If you're starting off in the Skidmore / 33rd area, you can loop in the opposite direction of Kelly point.
Head South on 33rd to Marine, go East to the 205 path - head south to Prescott, exit path and meander over to 81st, head South to Fremont, go East to Rocky Butte. You can head back via Tillamook to the golf course, and then take Alameda back to your hood, or take Fremont back. If you have more time, do the hill twice or head South to Tabor for another climb.
This ride has a lot of the same offerings as your Kelly Point Loop, but has a little bit of a hill in the middle for interest.
