Learn how to open the Lighthouse Trapdoor in Prospecting. Step-by-step guide to getting the key, and accessing endgame rewards.
If you’ve ever visited the lighthouse in Prospecting, you’ve probably noticed the mysterious trapdoor on the upper floor. It doesn’t open by default, and there’s no obvious prompt when you click on it. That’s because unlocking this hidden area takes a few extra steps. In this guide, we’ll show you exactly how to open the lighthouse trapdoor, where to find the required key, and what you can expect once you head inside.

Steps To Open the Lighthouse Trapdoor in Prospecting
To open the trapdoor at the top of the lighthouse, follow these steps:
- Go to the Volcano Island: Take the boat at Fortune River to reach Volcano Island. This area becomes available once you’ve progressed a bit in the game.
- Find the Key Inside the Volcano: Once you’re on the island, head into the volcano cave. The cave has multiple layers and lava hazards, so bring good gear. Inside, look for a metal key; it usually spawns near the center or edges of the lava pools. It may take a few tries or server hops, as it’s not always present.
- Return to the Lighthouse: With the key in your inventory, go back to the lighthouse near Fortune River. Climb up to the second floor.
- Open the Trapdoor: Interact with the trapdoor using the key. It should now unlock and open, letting you drop into the basement area.
What’s Inside the Trapdoor?
Beneath the trapdoor, you’ll find a secret chamber that is locked. However, there are 3 tables with ‘the Place Item’ prompt. You need to place the following three minerals on the tables inside the chamber:
- Uranium
- Catseye
- Flarebloom
Place each mineral on its designated table to unlock the secret maze area, where you’ll be able to claim powerful items like the Fossilized Sluice, Pan, and Shovel. These minerals are rare and can be found in advanced mining areas such as the Magma Furnace, Infernal Heart, Fortune River, Rubble Creek Deposits, and Volcanic Sands.
Tips for Success
- Make sure you have completed the 1st lighthouse quest.
- Keep Uranium, Catseye and Flarebloom in inventory.
- If the key doesn’t spawn, try rejoining a new server.
- Check the trapdoor area often; new secrets or updates are sometimes added here.
Opening the lighthouse trapdoor is one of the coolest hidden secrets in Prospecting. It takes a bit of effort and exploration, but the payoff is worth it for curious players and completionists. Whether you’re after loot, lore, or just like finding new areas, this is one spot you’ll want to unlock.
