Best Beaches & Water in Seattle for Kids & Families

Looking for the best beaches & water activities in Seattle for kids? As coffee culture, tech hub, and the most beautiful backdrop in America, Seattle offers swimming, splash pads, and waterfront fun that families won't find anywhere else. Whether you're visiting for the first time or looking for something new, we've rated every option for age-appropriateness, stroller access, and value so you can skip the guesswork.

Not all beaches are created equal for families. Wave intensity, lifeguard presence, shade availability, and bathroom access make a huge difference with kids. We rate each beach for specific age groups — a great beach for teens may be terrible for toddlers. In Seattle, expect mild year-round but drizzly — pack rain jackets, not umbrellas. Pro tip: Pike Place Market is a must but go early before crowds. The best family activities are in Seattle Center, all walkable from the Space Needle.

Below you'll find our curated list of beaches & water activities in Seattle, WA — each with detailed age ratings (infants through teens), cost estimates for a family of four, and the practical parent details that matter: parking, stroller access, nursing rooms, and honest reviews of what makes each spot worth your time.
