How to get Cavecrawler Wood (Blue Wood)

Take the ferry to the Tropics, then follow the Maze to the Cavecrawler Cavern.

Blue Wood is Cavecrawler Wood: the glowing blue trees deep under the Tropics. Its planks sell for $35 per unit at the Wood Dropoff, but a ferry ticket costs $400 each way and the black walls can block your route.

Pack before boarding

  • A truck with room for thick logs. Large pieces are heavy enough to stop it climbing steep slopes.
  • A Work Light, or headlights for the dark tunnels: press L on a keyboard, or tap the lights button on mobile.
  • An axe: the Cave Axe specializes in Blue Wood, with 32.72 damage per second. The Bird Axe does 9.75; otherwise take a Rukiryaxe or Many Axe.
  • At least $800 if you plan to take the ferry both ways.

From the dock to the trees

  1. Board the ferry at the Main Biome dock with your truck and buy a ticket.
  2. After reaching the Tropics, drive to the Maze entrance on the south side.
  3. Follow a route that matches the black walls in your server. The maze also leads to Fine Arts and a Safari exit; those are not the Cavecrawler Cavern.
  4. In the cavern, cut manageable pieces and leave enough room to turn the truck. If it stalls on a slope, reduce the load.

For help matching the walls, open the Cavecrawler Mapper. Compare it with the walls you can see before committing to a route.

If the run goes wrong

A black wall blocks the path
Try another route that matches your server. The wall pattern changes, so a fixed sequence from an old video can lead to a dead end. If every way into the cavern is blocked, save the trip for another pattern rather than forcing your truck through.
The cavern has no trees
These trees take about 5 hours 20 minutes to fully grow. A public server can have its stock cut down before you arrive; an empty cave does not mean you took the wrong entrance.
The trunk will not fit the mill
A Sawmax 01 can take many branches, but a Sawmax 02 is recommended for the thicker trunks. Cut oversized pieces smaller before feeding your sawmill.

Bringing it home

You can return on the ferry, paying another $400. There is also a Safari Exit Hole inside the Maze that teleports players, loose items and wood to the Safari Hole. That shortcut is for wood and loose items; do not plan on driving a truck through it.

Mill before selling: an unprocessed log pays only $5.1 per unit. Gold Wood pays $36 per plank unit and grows in the Swamp, so blue is not automatically the best cash run. Choose it for the glow, the building colour, or a trip whose ferry and maze costs you can afford.

The region map shows the Tropics and Safari in relation to your base. For a specialist on the Volcano rather than in this cavern, see the Fire Axe.
