4° Track is a walking track in Fairfield, Lower Hutt. The linked site and the earlier text are a list of earthquakes near Lower Hutt, which does not describe a track, so they are not used.
The directory holds no details of the route, its length or difficulty, facilities, access, parking, dogs or children, and no visitor comments beyond the rating. It gives no figures for other tracks nearby either, so we can say no more about what it offers or how it compares.
