In Forza Horizon 6, the Radio Towers and Legend Island Circuit represent some of the final exploration milestones in the game. They are not immediately available during the main campaign and instead serve as endgame unlocks tied to your overall festival progression. Once unlocked, they significantly expand the playable map and complete key parts of the Discover Japan system.

This guide breaks down how to reach them, what you need to unlock them, and why they matter for full map completion.

What the Radio Towers and Legend Island Actually Are

Most of the map in Forza Horizon 6 opens naturally as you progress, with 73 out of 75 landmarks available during normal play. However, the Radio Towers zone and the entire Legend Island extension remain hidden until you reach the final stage of the Horizon Festival.

These areas are designed as endgame content. They are not just cosmetic map markers—they also connect to progression systems like stamps, XP gains, and completion tracking in the Discover Japan system. Completing them is also tied indirectly to unlocking high-value rewards such as Barn Finds.

How to Unlock Radio Towers and Legend Island

Unlocking this final map region is not about exploration—it is about progression through the main campaign.

First, you must earn the Gold Wristband. This requires completing all major event categories across Japan, including:

• Road Racing events
• Street Racing circuits
• Dirt championships
• Cross-country competitions

Once these are completed, your festival progression will push you toward the final story sequence.

Next, you must complete the Horizon Legend Event. This is the seventh and final wristband milestone in the campaign. It acts as the true “ending” of the core festival journey.

After finishing this finale, the game removes the final map barrier and permanently unlocks Legend Island. At that moment, the Radio Towers and surrounding routes become fully discoverable on the map.

What Changes After Unlocking Legend Island

Once Legend Island is accessible, the game effectively opens up its final exploration layer.

One of the biggest additions is The Goliath, a massive perimeter racing circuit designed for high-performance R-Class vehicles. It runs across a large loop of the island and is considered one of the most demanding long-distance races in the game.

At this stage, you can also finish any remaining discovery progress, including missed landmarks and collectibles. This is where completion-focused players usually aim for 100 percent map coverage.

Tracking Your Progress and Collectibles

Because Legend Island unlocks late, many players use external tools to finish cleanup efficiently. Community maps are especially helpful for tracking missing landmarks and Radio Tower-related discoveries.

Useful resources include:

• Interactive landmark tracking tools like MapMaster

• Community-driven full completion maps and discussions

These tools help pinpoint exact locations so you can efficiently finish the final missing areas without driving randomly across the map.

Why the Radio Towers Matter

The Radio Towers are more than just map decorations. They act as progression markers that signal you’ve reached the final stage of exploration. Combined with Legend Island, they complete the game’s intended exploration loop and tie together the Discover Japan system’s reward structure.

For completionists, unlocking them is essentially the final “checkmark” before the game is fully cleared.

The Radio Towers and Legend Island are designed as a reward for full campaign completion in Forza Horizon 6. While most of the map is open from early on, these final areas give the game its true endgame identity—fast cars, long circuits like The Goliath, and full completion tracking for dedicated players.

If you’re aiming for 100 percent progress, unlocking this region is the point where the game finally opens everything at once.
