The best secret locations in Forza Horizon 5 are tucked inside Guanajuato's tunnels, above La Gran Caldera, behind breakable scenery, and inside showcase events that quietly double as pop-culture museum pieces. On PC, the fastest way to uncover them is to combine a high-clearance off-road car, Drone Mode, Horizon Adventure progression, and a willingness to leave the racing line completely behind.
This isn't a list of random map clutter. These are the places and Easter eggs that produce cars, Accolade points, XP boards, unique photo opportunities, or the kind of “wait, how did I never see that?” moment that makes Horizon Mexico work. Before hunting, make sure your map filters show Bonus Boards, Barn Finds, Landmarks, and Horizon Festival sites. You can also check the official Steam page for Forza Horizon 5 before jumping in.
Guanajuato's tunnels hide more than shortcuts
Guanajuato is easy to treat as a street-racing playground, but its underground roads are one of the map's densest secret-hunting zones. The city contains multiple connected tunnels, steep stair-like streets, tight plazas, and entrances that can be missed when you're focused on a checkpoint. Several XP and Fast Travel boards sit in awkward positions around the city and its tunnel mouths, so a normal car route rarely reveals everything.
Start at the main Guanajuato festival-side roads and switch to Drone Mode. Fly slowly around the upper streets, then trace every tunnel entrance rather than driving directly to the next race. Drone Mode is particularly useful because the camera can pass through turns before your car commits to them. Look for blue XP boards mounted against walls, tucked under elevated streets, or placed at the end of a short tunnel spur.
The safest vehicle choice is the 2021 Ford Bronco or another responsive AWD build. Hypercars can reach the city quickly, but their long braking distances make Guanajuato's hairpins frustrating. For smashing boards, approach square-on and use rewind if a wall catches your front corner. You don't need a perfect drift; you need a clean angle.
| Guanajuato target | Best approach | Reward | Why it is easy to miss |
|---|---|---|---|
| Tunnel entrances | Drone Mode reconnaissance | Shortcuts and board routes | Buildings hide the road openings |
| City XP boards | AWD car with precise braking | 5,000 XP per board | Boards sit above or below the racing line |
| Stair streets and plazas | Bronco or rally car | Accolade progress and photo spots | Low-slung cars scrape and lose momentum |
If Guanajuato is hurting your frame rate, especially at night or during heavy traffic, the city is also a useful PC benchmark. Reflections and environment texture quality matter more here than they do in open desert. Our PC crash and FPS troubleshooting guide covers the same basic checks that help with Horizon 5: updated drivers, a sensible frame cap, and avoiding unnecessary background overlays.

The volcano is more than a dramatic backdrop. At the summit of La Gran Caldera sits the Gran Telescopio, a landmark that becomes a standout location for EventLab thumbnails, Forza Horizon 5 photography, and seasonal challenges requiring a high-altitude setting. The road up is rough, winding, and full of loose-surface corners, which makes it a much better test of car choice than a straight-line sprint.
Use a rally-tuned AWD car with moderate suspension height and off-road tires. The 2020 Subaru WRX STI is a dependable choice, while the 2018 Can-Am Maverick X RS Turbo R is even better when you want to cut across the volcanic dirt instead of following the switchbacks. Keep throttle inputs smooth. Over-rotating on the hairpins usually sends the car into the outside rock, and rewind is slower than simply entering the corner one gear lower.
The telescope itself is also a reliable place to complete photography tasks involving the volcano, observatory, or a specific time of day. Drone Mode lets you scout the summit without making the entire climb first. If you spot a seasonal Photo Challenge asking for a landmark, read the wording carefully: “La Gran Caldera” and “Gran Telescopio” are not interchangeable location descriptions.
For PC players, this area showcases the difference between distant geometry settings. Lowering environment texture quality saves VRAM, but reducing world detail too aggressively makes the summit look noticeably flatter. A 60-fps cap with high textures and medium shadows generally looks better than uncapped performance that constantly swings between 55 and 90 fps.
Barn Finds are time-gated secrets, not random map loot
Barn Finds are among Forza Horizon 5's most famous hidden locations, but the game deliberately obscures how they work. Barns don't all appear immediately. Some are linked to specific Horizon Adventure chapters, player progression, or rumor prompts from characters such as Alex and Rami. Once a rumor is active, a purple search circle appears; the abandoned car is somewhere inside that area, not necessarily at its center.
Don't spend 20 minutes combing every pixel by car. Open Drone Mode, climb above tree level, and search for a rectangular roof, weathered walls, and a clearing that breaks the surrounding vegetation. Mexico's jungle and farmland can swallow a barn visually, especially during rain. Flying the drone in a slow grid pattern is far faster than driving randomly.
When you discover a Barn Find, the restoration process takes real time. Credits can accelerate restoration, but saving money is usually smarter early in the campaign because Barn Find cars are collection rewards rather than instant competitive upgrades. The 1963 Volkswagen Beetle, 1968 Renault 4L Export, and 1970 GMC Jimmy each have their own personality, but none should force you to delay essential car purchases or festival expansion.
| Secret type | How it unlocks | What to look for | Best hunting tool |
|---|---|---|---|
| Barn Find rumor | Progression or character prompt | Purple search zone | Drone Mode |
| XP board | Available from the start in most cases | Blue board on walls, roofs, or ramps | Fast Travel and rewind |
| Landmark or photo spot | Usually always available | Named structure or distinctive scenery | Photo Mode location search |
The important distinction is simple: a Barn Find rumor gives you a search area, while an XP board can often be discovered whenever you can physically reach it. If you see a barn icon but no active rumor, continue Horizon Adventure rather than assuming the game is bugged.
