As I'm reading the review, it seems some people are reviewing the one by the river which some "lanchas" stop over on their way to or back from Livingston. The one my friend and I went to was in Finca Paraiso, about a half-hour bus ride towards the "El Estor" direction. Just hop on any of the microbuses with the conductors shouting "El Estor" from outside. Tell them you want to get dropped off at Finca Paraiso. From there, walk a few hundred meters (trail is clearly marked) and you'll find the hot springs. No vendors, not too many people. When we went there, there were six of us travelers in total, and one local and his two children who were looking after us - where we should jump off from, where it's deep or shallow. Bring your own food/snacks if you're heading this particular hot springs. On your way back, just stand on the side of the road and flag down the next microbus you see heading towards Rio Dulce.
