Not a big hike or anything. A lots of traffic noise but went on the weekday morning so not many people. Spotted many rabbits and flowers. Many people kayak around the bay. It was fun walk, some part is muddy.

Beautiful hike and would love to come back and try a different time of year but the water was too high to take the bridge and the mud was terrible leading up to it.

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....
