What is the cleanest beach in Bombinhas? Mariscal or Conceição?

The Santa Catarina destination has gained national fame for its transparent waters and preserved strips of sand. But, after all, among so many options, which is the cleanest beach in Bombinhas and which offers the best cared for experience? Two candidates stand out: the long seafront of Mariscal, known for the structure and vitality of the open sea, and the more reserved refuge of Conceição, a corner of tranquility surrounded by nature. Both carry the Blue Flag seal, an international recognition that reinforces their environmental quality and unique beauty.

In this comparison, we will analyze how each beach differs in water preservation and quality. Find out below which one may be the best choice for your next swim in the sea.

Effect of vegetation and preservation of slopes

The native forest that surrounds the coast plays an essential role in maintaining the ecosystem. In the protected corner of the Conceição cove, for example, the green cover of the slopes acts as a natural barrier against erosion, preventing sediments from being deposited in the sea. Thus, the sand remains clear and the water clear, reinforcing the feeling of preservation.

On the Mariscal coastal strip, even with the characteristic of an open and extensive coast, the nearby green areas help to reduce the impact of urban occupation. In addition, the constant renewal of ocean water contributes to the bathing ability remaining satisfactory for most of the year. Consequently, both the most reserved corner and the open sea beach share the same strength: the natural protection that guarantees a quality sea.

These natural elements help explain why both remain among the cleanest strips of sand on the coast of Santa Catarina.

Comparison between the two

The cove of Conceição conveys a feeling of exclusivity, surrounded by hills that reduce the influence of winds and currents. For this reason, the sea tends to be more stable and usually maintains calm waters for much of the year. The coastal stretch of Mariscal offers spaciousness, infrastructure and space for sports and leisure. Although the sea is rougher in some stretches, many points maintain excellent quality for bathing.

General data on bathing in SC

According to the monthly reports of the IMA/SC (Institute of the Environment of Santa Catarina):

Source: Monthly bathing reports – IMA/SC, April to August 2025.

In general, bathing in Santa Catarina remained between 78% and 79% in the months of April and May. In June, there was a drop to 59%, followed by a partial recovery in August with 69%, showing that seasonal and environmental factors have a marked impact. These results reinforce that certified and monitored beaches continue to offer good conditions, although variable according to weather conditions.

Which one is cleaner?

The two strips of sand in Bombinhas meet the standards of the Blue Flag but have different characteristics. The protected corner of Conceição usually maintains greater constancy in the transparency of the water, thanks to its location surrounded by hills and vegetation. The long strip of open sea of Mariscal combines good bathing quality with complete infrastructure and space for different uses, although it suffers small variations in some sections.

Thus, the choice depends on the profile of those who visit the city. For those looking for tranquility and calm waters, the preserved cove is the ideal option. On the other hand, those who prefer spaciousness, support services and versatility find in the extensive ocean beach of the region a more advantageous alternative.
