The concrete boat ramp at Lake Monowai sits at the end of Lake Monowai Road in Southland, providing public access to this remote Fiordland lake.

The ramp underwent significant restoration work in early 2025, with Southland Fish & Game completing long-needed concrete repairs.

A new jetty was constructed alongside the ramp at the same time, improving safety and ease of boarding and unloading for all lake users. A vehicle and trailer parking area is available near the ramp, with overflow parking just before it.

Boaters should exercise caution near the shoreline, as submerged tree stumps remain from when the lake level was raised nearly a century ago for hydroelectric purposes.

Environment Southland's Harbourmaster team monitors the lake for additional hazards, so users are advised to stay alert and use the marked boat lane.
