Inspired by the gardens seen on a trip to England in 1910, William Douglas Cook returned home and began planting 160 acres. His brainchild became a stunning collection of more than 600 genera of trees from around the world. In spring and summer daffodils mass yellow, magnolias bloom in clouds of pink and white, and cherries, crab apples, wisteria, and azalea add to the spectacle. The main tracks in the park can be walked in about 45 minutes. Maps and self-guided tour booklets are available. Drive west from Gisborne center on Highway 2 toward Napier, cross the bridge, and turn at the rotary onto the Ngatapa–Rere Road. Follow it 35 km (22 mi) to the arboretum.
