Tips from the Community

Andrews Bay separates Bailey Peninsula from the rest of southeast Seattle and is a popular spot for swimmers, rowers, canoeists, kayakers, and paddleboarders. It's also home to various fish and wildlife, including junior and spawning salmon, bald eagles, ospreys, and more. It is a hot spot for boaters, especially during the summer, where you can see lots of pleasure crafts anchoring in the bay.

Excellent views, some areas are under renovation and lack signage. But nothing terrible. Very good experiences. A very ideal route for stopping and enjoying the views.

This park has three-quarters of a mile of water frontage on Lake Washington, and is mostly undeveloped except for a series of trails, some of which are paved for multi-use. You have great odds of seeing wildlife near the north and south ends of the park, and the park also has swimming, boating and fishing amenities.

This is part of the roughly 60-mile loop that circles all the way around Lake Washington; or you can divide it into northern and southern sections. Much of the total distance, including this stretch, takes place along the road.

The trail taking off inland here is the Hatchery Trail, which cuts all the way across the park's wooded interior. But the remains of the Seward Park Fish Hatchery, built in 1935, are actually visible from the main multiuse trail that continues all around the park.

The Freemont Bridge opens an average of 35 times daily to let boat traffic pass. It is the busiest drawbridge in the U.S. and connects the Freemont and Queen Anne neighborhoods. It is a great location to sit on the Burke-Gilman Trail and watch the boats go through this picturesque Seattle landmark

Seward Park at its finest

The original bridge, which was the first to access the island, opened on November 10, 1923. The task of opening the bridge for boats was given to George Lightfoot, the father of the Lacey V. Murrow Memorial Bridge on Mercer Island. It was dismantled and replaced in 1940. At this site, I-90 traffic is currently carried by two parallel bridges.
