Danger - Tres Marias - The guys that work in the port and cargo ships call it "Hawaii" and it is important to remeber that this is a very dangerous wave and can produce some giant series after series killers that will push you back to shore like a tsunami! So you must always have caution and rescue boats around.

Additional Info - Tres Marias - Cassino beach ("praia" in portuguese) is located in the city of Rio Grande, in the south of Rio Grande do Sul state. The city has one of the biggest ports of South America and is very close to the conection between Lagoa dos Patos (one of the largest lagoons in the world) and the Atlantic Ocean. If you look in Google Maps you will be able to see two fin lines that goes from the shore into the ocean called "Molhes" in portuguese... in the tip of the left one (Molhe Oeste) is where the magic happens! This stone barrier has a little wind-cart (a mine cart with a sail) and you can take it to go to the end of the Molhe, more than (4km long). Along the way it is possible to see sea lions and wolves hanging out in the rocks (those guys really know the best spots!) and sometimes dolphins.
