Took my 14.5 year old pup on this trail. Peaceful. We turned around when it got muddy. Most everyone wore masks!

This is one of my favorite hikes in Seattle. It almost doesn't feel like you're in the city anymore and being able to hike on the water is wonderful! There's always a lot of wildlife so keep your eyes open.

The Marsh Island trail is very muddy. Bring appropriate shoes.

Nice hike. Some of the steps to observation piers could use maintenance, and Marsh Island was a bit muddy but not too bad.

Its great fun! Gentle walking on a somewhat spongy peat moss like path, with metal walk ways between the islands. Ducks and geese enjoy the surrounding water and the lilly pad flowers are in full bloom right now —- July 26th.

Extremely muddy on Marsh Island and my white sneakers were kind of destroyed. Either prepare rubber boots or choose a right day! But overall speaking, nice view of Lake Washington.

....not passable today eastbound farther than the middle of appropriately named Marsh Island. The sign by the bridge to the island said the trail was flooded. It was. As far as it went, it was a pretty walk... water lilies blooming, birds and butterflies....

Marshy island is muddy. Can’t get to the lookout or boardwalk without serious mud.

Scenic trip - great trail surface. Views of the lake are stunning especially on a beautiful Fall day. I could see it being muddy if it had recently rained. We combined this along with the Washington Arboretum trail which made for a nice long walk/hike.

Too muddy in some area. Walking through swamps is fine but for biking? No. Maybe in summer it will be better because the trail would be drier. Other than that, it has great lake view. I will come back again if it’s not so muddy.
