The hot springs is not hot. The water is cold when you jump from the boat. The tour doesn’t go down into the caldera.

Overall was a good experiment and worth the money. The transportation side of things was more challenging- we booked transportation through Viator and the bus was 30 minutes late to pick us up and the communication around this was not ideal.
