Sure.

Probably one of the easiest and most beautiful, in my opinion is to do a ride along marine drive along the columbia River. You can catch it easily at Broughton Beach and ride out to Blue Lake Park, stop at the ladies room, and ride back to Broughton beach for 18+ miles.

It's an easy, flat ride, but may be windy.

A non windy ride that adds up to just about 18 miles is to ride along both sides of the Willamette Down town. Start at the marina by the south waterfront blocks, ride across the steel bridge, go along the east side esplanade, past OMSI to SEllwood park. If you take a left there and go up about 4 blocks you hit some nice little restaurants. Then return the way you came. Part of this is called the Spring Water corriddor, but only a little part. Mostly your riding along the waterfront park area on the west side, the Esplanade on the east side, and then up to SEllwood to mess around in antique stores and stuff before you go back. If you go up to Sellwood it's 20+ round trip.

I'm all for routes where I can't really get lost!

Have fun!
