[From Jennifer Davidson] - Diamond Head road is not good due to ice - 4 chains 4WD needed but not worth it. Coming from a local who lives at the bottom of the hill.
[From Tom Curran] - Went up today: we chained up at the lower parking lot and then on the way down took our chains off at the turn off of Mamquam Road. We were in a car with 4wd and good winter tires.
[From Leifka] - Road is good - plowed and just a little slippy past the chain up area. Lot is getting plowed meow, trail is filled in nicely from the lot.
