many beautiful stretches of shoreline in Deception Pass Park. Located on Fidalgo Island, the small cove offers a sandy beach and plenty of tide pools to explore at low tide. It's also a fantastic place to find sea glass.

3. Point No Point (Hansville)

Located on the Kitsap Peninsula, Point No Point is home to the oldest lighthouse on Puget Sound. You can also find picnic tables here, as well as hiking trails, and phenomenal views of Mount Baker. You'll find some of the most spectacular seashells here, too!

4. Copalis Beach

Copalis Beach is a small town by the coast, with miles of shoreline for clam-digging and kite-flying. Iron Springs Resort offers popular lodging nearby, with cozy cabins on a bluff overlooking the beach. It's definitely one of the most picturesque hidden beaches in Washington!

5. Kalaloch

The Kalaloch stretch of the Olympic Peninsula is filled with tide pools to explore. Located between Ruby Beach and the Kalaloch Lodge, the coastline is home to marine wildlife (like sea stars), as well as a Tree Root Cave, which somehow stands even though the roots lead to nowhere, and there's no soil to help keep it alive.

6. Golden Gardens (Seattle)

Most people know about Alki Beach, but this park in Ballard offers another gorgeous place to relax by the water in Seattle. Bring a blanket to lay out in the sand, and you'll be able to enjoy views of Puget Sound and the rugged Olympic mountains.

7. Owen Beach (Tacoma)

Owen Beach is one of many reasons to love Point Defiance Park. On a clear day, the sandy beach on Puget Sound offers some of the most stunning views of Mount Rainier and Vashion Island.

8. Camano Island

Camano Island can easily be reached by way of car or boat. Located between Whidbey Island and the mainland, the island is accessible by taking State Route 532 over the Camano Gateway Bridge. They also have beachfront cabins available to rent for the night, as well as boat rentals if you're looking to head out on the water.

9. Dash Point (Federal Way)

Dash Point is another peaceful shore along Puget Sound where you can bring the family. The waterfront park also has easy-to-navigate trails, along with places to go picnicking and camping.

10. Double Bluff

One of the best things about this dog-friendly beach is that you won't need to bring a leash. Located on Whidbey Island, the shore offers a quiet place where you can walk with Fido for miles at low tide.

11. Ebeys Landing (Whidbey Island)

Ebeys Landing is a recognized historic site, set on a bluff overlooking Puget Sound. If you take the loop down to the beach, you can go for a relaxing walk beside the shore with views of the Olympic Peninsula, Strait of Juan de Fuca, Mount Rainier and the Cascades. It also boasts some seriously spectacular hiking trails!

12. Rialto Beach

Rialto Beach is another slice of paradise in the Olympic National Park. The coastline is lined with driftwood, tide pools, and you can even spot sea stacks covered in trees just off-shore. It's a Washington treasure that simply must be experienced.

13. Juanita Beach (Kirkland)

Juanita Beach is an idyllic spot along the shores of Lake Washington. Here you can go swimming, play volleyball, or just enjoy an old-fashioned picnic with friends. The possibilities are endless, really.

14. Dungeness Spit (Sequim)

At low tide, Dungeness Spit offers a refreshing beach hike up to a historic lighthouse. The natural sand spit is 5.5 miles long, and juts out from the northern edge of the peninsula into the Strait of Juan de Fuca.

15. Eagle Cove

Our roundup of hidden beaches in Washington ends with Eagle Cove, a quiet, sandy oasis on the southern end of San Juan Island. During the summer, the small cove is a hot spot for kayak-launching, picnicking, or just going for a nice cold swim.
