That is a tough one! I personally have found that Cleveland is the
tough part and Juniper the less tough part, but I can really see how
that wouldn't be true for folks who prefer not to ride on the street
with the rest of traffic.
The biggest obstacles are I-80 and Juday Creek. My personal
preference would be this route:

But if the rider(s) would prefer to stay completely out of traffic,
and the bikes tires aren't skinny racing tires, then maybe this way
might be worth exploring (though maybe not at night, unless you are OK
w. the possibility of dealing with NDSP, heh):

If/when the LaSalle Trail connects up to Darden, that will go a long
way to solving this puzzle. In the meantime, here's one longer route
that should be relaxing, except for an illegal left turn on Cleveland
followed by 30 yards of riding on its shoulder:

Good luck, and please do report back and let us know what you find
out-- I know a lot of other Castlepoint residents would probably like
to not have to drive (and park) so much!
Best,
