The Lava Trail, also known as Lava Ravine or Magma Trail, is a hidden anomaly deep within the Underground Grove and is the inline trail of the Volcano.

The trail is merely the result of the wide vertical walls of the Volcano, then the sloped angled walls. The trail does not circle around the Volcano. It stops at a complete end with a brown wall with a small ramp going upward. This is one out of two locations where the player can access the Green Box, the other being the Lava Cavern.

This location is considered the most dangerous out of all in Lumberland, as there is no way out of the health-depleting zone. If the player wishes to go out, he/she must reset or leave the game to return back outside.
