I read a lot about the fervedouros and included Bela Vista as a must-see on my list. We were a family group of six (all adults, although kids can go too). It is indeed the largest of all and the deep center where you experience the floating effect is also larger - you can see a line around determining the area. There is a restaurant on site, which you won’t find in the others. However, this was not my favorite. I felt the bubbling effect in others more interesting. As for the color, all of them have the same light blue color. As for “warm” water, none of them actually has warm water; they are a little chill at first. The surroundings seem the same on all with banana trees and nice vegetation around, very nice secluded areas. Each one offers a little different sensation to the experience, so it is worth to visit them all and find out for yourself which one is your favorite.

JALAPAO region in TOCANTINS State, BRAZIL: wonderful place to be, the “FERVEDOUROS”, natural waterfalls, clean rivers and lakes, all unforgettable for ECOtourists and nature lovers. FERVEDOUROS as shown in the picture are a kind of fountain fed by the underground water. One can float around don't need to be a skilled swimmer .... it is a lot of fun!!! Water temperature is about 75degF. ROADS to go over there are in MISERABLE STATUS , if you can name this a “road” at all. My backbone was crashed down after the second day on the road and I have just survived the remaining days laid down in the car to reduce impacts and loaded with painkillers.
