Successfully completing this Treasure Hunt yields substantial benefits including 3 Festival Points that contribute directly to your seasonal progression and 100 Forzathon Points for purchasing exclusive items from the Forzathon Shop. These rewards make the challenge particularly valuable for players looking to advance through the Series 7 content efficiently.

Your first critical step involves obtaining the 1977 Pontiac Firebird Trans AM, which serves as the designated vehicle for this specific challenge. This classic muscle car can be acquired through the Autoshow for 50,000 Credits or potentially found in Wheelspins. Proper vehicle preparation significantly impacts your success rate.

Implementing the recommended tune (320 877 273) transforms the Firebird’s performance characteristics, optimizing it for the Danger Sign jumps required in this challenge. This specific tuning setup enhances acceleration, improves suspension for landing stability, and maximizes jump distance potential. For players preferring custom setups, focus on upgrading the engine, transmission, and suspension while maintaining a balanced power-to-weight ratio.

Achieving 5-star ratings at Danger Signs requires understanding the scoring system, which evaluates distance, speed, and style. The runway Danger Sign near the Horizon Festival Mexico main stage often provides the most consistent results due to its long approach and predictable terrain.

Mastering the approach technique involves building maximum speed before the jump ramp, maintaining vehicle control during ascent, and ensuring proper landing alignment. Avoid common mistakes like approaching at awkward angles or failing to achieve sufficient velocity before launch. For advanced optimization, consider our Weapons Unlock strategies for similar challenge types.


The treasure chest resides within the dense mangrove forests positioned directly south of Playa Azul. This specific location requires careful navigation through winding paths and partially submerged terrain. The chest typically spawns near distinctive tree formations and visible landmarks.


Approach from the northern coastal road, following the river inlet that leads into the mangrove network. The chest appears as a weathered wooden container with visible glowing effects, making it detectable from moderate distances. Reference our comprehensive Complete Guide for additional navigation strategies in complex environments.

Efficient completion of the entire Fireflies Treasure Hunt typically requires 15-25 minutes for most players. Seasoned participants can optimize this to under 15 minutes through strategic route planning and mastered techniques. Common time-wasting errors include repeated failed Danger Sign attempts and inefficient treasure chest searching patterns.

Strategic planning involves completing the Danger Sign requirement first, then proceeding directly to the treasure location without unnecessary detours. Avoid the frequent mistake of attempting multiple Danger Signs when one successful attempt suffices. For similar strategic approaches, consult our Class Guide for specialized role optimization.

Upon locating the treasure chest, simply collide with it to claim your rewards. The chest will disappear, and your 3 Festival Points along with 100 Forzathon Points will be immediately credited to your account. This successful completion positions you perfectly to tackle the remaining Series 7 seasonal challenges with enhanced resources and progression momentum.
