The Sulphur Bay Walk is a 4.7km flat boardwalk along the southern shore of Lake Rotorua, running from the Government Gardens through the Sulphur Bay Wildlife Management Reserve to Motutara Point. The reserve is a 145-hectare DOC-managed bird sanctuary where more than 60 species of birds have been recorded, set against one of the most active geothermal shorelines in New Zealand — 28,000 tonnes of geothermal water enter the bay from the lake bed every day. Entry is free and the boardwalk is wheelchair accessible.

The Wildlife Refuge
Sulphur Bay is formally protected as a DOC wildlife management reserve — no dogs are permitted. The reserve’s 145 hectares provides habitat for a large number of wetland and shorebird species, including the weweia (NZ dabchick), banded dotterel, black-billed gull, and numerous species of duck and wading birds. The NZ dabchick is a nationally endangered species particularly associated with this bay, where it nests and forages along the geothermal margins.
The geothermal activity that makes Sulphur Bay hostile to humans actually benefits the birds — the warm water remains ice-free and nutrient-rich year-round, supporting a high density of aquatic invertebrates. The boardwalk allows close observation of the shoreline without disturbing the nesting areas.
The Geothermal Shore
Sulphur Bay’s name reflects its chemistry: the lake floor here releases approximately 28,000 tonnes of geothermal water per day into the bay, warming the water and loading it with dissolved minerals. The sulphur-tinged shoreline is visible along much of the walk, with steam rising from geothermal vents near the water’s edge in cooler months. The smell of hydrogen sulphide is present throughout — the unmistakeable geothermal scent that permeates lakeside Rotorua.
From the boardwalk, the lake surface shows the warm patches where geothermal upwelling occurs — areas of slightly different colour and texture visible on calm days. Looking back toward the city, the Rotorua Museum building in the Government Gardens provides the defining foreground, with Mount Ngongotahā visible behind it.
The Boardwalk and Route
The walk begins at the eastern end of the Government Gardens on Queens Drive and follows the lake shore east via a combination of sealed paths and boardwalk. The route is flat throughout — there is no significant elevation change over the full 4.7km. The far end at Motutara Point offers views back across the bay toward the city and Government Gardens. Most walkers turn around here and return the same way, making the full out-and-back walk approximately 9.4km.
“Walked this on a quiet weekday morning and had it mostly to ourselves. The bird life is genuinely incredible — saw NZ dabchick up close for the first time. The geothermal steam rising off the shore is eerie and beautiful at the same time.” — TripAdvisor visitor review
“A hidden gem. Most tourists don’t bother but the birdlife and geothermal scenery are worth every step. Go at dawn if you can.” — Google review
