The Index and fast-travel list name six islands: Starter, Jungle, Desert, Snow, Volcanic, and Fossil. Costs below come from two September walkthroughs that agreed with each other, plus quest text read off the screen. The experience was updated on October 2 and again on October 3, 2026. Re-read the NPC if a number on this page does not match.
Costs in order
| Order | Island | Coins | Also bring |
|---|---|---|---|
| 1 | Starter Island | Free | Nothing |
| 2 | Jungle Island | 40,000 | Nothing |
| 3 | Desert Island | 180,000 | Nothing |
| 4 | Snow Island | 900,000 | 3 Legendary fish from Desert Island, any weight |
| 5 | Volcanic Island | 4,000,000 | Frozen Crown Dragonfish, Frosttusk Seal, and Frostmaw Monster from Snow Island, any weight |
| 6 | Fossil Island | 15,000,000 | Ancient Trihorn Fish at least 1,200 kg, Stormblade Shark at least 2,000 kg, Lavascale Dragonfish at least 2,500 kg, all from Volcanic Island |
You cannot skip. Sail to the next island, talk to the NPC by the arrival point, and pay. From Snow Island on, the unlock is a quest. If you already hold a race or rod quest, cancel it or finish it first.
What to lock
Use the key icon in the satchel.
- On Desert Island, lock every Legendary. Snow Island needs three of any weight. White Tiger Soul needs three more at 1,000 kg or more.
- On Snow Island, keep one of each named Volcanic-gate species.
- On Volcanic Island, keep the three heavy species for Fossil Island. Azure Dragon Soul takes any Legendary weight. Give it the small ones after the gate is paid.
The 50-catch pity on an island guarantees a Legendary or better on the next manual catch. Auto fishing does not advance it. Weight is separate. A Legendary under 1,000 kg still fails the White Tiger turn-in.
Travel
The Boat Merchant sells boats and can set your respawn on the island you are on. Island names appear on screen after you sail a short way from the dock. A game pass adds portals back to islands you have already unlocked. The pass does not open a gate you have not paid.
Each island also has two boss spots. They are listed on the boss fish guide, not on the unlock NPC.
