Still one way, South to north. Ranger I talked to said it will not reverse direction anytime soon.

One way, south to north. I like it this way, completing the loop for the one way blue Lisa killough trail. Often wide fire road-ish, but frequently narrows.

This trail should be marked as one way, from northwest to southeast.

Agree it's not very blue, but it's not really green either. Something in between, for green folks to become more confident on bluey turns.

Around the lake is a nice easy jaunt doable by anyone. However the last section is increasingly steep and will require your lowest gears

This is not a blue. Very wide walking path. It can't be called double track but not much a single track. Was a nice spin for dusk,. Very exposed and dry, not for a summer road. Worth it to get outside on your bike from the city but mostly flat smooth trail that does not seem to be built for bikers but rather runners
