Ride 06 - Cedar River Trail

This trail goes along Renton-Maple Valley Road, then it splits towards the end. One leg goes to Maple Valley, another into the woods and ends at Landsburg Road.

Ride 05 - Snoqualmie Valley Trail

One of my favorite, maybe because I always ride it in the spring what makes it more fun.

Stats:

Around 30 miles of vell maintained wide trail converted from old railroad. Very flat and with many straight parts slightly inclined towards Snoqualmie. Good for any bike with wider tires than road bikes. There is loose gravel at some spots and can be very bumpy closer to Snoqualmie. My GPS showed 800 feet elevation gain between Carnation and Snoqualmie.
