Trail is ok..make sure to put on bug spray lots of mosquitos all through out the trail.

This is a pretty area to walk through and is relatively flat throughout. Parts of the trail don’t have tree coverage, so it does get warm. There are a ton of mosquitoes on this trail! I rarely get mosquito bites, but I spent the whole walk trying to brush mosquitoes off of my husband and he still ended up with quite a few bites.

Nice trail not too far from the city. Wasn't too busy, with a good mix of scenery - old woods, swampy marsh, farm land. Great berry picking in the summer.

Not too heavily trafficked. It was fun to explore the Slough. not the prettiest of views with the highway and office park but, smooth easy kayaking and a fun few hours on the water.

Nice easy trail for a short stroll. Blue berries are a plus.

Really nice city park that makes you forget you are in Bellevue. Great for kids and dogs on leash. Makes you realize what the landscape was like before all of the development in the area. Very flat trail that really doesn't get very muddy.

We finished the water trail. 3.6 miles in less than 3 hours. It can be tough and tiring. But the scene is really rewarding and quiet.

Nice walking trail with abundant wildlife. The skunk cabbage is intriguing.

TONS of kids. Not sure if i just didn't do it properly but it was very uneventful. Nice for bird watching and scoping out different plant species.

Lots of different bird species all along trail and it's located in the middle of Kirkland suburbia so it provides a peaceful respite despite some of the street traffic noise. One can walk, run, or bike along most of the trail and it connects you to Juanita Beach Park which is especially beautiful in the summer.

This trail was very close to my Hotel in Bellevue and was a nice way to kill some time. It was a relaxing walk with historical markers along the way. I suspect it's a popular walk when Blueberries are in season!

A nice walk. Short and easy, great if you just want a little workout and don't want to drive too far

Great walk for little kids. Can use a baby jogger, plenty of room. Great boardwalks, bark trails, birds, dragonflies and other little critterrs. Park at the Winters House and walk the loop that passes the Boiler House sinking in the marsh. Highly recommended if you just need to get out of the house and not have to drive out to the sticks!

A nice short n easy walk in Bellevue. There are a number of interesting things to take a look at such as the old home off Bellevue way, a rotting pumphouse, the blueberry fields, a nice rhody patch, a nice bridge, some fun boardwalks, plenty of birds and a pretty good area of wetland. Mercer slough trail is a good walk for a dry winter day.
