Gruta do Lago Azul, Bonito

4.6
Gruta do Lago Azul enjoys a reputation for its deep blue lake and numerous fossils of large prehistoric mammals, including giant sloths and saber-toothed tigers. Local indigenous people discovered the entrance to the cave in 1924, and were probably the first to set foot inside. The underground lake is over 60 m (200 ft) deep, but the subterranean river that feeds it remains undiscovered to this day. See how the blue water twinkles when touched by the sunlight streaming from a hole in the ceiling.

  • The Gruta do Lago Azul was a show for the end of the trip. One of the famous for being famous among tourists, I recommend organizing the trip in advance not to be left out. About of 1 hour and have to have available are 300 steps inside the cave until you reach the Lake. Good take small backpack to get down with water, otherwise they don't get bottle in hand.

  • Unique place. Not all guides speak English. Definitely worth a visit.
  • No english speaking Guide and too expensive.
  • Very small cave. No English guide. Didn't like it.
  • The Gruta do Lago Azul is about 1 hour drive from Bonito, mostly dirt road (translation: bumpy ride). It is a very beautiful cave with plenty of stalagmites (^) and stalactites (v). From the reception area there is a short hike to the entrance of the cave and then one descends steps that have handrails except in a few spots. At the bottom one can see the lake and its beautiful blue water. Best time to go: from mid-november to mid-february there is a time when the sun hits the late directly. Usually around 8:30-9:00 AM in the morning. These are the most sought after spots for the cave and I believe one needs to setup a visit at these times months ahead. Tip: Apply plenty of insect repellent on exposed skin. Some women obviously knew about this and came with yoga pants and long sleeves which are an excellent way to defeat the mosquitoes
  • I stayed in the Visitor Center while the tourists I was with went on tour. Small gift shop, big wait. Is not Russia.

Where to stay in Bonito

The main town in Bonito provides a good range of accommodations to suit diverse tastes and budgets, with everything from luxury resort-style hotels to backpacker-friendly hostels dotting the gridded urban area. Heading east out of the main town, a few remote pousadas (guesthouses) lie along the course of the Rio Formosa. Pre-booking is essential, particularly during peak season (July and December to March), because of the relatively small number of options available for an ever-growing demand.
