Gave this trail a go this week in the early morning. Was a slower trail, with a lot of winding paths through the wooded areas. Pleasantly full of wildlife and flowers to view along the way. A great path for the casual pleasant morning. If you are looking for a path to get out and really move this path is not for you however, limited visibility and high pedestrian traffic make the slower pace a must for safety.

Beautiful trail, feels like your out in the country, but you are ridding through Vancouver between I-5 & 205. It is a little hilly but not to steep. Nice ride.

My 8-year-old son and I did this ride. We parked at Leverich Park and went east to the end of the trail then back to the west end and back to Leverich Park.
Most of the ride was great, but there are some unpleasant parts have kept us from repeating it.

Things that could be better:
The trail is very bumpy from Fourth Plain to Devine. I hope they repave this section.
The trail is kind of hard to follow between I-5 and Alki Road. The ride along and across Hazel Dell Avenue wasn't fun (too much traffic whizzing by and a difficult crossing).

Things that were nice:
The trail is very scenic west of Alki Road, through Leverich Park, and South of SR-500.
The ride east of Devine is enjoyable (and pretty flat)
We liked taking the bridge over I-5.

One more thing:
The trail is pretty hilly around SR-500, my 8-year-old needed a couple breaks (my wife and younger kid wouldn't like this part).

Today, I parked in the Leverich Park's northern parking lot and took the trail to the east. The trip was an easy 12.6 miles roundtrip. There are some up and down grades, but very manageable. In general, the area is rural and picturesque. There were a few streets to cross, but all had cyclist friendly crossings. Overall a great peddle! Next time I'll add the trail to the west.

Heading east to Alki Road review:

Beginning with a lightly forested canopy with Burnt Bridge Creek on your left, the trailhead opens to beautiful rolling hills. You'll see robins, blue jays, sleepy horses, chicken coops, barns, and cottonwoods along the way.

Greenway Access off NE Burton (East)
Heading west to E 18th St. review:

Look for Burnt Bridge Substation and head down 90th to 92nd Ave. Turn right at NE 19th Circle and park at the end of the street. This an excellent path for biking, skating, jogging, or walking. The smooth asphalt is also ideal for longboarding until reaching E 18th St., where it becomes too bumpy.

You'll see plenty of beautiful marshes and duck ponds. Along the ride, you'll be surrounded by giant towering metal creatures, suspending power lines. Listen for the hum of electricity flowing through their veins. There's a bathroom at N Devine Rd. for the epic journey ahead.