Chase the Halo Warthog and its hidden showcase flavor
One of Forza Horizon 5's best Easter eggs is the Halo crossover built around The Spartan Showcase Event. This isn't merely a car delivery with a Halo badge attached. The event recreates the feel of a chaotic Halo chase, complete with Master Chief-themed dialogue, recognizable military imagery, and off-road action that makes the Warthog feel like a vehicle from another game.
To reach it, progress through the Horizon Adventure campaign until Showcase Events and the relevant Horizon Baja content become available. If The Spartan is not on your map, you haven't necessarily missed it; campaign chapter unlocks control when several activities appear. Complete the preceding Baja objectives and check the Showcase filter rather than searching every road in Mexico.
The Warthog is entertaining but not a top-tier road racer. Its high ride height and off-road character make it excellent for dirt trails, jumps, and cross-country events, while its weight and limited road precision make it a poor choice for technical asphalt circuits. Use it for the experience and the collection, then switch to a dedicated rally build when leaderboard pace matters.
There are several other Halo-flavored details around the event, so don't skip the opening dialogue or immediately restart after crossing the finish line. Horizon 5 loves hiding its jokes in presentation, not just in collectible objects. The official Forza Support site is worth checking if a showcase fails to trigger after the required campaign step.
Find Night City in the Quadra V-Tech crossover
The Cyberpunk 2077 crossover is another secret worth replaying because it turns a normal Horizon activity into a deliberate Night City tribute. The star is the Quadra V-Tech, a rear-wheel-drive muscle car with an aggressive stance, futuristic bodywork, and a soundtrack-friendly presence that feels completely different from Mexico's rally and supercar crowd.
Look for the Cyberpunk-themed Street Scene showcase or its associated Horizon Adventure activity after unlocking Street Scene progression. The activity is generally marked on the map once available, but many players miss it because they treat every icon as a standard race. Read the event title and listen to the dialogue; the crossover references are part of the reward.
The Quadra is most enjoyable with a balanced street tune rather than maximum power. Keep the rear tires controllable, use a modest differential setting, and avoid an overpowered engine swap until you've learned its throttle behavior. A stock or lightly upgraded Quadra can rotate beautifully through medium-speed corners, but too much power turns exits into smoky three-second corrections.
For collectors, this is one of the strongest Easter-egg cars because it has a distinct identity rather than being a generic reward with themed paint. It also makes a great subject for a neon-heavy Guanajuato photo session. For more crossover-style hunting, the Everspace 2 hidden-rewards guide has the same useful mindset: inspect unusual spaces instead of only following quest markers.
Use the map and PC settings to hunt efficiently
Secret hunting becomes much faster when your interface and performance settings stop fighting you. First, buy Casa Bella near Mulegé when you can afford it. Its perk grants a free Skill Song, and owning additional houses unlocks useful travel options and convenience. The Buenas Vistas house on the west coast is even more valuable for exploration because it unlocks Fast Travel to any road after purchase, although it costs 2,000,000 credits.
Fast Travel still charges credits unless you smash all 50 Fast Travel boards. That makes board hunting a genuine long-term investment, not busywork. Use the map's filter controls to hide races and showcase icons temporarily. Then work by region: clear Guanajuato, the volcano, jungle roads, and the western coast instead of teleporting randomly across the whole map.
| PC setting | Recommended value | Performance impact | Visual note for exploration |
|---|---|---|---|
| Environment Texture Quality | High if VRAM allows | Moderate VRAM use | Keeps distant rocks and buildings sharp |
| Shadow Quality | Medium or High | Moderate GPU impact | High improves tunnel and forest depth |
| Reflection Quality | Medium | Moderate to high | Lower values affect Guanajuato windows and wet roads |
| MSAA | 2x or 4x | High at 4x | Useful for power lines and thin scenery edges |
| Motion Blur | Off for searching | Negligible | Makes drone scouting and board spotting clearer |
| Frame Rate | Stable 60 or 120 fps cap | Depends on hardware | Consistency helps precision driving more than peaks |
For official patch notes and current event rotations, follow the Forza.net news page. Seasonal content can temporarily spotlight locations, but the permanent secrets remain available through campaign progression and free exploration. If you're tuning a portable PC or older desktop, our max-FPS settings guide offers a useful rule: cap the frame rate where your system is stable instead of chasing an inconsistent maximum.
The smartest order for a complete secret sweep
Start by unlocking enough Horizon Adventure chapters to activate Barn Find rumors, Showcase Events, Street Scene content, and the major festival sites. Next, buy Buenas Vistas if your credit balance can survive it; Fast Travel dramatically reduces dead time. After that, clear XP and Fast Travel boards around Guanajuato, then work outward through the volcano, jungle, and coast.
Keep three cars ready: a nimble AWD rally car for dirt and volcano climbs, a compact road car for Guanajuato, and a high-clearance off-roader for board jumps and jungle paths. Use Drone Mode before every search circle, and don't ignore overhead spaces. Horizon 5 hides rewards on rooftops, behind walls, at the end of tunnel branches, and on slopes that look decorative until you approach them.
The final trick is to treat Horizon Mexico like a place rather than a menu of events. Stop at landmarks, read the names of roads, replay crossover showcases, and check suspicious dead ends. The game is at its best when the next discovery isn't marked with a giant objective icon. That's where the Gran Telescopio, the Halo Warthog, the Quadra V-Tech, and the last stubborn Fast Travel board become more than checklist items—they become stories you found yourself.
