Three Mile Bay and Four Mile Bay form one of Lake Taupō’s seven designated swim-only areas, located south-east of the Taupō town centre along the lakefront. The area between the bays is protected from all vessel traffic under Department of Internal Affairs bylaws, with no boats, jet skis or other watercraft permitted inside the marked zone. This makes it one of the safest swimming spots on the lake. The Rotary Across the Lake Swim finishes at Three Mile Bay each year.

About 3 & 4 Mile Bays
The designated swim-only area lies between Three Mile Bay and Four Mile Bay on the south-eastern shore of Lake Taupō. It is one of seven such zones around the lake where vessels are completely prohibited to protect swimmers.
Boundaries are clearly marked with black and white banded posts on the shore and corresponding buoys in the water. The Taupō Harbourmaster enforces the rules. The water remains clear and fresh, typical of Lake Taupō, with seasonal monitoring by the Waikato Regional Council through LAWA.
The bays sit along the popular Great Lake Pathway, also known as the Lions Walk, which provides easy pedestrian and cycling access from the town waterfront. Roadside parking is available along Lake Terrace, and nearby Wharewaka Point Reserve offers additional facilities including toilets and BBQ areas.
