Acorn Reserve is a reserve at 97 Fifield Terrace, Waltham, Christchurch 8023, rated 3.0 from 1 review. The reserve covers 2,344 square metres across two parcels of land, and the one review describes a quiet corner with large trees and a river just across the road. Small urban reserves like this are often best for a short walk, a quiet sit or a picnic rather than organised games. Large old trees can drop branches after strong wind, so it is sensible to check the canopy before settling under one. Rivers beside reserves can rise quickly after heavy rain, so keep young children close and stay back from the bank. Quiet corners are often most pleasant early in the morning or on weekdays, when there is less traffic on the paths. For people in Waltham, Acorn Reserve on Fifield Terrace is a quiet local place to stop near the river and the trees.
