Ginny's Reserve is a park at 329 Worcester Street in Linwood, Christchurch. The linked site and the earlier text describe Ginny's Christchurch, a guesthouse on Plunket Street in Barrington, which is a different business, so we have set both aside.
The directory holds no details of what this reserve offers, its paths, facilities, access, parking, dogs or children, and no visitor comments that refer to it. It gives no figures for other parks nearby either, so we can say no more about the reserve than its street and suburb.
