• Tackle & Baits

  Nothing we hold confirms whether access is permitted. The nearest mapped parking is half a mile away, so the last stretch is on foot. Toilets show in mapping about half a mile away. Barramundi and estuary fish want hard-bodied lures and soft plastics worked around snags and drains. Read any posted signs at the access point rather than assuming. Night access is frequently treated as a separate matter. Should this one be busy, Hukiwai Reservoir is 0.4 miles off. The position on Umi Reservoir is worth confirming on the day.
