Gas Works Park

From Gas Plant to Gathering Place

The Seattle Gas Light Company's gasification plant ran for 50 years before closing in 1956, leaving behind a sprawling industrial site on the north shore of Lake Union. That site eventually became Gas Works Park - a 19.1-acre public space that blends industrial heritage with open green space in a way no other park in the country quite replicates.

What you're looking at when you walk through Gas Works Park isn't just an interesting backdrop - it's the only surviving coal gasification plant in the entire United States. At the industry's peak, there were roughly 1,400 such plants operating across the country, and this is the only one that could be documented with most of its generating equipment still in place.

When the park opened to the public in 1975, landscape architect Richard Haag made a bold choice that would forever change urban park design - instead of demolishing the old industrial structures, he preserved them. This decision transformed the space into one of America's most distinctive parks.

What You'll Find There

Strolling through Gas Works, you can't miss the massive metal towers and industrial remnants that dominate the landscape. They've been carefully cleaned and painted, with some incorporated into a children's Play Barn area where the past meets playtime. The Play Barn was originally the plant's pump house, built around 1910, and most of its original equipment is still inside - pumps, compressors, and piping included. Just outside, one of three smoke arrestor hoods originally installed in 1935 has been refurbished and repurposed as a climbing structure for kids.

The adjacent Picnic Shelter was the plant's boiler house, and at the eastern end of the building you can still see the tubes from one of the original boilers - a surprisingly striking piece of early industrial technology that most people walk right past.

Need a better view? Make your way up The Great Mound - affectionately known as Kite Hill by locals. This artificial hill was created from excavated soil and offers panoramic views of Lake Union, Seattle's skyline, and on clear days, Mount Rainier in the distance. At the very top, a sculptured sundial made by Seattle artists Chuck Greening and Kim Lazare invites a bit of participation: cast in concrete and inlaid with rocks, shells, glass, and bronze, it works by having you stand at the center yourself, with your own shadow acting as the gnomon to indicate the time of day and current season.

Things to Do

Gas Works has become a favorite spot for spreading out a picnic blanket, launching colorful kites into the breeze, or simply relaxing with friends. If you're in Seattle on the Fourth of July, this is prime territory for watching the fireworks illuminate the sky over Lake Union.

The Burke-Gilman Trail runs along the northern edge of the park, making it easy to incorporate a visit into your bike ride or walking route. The expansive grassy areas provide plenty of room for impromptu frisbee games, yoga sessions, or just lounging with a good book. Kids particularly enjoy the playground with its unique equipment, and on some days you might catch the rhythm of community drum circles or local musicians adding a soundtrack to the scenery.

The Views Are Everything

The 360-degree vistas from Kite Hill are impressive. From this vantage point, you can take in downtown Seattle, the iconic Space Needle, and the constant movement of boats and seaplanes on Lake Union.

If possible, time your visit for sunset - the view of the fading daylight over the water with city lights appearing is particularly nice. It's no wonder photographers consider this one of Seattle's premier spots for cityscape photography, regardless of when you visit.

Good to Know Before You Go

You'll find free parking for up to four hours in the spacious lot. Restrooms are available and typically well-maintained, although they close around 9 PM. During busy times or special events, you might see additional portable toilets.

Feel free to bring your four-legged friends - the park welcomes dogs, and you'll see plenty of people walking their pets along the paths and open areas. If you're traveling by bicycle, the Burke-Gilman Trail provides direct access to the park.

A Note on Environmental Awareness

Despite its lakefront location, swimming and launching boats are prohibited here due to contaminated sediments - a lingering reminder of the site's industrial past. Ongoing environmental remediation work continues to address this legacy, balancing historical preservation with ecological responsibility.
