Do you live in Washington and want to find secret swim spots your dog will absolutely love? You’re in the right place—keep reading to discover some tail-wagging adventures!
Washington is home to incredible swim spots where our four-legged friends can splash to their heart’s content, free from those frustrating ‘No Dogs Allowed’ signs.
Whether it’s a peaceful lakeside or a dedicated doggy beach, these six hidden gems offer the perfect getaway for you and your furry companion.
1. Lake Roosevelt’s Hidden Hawk Creek Cove

Tucked away near Davenport lies a pristine shoreline paradise that most tourists completely overlook. The shallow entry at Hawk Creek makes it great for hesitant doggy paddlers, while deeper waters await confident canine swimmers.
The surrounding ponderosa pines provide welcome shade during summer heat waves. I’ve watched my Retriever spend hours chasing sticks into these crystal-clear waters without another soul in sight.
Pack a picnic and make a day of it—there’s plenty of shoreline to claim as your own private dog beach. Just be sure to bring fresh water for drinking and a towel for those muddy paws!
2. Magnuson Park’s Off-Leash Water Wonderland

Seattle’s best-kept canine swimming secret sits right inside the city limits. The off-leash area at Magnuson Park features a fenced shoreline where city pups can safely splash without leashes.
Gentle slopes into Lake Washington make entry easy for dogs of all sizes. Your water-loving companion can socialize with other four-legged swimmers while you chat with fellow dog parents.
Summer weekends get busy, so arrive early to claim the best spot along the shore. The combination of grassy areas for post-swim zoomies and dedicated swimming zones makes this urban oasis truly special for Seattle’s dog community.
3. Marymoor Park’s River Dog Paradise

Redmond’s crown jewel for canine water enthusiasts offers a slice of doggy heaven along the Sammamish River. The 40-acre off-leash area includes river access where your pup can cool off after chasing tennis balls through the park.
In the summer, dogs often discover their inner fish, joyfully leaping into the gentle current over and over again. The river’s shallow edges provide safe wading for smaller or less confident swimmers.
Wooden benches along the shore let you relax while supervising your water-loving companion. The park’s convenient location makes it perfect for after-work splash sessions during those scorching summer months.
4. Luther Burbank’s Secret Shoreline Escape

Mercer Island guards this hidden gem where locals bring their four-legged swimmers year-round. The designated dog beach sits tucked away from the main park areas, creating a semi-private aquatic playground.
Smooth pebbles replace sand here, eliminating those post-swim gritty coats that plague other beaches. Lake Washington’s clean waters invite endless games of fetch with floating toys.
Free parking and bathroom facilities make this spot exceptionally convenient for extended playdates. Just watch for the occasional passing boat creating waves that might surprise your pup—though most dogs find these surprise swells absolutely thrilling!
5. Swan Lake’s Mountain-View Splash Zone

Kittitas County’s best-kept secret offers alpine swimming with breathtaking views. This high-elevation lake stays refreshingly cool even during August heatwaves, making it ideal for thick-coated breeds who overheat easily.
Fallen logs create natural fetch toys while the gradual shoreline ensures safe entry points. Pack your hiking boots—the short trail to reach this hidden spot keeps the crowds away and adds to the adventure.
We stumbled upon this gem during a camping trip when my Golden Retriever refused to leave the water despite the setting sun. The surrounding pine forest creates natural privacy screens between small beach areas, giving you and your pup semi-private swimming holes.
6. Wanschers Park’s Creek-Fed Swimming Hole

Lacey locals have kept this creek-access point hush-hush for years. The shallow creek flows into a beautiful natural swimming hole, perfect for pups who love to splash without strong currents or waves.
Overhanging trees provide essential shade during hot afternoons. The creek bottom’s smooth stones feel gentler on paws than rocky beaches, making this spot ideal for senior dogs or those with sensitive feet.
Limited parking keeps crowds minimal even on perfect summer days. Bring water shoes for yourself—the same smooth stones that please your pup can be slippery for human feet, but the crystal-clear water makes watching your dog’s underwater antics an absolute joy!
