The Thermal Spires is the first thermal biome the player will most likely visit and is one of the safest. The biome has many threats, most notably the Rock Puncher and the Cryptosuchus. The northern section has many trenches with a large supply of Harvesting Nodes, and contains many entrances to the Thermal Spires Caves.
The southern portion of the biome features more rugged and plateaued terrain compared to the rest of the biome. Sharing a border with the Tree Spires, flora such as the Tornado Plates, Blooming Raindrops, and Reaper's Wineglass thrive within the area, albeit to a lesser degree. In addition, Coral growths that are normally seen on the "branches" of Tree Spires flourish on the nearby Hydrothermal Spires as well. An entrance to the Koppa Mining Site can be found within a large crevice in the area.
