Mountainside

The Mountainside grants access to Birch Wood, Lava wood, and Oak Wood. It has lots of Rocks and Cliffs making it challenging for any vehicular objects going along the gravel path. This biome includes a special area - The Volcano Obstacle - where the player must traverse a course of challenges to arrive at the Lava Wood place.

To arrive at this obstacle, the player must simply follow the gravel road.

The generally accepted 'end-game' moneymaking strategy involves this area. The player drives a road-train up the mountainside, until reaching the area outside the volcano. The player leaves the road train behind at the entrance to the volcano and drives up with a truck.

The player then harvests any amount of wood (One medium-size tree will fit in a basic truck and two small trailers, or a basic truck and a large trailer, or a large truck and a small trailer.) and then pushes the wood over the side of the volcano overlooking the area that the road train is parked on.

The player then drives down, hitches the road train, and collects the wood.

The recommended sawmill is Sawmax 01, but some logs are too thick for the 01 and will require the Sawmax 02 to harvest.

On rare occasion, some logs cannot fit into the Sawmax 02. Since the Sawmax 02's feed hole is wider than tall, a small fix for this problem is to cut the log into smaller chunks then turn it with rings facing up and down; this will allow the smaller chunks to pass through.

This "Hidden" person in the game is found on the mountainside, but to access him you must traverse up the volcano and proceed right, opposite of the swamp. You have a chance of him still being there if he is not taken or killed by a person [fixed]. The only importance he has right now is that he will talk about Gusmanak but won't tell you.

Swamp Bridge
Hidden near the volcano is a piece of terrain darker than the rest of the area (As of November 2015, it is no longer darker than the surrounding terrain). This piece, if hit with dynamite, will fall and roll into place as a bridge, allowing the player to bring a truck and trailer to the Swamp Area. Read more here.

Rock Bridge Cave

The rock bridge cave is hidden under the rock bridge, it contains almost nothing exept trees growing in the cave fron time to time. It may have something to do with the Volcano Obstacle or the River Tunnel in the future. Bao the panda was located in this cave during the Kung fu panda 3 movie event.
