From here head south ont he park road towards Marine Drive which you will follow south Past the Smith and Bybee Wetlands Natural Area. Feel free to explore the park and check out my seperate guide for this area as well.

Take a right here along the N. Marine path next to the main road. Feel free to check out the guide I have for Smith and Bybee Wetland area if you are interested in exploring this area before you move on.

Take a left here along the train tracks and head back towards Marine drive to continue East along Marine Drive.

This path follows Marine Drive along the shore of the Columbia to where I-5 crosses over it.

Here you will leave the trail as this part of the Columbia Slough Trail hasn't been finished yet. You will follow along a bike lane on Marine Drive to 33rd Street where you will reconnect with the path.

Here off of 33rd street you will reconnect with the Columbia Slough trail. Hop on it and continue eastward.

Here you will again leave the bike path and rejoin the side of Marine Drive for a short distance.

Cross the road here and rejoin the paved path.

This is the next section still left to close on the creation of the trail. From here you'll follow Marine Drive east to Troutdale around the Blue Lake Regional Park. You'll re-join a path when you see Blue Lake Road on the right.

Follow this path as it will get you off the road for a little while. I'm not sure if this path is considered the slough trail but its better than the road for a while until you pass the Troutdale Airport.

The path here turns into a bike Lane along Marine Drive. Follow this and Marine Drive around a bend and under I-85 to NW Frontage Road. Use the track included here as a guide.

Follow the bike lane along Frontage Road to NW 257th Ave heading south.

You are going to follow this road south along the bike lane on its side all the way south to Rte 26 (Mt. Hood Highway) where you'll head back west on SE Palmquist Road.

You will head west on this road past a few sports parks and across SE Hogan Road to where it becomes SE Roberts Drive. When you come to a Y take a sharp left to meet up with the Springwater Corridor Trail. This is the only part of this trip where there isn't a clear bike lane or path so be careful with traffic and perhaps stick to sidewalks if y... Moreou can.Less

Take a quick left here to immediately meet up with the Springwater Corridor Trail. From here you can head back towards Portland to the north.
