Gruta do Lago Azul Natural Monument

A unique and stunning ecotourism experience. Definitely a must see if you are anywhere near Bonito. I barely speak a word of Portugese but didn't feel like I missed much by not understanding the guide, the cave is amazing and the experience was great.

This cave is seriously amazing. It's advised to get on an early morning tour or better yet, the tour which starts about 8am so you'll be in the cave at the 830-9am mark which is when the sun shines through the opening at the right angle to light all the water up and you see the stunning blues!

There is a great gift shop with some great Brazilian made items and a small canteen for drinks and snacks. The toilets are actually amazing which was unexpected for the remote location of the caves (you'll need good transfers I recommend a private driver to help get you there on time). The road is gravel and if it rains it would be pretty impassable - not so many good 4wd car options here.

The tour is a short walk in the bush and then the 300 stairs down which are slate and abit slippery if it's rains. The guide was great and made a really great attempt at helping explain some complex rock formations/science in English.
There is just the one large cave you walk to the bottom but then just back out again. You won't be able to touch the water or anything. Wear hiking/sports gear.

This has been one of the most amazing places I have visited. To access the grotto you have to walk 10-15 minutes.

Stunning place with blue water inside a cave. There is a bit of trek to reach to the final spot. Overall it’s a nice place to visit to

Amazingly beautiful. You need to get there at right time with sun light and with great camera. I visited 8:00am and good take below photos.

Amazing tour in Bonito. Everything is very well organized.

Lovely experience that you should add to your Bonito itinerary. Note there is a special time of year early in the morning that you can see the cave in its glory, but it was still a site to behold. Note: the cave is very hot and humid!

Beautiful location. Very good guides who understand a lot of the geography of the place. The view of the lagoon is spectacular. Get ready to go down and then up a lot of stairs

crystal blue water and amazing nature

Amazing place! A work of art from nature, it is impressive.

I stayed in the Visitor Center while the tourists I was with went on tour. Small gift shop, big wait. Is not Russia.
