Lagoa do Bonfim is the largest freshwater lake in Rio Grande do Norte, covering an area of 9 square kilometers near the town of Nísia Floresta. It sits approximately 45 kilometers south of Natal, reachable via the BR-101 heading south to Nísia Floresta and then roughly 10 kilometers along local roads, which are paved to Nísia Floresta and a mix of asphalt and dirt thereafter. The drive from Natal takes around 45 minutes, making it a practical day trip from the state capital.

The lake is fed by groundwater rather than significant river inflows, which accounts for its notably clear water — on calm days, visibility extends to the bottom at considerable depth. Water temperature runs warm, consistent with the tropical Northeast Brazilian climate, with surface readings around 27°C. The lake's volume can reach approximately 80 million cubic meters during the high-water period, which runs from May through June; during drought periods this figure can drop by roughly half, so water levels vary meaningfully by season.

The character of the paddling here is defined by calm, clear water on a large open lake. Kayaking is a recognized activity on the lake, and boat rentals are available along the shoreline for those who do not bring their own craft. Catamaran tours also operate on the water. One safety note worth keeping in mind: the lake bottom drops away quickly in places, with depth increasing rapidly from the shallows — paddlers and swimmers should be aware of this abrupt change in depth profile.

The surrounding area includes other nearby lagoons, including Lagoa do Pium roughly 5 kilometers away and Lagoa Papari about 9 kilometers distant, which could factor into broader trip planning in the Nísia Floresta region. The lake also serves as a drinking water source for approximately 220,000 people through the Sistema Adutor Agreste Trairi Potengi, which underscores the importance of maintaining water quality. Wind from the southeast is typical for the region, and forecasts can show gusts that may affect open-water paddling conditions on this exposed lake.
