For a charming city walk, find the Maitai River off Nile Street and follow the signposted walkway to the locals' favorite swimming spot - Girlie's Hole. Another good 45-minute walk traces Nelson's old water system up through the native bush to dams built in the 1870s. Go to Brook Motor Camp; there's a parking area by the dam, and the trail leads on from here. Within 5 minutes, you'll be in native bush and a quiet valley. There are steps and handrails on the trail.
If you'd like to walk with the birds, go along Motueka Sandspit and enjoy the views across Tasman Bay to D'Urville Island and Nelson City. This is an internationally important seabird habitat and is home to many varieties that come here to breed. (Please keep dogs away from the southern end of the spit.) It's part of the Motueka Walkway, which is detailed in a brochure available at the visitor center. Access the walkway from the end of Staples Street.
