Audio Guide of Abismo Anhumas

Abismo Anhumas can only be visited through guided tours organized by authorized agencies, with typical departures at 8:00 AM from downtown Bonito. Access is by 4x4 vehicle along a road of about 20 km, followed by a zip line or rappel descent; book in advance through Bonito's official tourism website for exact details, such as Visit Bonito.

The Abismo Anhumas tour costs around BRL 550-650 per person (approximately USD 100-120), and includes safety equipment, a certified guide, transportation from Bonito, and the descent. There is no free admission, as it is a protected ecological reserve; check updated prices at Bonito Way, one of the official operators.

It is recommended to allow at least 4-6 hours for the full tour, including transfer, the 72-meter descent into the cenote, and time for snorkeling or diving in its crystal-clear waters. If you are a beginner, allow a little extra time to get used to the activity.

Abismo Anhumas is an impressive natural sinkhole formed millions of years ago through geological processes in the Bonito region, with turquoise waters and a depth of up to 80 meters that make it an ecological treasure. It has no specifically documented Indigenous cultural meaning, but it represents the rich biodiversity of the Brazilian Pantanal and is part of the protected natural heritage of Mato Grosso do Sul.

The best period is the dry season from May to September, when the water is clearer and conditions are ideal for the descent. Choose morning tours to avoid intense heat and enjoy the natural light filtering into the cenote; avoid the rainy season (October-April) because of possible cancellations.

Unfortunately, it is not accessible for people with reduced mobility, as access requires a 72-meter zip line or rappel descent and walking on uneven ground. If you have limitations, check with operators such as Bonito Tourism for more suitable nearby alternatives, such as cave visits with less physical demand.

Near Abismo Anhumas, in Bonito, you can visit Blue Lake Cave, famous for its blue-water lake, or the Prata River for snorkeling in crystal-clear waters. Other options include Ceita Coré Farm for horseback riding; all are within 30 km and are part of the region's tour packages.
