The Lava Caverns is a location first introduced in Monster Hunter Rise.
This large cave system/Volcano is divided into a searing hot area with flowing lava, and a nice cool area with beautifully pure water. compared to all the other lava and volcano environments, the Lava Caverns are considered the most beginner-friendly and safest of them all. It would be a wonderfully mystical environment if it wasn't teeming with monsters...
