Let us take you to a dazzling underground lake close to Bonito, Brazil for an unforgettable experience. The Abismo Anhumas adventure is a guarantee of fun!

Located in the State of Mato Grosso do Sul, the crystal clear lake where we’ll go is inside a cave and can only be accessed by a 72-meter rappel. Once inside the cave, we’ll be able to swim, snorkel, dive and float, while enjoying the peculiar view of stalactites and stalagmites. This is an activity you can do even if you don’t know how to swim since you’ll be using a life vest.

Some important things to take into consideration:

  • The water in the cave is cold (18º), so we recommend renting a neoprene suit and bringing a light jacket.
  • Make sure to bring snacks to recover energy after the activity.
  • Only 2 groups of 8 people can join per day.

Abismo Anhumas is one of the most beautiful adventures in Brazil. So book your trip now and don’t miss the chance to participate in this unique experience.
