Overview
Lake Union Park sits on the southern shore of Lake Union in Seattle's South Lake Union neighborhood, occupying roughly 12 acres of waterfront land that was once an industrial and maritime hub. The park is managed by the City of Seattle and serves as one of the city's most accessible lakefront public spaces, connecting visitors to water, history, and green space within easy reach of downtown.
The park's centerpiece is the Museum of History and Industry (MOHAI), housed in the historic 1929 Naval Reserve Armory building. Beyond the museum, the grounds include a freshwater swimming area, a restored wetland, a model-boat pond, and broad lawn areas popular with picnickers and families. Historic ships are frequently moored at the park's docks.
Lake Union itself is a working lake—you'll see seaplanes taking off and landing, kayakers, rowing shells, and houseboats in the surrounding water. The park functions as a comfortable vantage point for all of that activity, making it as much about watching Seattle in motion as it is about any single attraction.
Getting There
Lake Union Park is located at 860 Terry Ave N, Seattle, WA 98109. It sits in the South Lake Union neighborhood, approximately 1 mile north of downtown Seattle.
By Public Transit
King County Metro buses serve the South Lake Union area. The South Lake Union Streetcar (operated by Seattle Center) runs along Westlake Avenue and has a stop near the park—check the King County Metro and Seattle Streetcar websites for current routes, fares, and schedules, as service details can change.
On Foot or by Bike
The park is a manageable walk from South Lake Union's core and from the eastern edge of Seattle Center. The Westlake Bikeway, a protected cycling route, runs nearby along Westlake Avenue and provides a convenient approach for cyclists. Bike-share (Lime) docks are present in the area—verify locally.
By Car
Street parking exists in the South Lake Union neighborhood but can be limited, particularly on weekends and during events. A small surface lot is located near the park; paid parking garages are available in the broader neighborhood. Check Seattle SDOT signage for current parking regulations.
Things to See & Do
Museum of History and Industry (MOHAI)
MOHAI is the primary indoor attraction at the park, with permanent collections covering Seattle's history from Indigenous peoples through the dot-com era. It also hosts rotating special exhibitions. Verify current admission fees, hours, and closures on the MOHAI official website before visiting.
Historic Ships Wharf
The park's docks are home to vessels from the Northwest Seaport Maritime Heritage Center, including historic tugboats and schooners. Access to the ships' decks varies; check locally for scheduled open-ship events and tour availability.
Waterfront Activities
- Non-motorized boating: Kayak and paddleboard rentals are available from concessionaires on or near the park's shoreline (verify seasonal availability).
- Model Boat Pond: A small pond near the park's center is a favorite spot for children and hobbyists sailing scale models.
- Swimming: A designated freshwater swimming area is present; conditions and lifeguard hours vary seasonally—confirm before swimming.
Green Space and Walking
The park's lawns and paved waterfront promenade are open year-round. The loop around the park connects to the South Lake Union streetcar stop and broader neighborhood walking routes. Benches and picnic tables are available throughout.
Seaplane Watching
Kenmore Air operates floatplane flights from a base on the north end of Lake Union. From the park's waterfront, watching seaplanes take off and land over the water is a distinctly Seattle experience that costs nothing.
Food & Drink
Lake Union Park itself does not have a full-service restaurant on the grounds, though food truck and seasonal vendor presence can occur—verify locally before planning a meal at the park.
The surrounding South Lake Union neighborhood has a dense concentration of cafes, casual restaurants, and bars, mostly within a few blocks' walk. Options range from quick counter-service lunch spots catering to the area's tech workforce to sit-down neighborhood restaurants. Westlake Avenue and Dexter Avenue N are the main corridors for dining.
For a lakeside meal with a view of Lake Union, several restaurants are located along the Eastlake neighborhood's waterfront, a short drive or bike ride from the park. Verify hours and reservations directly with individual restaurants.
Practical Information
Restrooms
Public restrooms are available within the park grounds and inside MOHAI during museum operating hours.
Accessibility
The park's paved pathways and the MOHAI building are designed with accessibility in mind. Verify specific accessibility features—including parking and dock access—on the City of Seattle Parks website or directly with MOHAI.
Weather
Seattle's weather is famously overcast and mild. Summer months bring the most reliable sunshine; spring and fall are pleasant but expect rain. Winter visits are cooler and wetter, though the park remains open. Dress in layers year-round.
Park Hours
The park grounds are generally open daily. MOHAI and the Historic Ships Wharf operate on their own schedules—confirm hours on their respective official websites before visiting.
Emergency Services
Dial 911 for police, fire, or medical emergencies anywhere in the United States.
Safety
Lake Union Park is generally considered a safe, family-friendly public space. As with any urban park, standard precautions apply: keep valuables secured, be aware of your surroundings, and avoid leaving items visible in parked vehicles.
The waterfront setting means pedestrians should be mindful of cyclists on the promenade and of dock edges, particularly with children. Swimming should only be done in the designated swimming area, and water conditions on Lake Union can change—exercise appropriate caution around motorized boat traffic.
