How to Fish Map & Radar Guide: All Island Routes
How to Fish has no verified exact coordinate map: progress Island 1 to Island 5 in order, complete each boss-trophy hand-in to add the next radar marker, then steer toward the new circle. If you searched for a radio, the navigation item players usually mean is the radar.

Island map and unlock order
| Route | Unlock trigger | What appears next |
|---|---|---|
| Island 1 → Island 2 | Return the Spider Crab shell and receive the boat keys | First travel route |
| Island 2 → Island 3 | Return the Giant Piranha trophy and finish the NPC dialogue | New radar circle or route marker |
| Island 3 → Island 4 | Return Pufferfish's bone-exposed trophy to the seated NPC | Next coordinates or radar marker |
| Island 4 → Island 5 | Complete the Tuna and Albatross progression sequence | Volcano-island route |
| Island 5 | Complete the whale sequence and use the RHIB keys | Ending route rather than a sixth island |
How to use the radar and route marker
Finish the full hand-in
A boss kill alone may not unlock travel. Pick up the distinct trophy and complete the quest-giver dialogue.
Check for a new circle
Return to the boat and read the radar for the newly unlocked route circle or marker.
Steer toward the marker
Use the circle as the destination cue and make course corrections while travelling rather than expecting a static world-map coordinate.
Confirm the destination objective
After landing, read the active quest before spending money or using a progression bait.
Missing marker, lost radar, and navigation blockers
| Problem | Check next |
|---|---|
| Boss is dead but no circle appears | Find the distinct trophy, finish the NPC dialogue, and re-check the boat radar |
| Radar was lost after reload or an explosion | Players report a replacement for sale near the Island 2 shop signs or equipment display |
| You searched for a radio map | Radio and radar are different words; use radar when looking for the route-marker tool |
| An old island skip no longer works | Patch 1.0.5 fixed travel to islands before they were unlocked, so follow the current story order |
| The marker still does not appear | Save and reload once after verifying the trophy hand-in; no universal reset or exact spawn fix is confirmed |
FAQ
Is there a full How to Fish map with coordinates?
No authoritative exact coordinate map is verified. Use the story unlock order and the radar circles added after boss-trophy hand-ins.
Why did the next island marker not appear?
A boss kill is not always enough. Pick up the distinct trophy, finish the quest-giver dialogue, then check the boat radar again.
Can I replace a lost radar?
Players report a replacement for sale near the shop signs or equipment display on Island 2, but this location is community evidence and may be version-sensitive.
