A few weeks ago I made a post about the thermal hot springs in Pucón. Recently I visited an even better one called Termas Geometricas.
If you are in Pucón and fancy visiting a thermal spa then you will certainly be spoilt for choice. This particular thermal at Termas Geometricas is certainly one of the more popular ones, and one of the more expensive too (at around £30 per person). Having said that it is certainly worth the money and is one of my biggest travel trips if you're visiting Chile.
At the very end of the valley is a huge waterfall with another sign saying not to go in. This is where the ice cold water from the waterfall, and the boiling water from the springs meet.
It takes about ten minutes to walk through the whole park (and more if you take a dip in each spring) and seeing the waterfall is a great way to end the trip.
The hot springs themself are a mixture of water coming directly from beneath you, or water being diverted via tubes.
The structures and buildings here are totally at one with nature. You can see trees that have fallen over the walk ways, which are left as mini obstacles, or just to keep the park at one with its surroundings.
