You can’t access the trail head that the directions take you to do to construction, wasn’t successful in locating a different access point

Easy, well maintained trail in the city. LOTS of mosquitoes this time of year. Usually not too bad otherwise.

Great local running trail if you can outrun the mosquitoes! Interesting and practically empty on a weekday morning. Construction is a bit annoying but you quickly forget about it when you leave the temporary lot.

great place to jog, well maintained trails, and pretty scenes. heavy bugs in areas but overall enjoyed. liked the wooden paths in areas.

We walked from Bellevue downtown about mile and half to reach this place. Less trafficked and flat trial. We have seen a blueberry farm and few parts of trail is mud road. But, it felt really good to walk on mud road as it has given some cushion and easy on legs. Lots of wooden path too. The other side of the trial towards Bellevue way NE or 112th Ave is closed for pedestrians due to road work.

Lovely trail, really nice Environmental Education Center-- easier to start by Education Center due to construction at other trailhead.

Nice trails to follow and educational signs along the paths. Markers too just Incase you are not sure which way you are headed. I took a good long hike with the kids and they were very tired at the end which made me happy.

Great easy trail. Others mention mosquitos but we didn't see any probably because of the time of year. Saw lots of garter snakes in the tall grass near the river.

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.
