Southern Peak is a gym at 36 Ward Street in the Dunedin city centre.
The linked page is a photography gallery and the earlier text describes a walking route, neither of which is this gym. The directory holds no details of its classes, equipment, memberships, prices, opening hours, booking or parking, and no visitor comments beyond the rating. It gives no figures for other gyms nearby either, so we can say no more about what it offers or how it compares.
