This dive site, Calhaus, is located near Santos in Brazil and is known as a highly sought-after dive point within Laje de Santos. Divers access the site via boat, entering the water with a giant stride while the boat is moving. The dive is characterized by an exciting passage through an underwater tunnel, a unique feature adding to the site's appeal. Navigation is relatively straightforward once inside, following the tunnel's natural path.
Marine life is a highlight of Calhaus. Divers can expect to see turtles and stingrays frequently. Guitar sharks are also present, although sightings may not be guaranteed on every dive. The presence of these larger animals attracts other fish, creating a dynamic ecosystem. While specific fish species can vary, various reef fish are present within the tunnel and its surroundings.
The best time to visit is likely during the warmer months (October to March), when conditions are generally calmer. However, the dive site should only be visited when sea conditions are appropriate as it is described that conditions do not always allow the dive. Experienced divers are usually preferred due to the boat entry and potentially variable currents. It's crucial to check weather and sea conditions before heading out, and it's recommended to dive with an experienced guide familiar with Calhaus' unique characteristics.
