Clair Obscur: Expedition 33, developed by Sandfall Interactive, has taken the RPG world by storm with its hauntingly beautiful Belle Époque-inspired fantasy setting, gripping narrative, and innovative hybrid combat system. Released on April 24, 2025, for PC, PS5, and Xbox Series X|S, this turn-based masterpiece invites players to guide Gustave and his expedition team across The Continent to confront the Paintress, a godlike entity who dooms people of a specific age to vanish each year. While the main quest is a thrilling journey, the game’s optional side areas are where its world truly shines. These zones, packed with loot, lore, and challenges, offer unforgettable experiences for players willing to stray from the golden path. Here are the top 10 side areas you should definitely explore in Clair Obscur: Expedition 33, and why they’re generating so much buzz among players.

1. Yellow Harvest

Located in Act 1, Yellow Harvest is a golden-hued paradise that contrasts with the game’s darker themes. Its swaying fields and paint-corrupted patches create a surreal atmosphere, perfect for early-game exploration. Players can tackle Paint Cages—chests requiring you to shoot three glowing locks hidden in the environment—to earn Resplendent Chroma Catalysts for weapon upgrades. The optional boss, Harvest Warden, tests your combat skills with fire and ice attacks, rewarding a Weakness Gain Pictos that boosts damage against enemy weak points. Scattered Expedition Journals hint at past failures, adding depth to the Paintress’s curse, while chasing Petanks for Healing Tint Shards is a fun diversion. Yellow Harvest’s accessibility and rewards make it a must-visit for leveling up early.

2. Frozen Hearts

Accessible in Act 2, Frozen Hearts is a chilling, ice-covered zone that challenges players with slippery terrain and elemental enemies. The area’s blue-tinted caverns and frozen lakes are visually stunning, reflecting the game’s clair-obscure aesthetic of light and dark contrasts. Here, you’ll encounter Chromatic Nevrons, enemies that shift elemental weaknesses, requiring quick adaptation. Solving ice-based puzzles, like sliding blocks to unlock paths, leads to a hidden Music Record for your camp playlist. Helping a white-painted Nevron by finding a Frost Shard rewards a powerful Pictos, while the optional boss, Glacial Sovereign, drops a Frostbite Pictos for crowd control. Frozen Hearts’ blend of beauty and danger is irresistible.

3. Hidden Gestral Arena

The Hidden Gestral Arena, available late in Act 2, is a combat enthusiast’s dream. This sandy coliseum, tucked away near Gestral Beach, pits you against four Gestral Champions—wooden mannequin-like merchants who love a fight. Each victory grants a unique Pictos that boosts solo combat prowess, ideal for players who enjoy tweaking builds. The arena’s vibrant crowd and theatrical battles add a lighthearted vibe, contrasting the game’s somber tone. Navigating to the arena requires Esquie’s coral-breaking ability, so ensure you’ve collected his missing rocks. The arena’s high-level challenges and rewarding loot make it a standout for endgame preparation.

4. The Red Woods

The Red Woods, accessible in Act 3, is a haunting forest bathed in crimson light, where paint corruption runs rampant. This zone is home to a friendly Nevron who trades Chroma for a powerful Pictos, though beware—he becomes a formidable optional boss if you choose to fight him later. The area’s twisting paths and glowing flora hide Expedition Journals that reveal tragic stories of past expeditions, enriching the game’s lore. Jumping puzzles lead to a Colour of Lumina, boosting your Pictos effects. The Red Woods’ eerie beauty and high-stakes encounters make it a memorable detour for lore hunters and combat lovers alike.

5. Rsoteric Ruins

Found in Act 2, Rsoteric Ruins is a crumbling temple overrun with paint spikes and Nevrons. Accessing a small island nearby requires Esquie’s coral-destroying ability, where defeating three enemies drops a Level 10 Cruleram, Chation, and a Resplendent Chroma Catalyst. The ruins’ intricate architecture and hidden Paint Cages reward thorough exploration with rare materials. An optional boss, the Ruins Keeper, guards a Pictos that enhances AP generation, crucial for tough fights. The zone’s ancient, mysterious vibe and high-value loot make it a favorite for players seeking to power up their party.

6. Flying Waters

Flying Waters, encountered in Act 1, is a surreal zone where water flows upward, defying gravity. Its ethereal beauty, with floating platforms and shimmering cascades, is a visual highlight. Players navigate grapple points and platforming challenges to reach hidden collectibles, like a Music Record or an Outfit for Maelle. The zone’s boss, Goblu, is a great opportunity to earn the “Professional” achievement by defeating it without taking damage, thanks to its predictable attacks. Side quests, like helping a Nevron with a nearby item, yield Healing Tints, making Flying Waters a rewarding early detour.

7. Clea (Flying Manor)

Clea, the Flying Manor, is a late-game optional area recommended for level 80 players, despite some guides suggesting 95+. This airborne mansion, accessible in Act 3, is a labyrinth of gilded halls and paint-corrupted rooms. Its puzzles, like aligning mirrors to redirect light, unlock rare weapons like the Sireso for Verso, which boosts team-wide damage. The manor’s optional boss, a spectral guardian, drops a Pictos that revives fallen allies, a game-changer for tough battles. Clea’s opulent design and high-level challenges make it a thrilling endgame destination.

8. Simon (Renoir’s Drafts)

Simon, or Renoir’s Drafts, is an Act 3 zone resembling an artist’s chaotic sketchbook, with shifting landscapes and paint streaks. Recommended after Clea, this area features platforming challenges and Paint Cages hiding Chroma Elixirs. The optional boss, a living canvas, requires precise dodging of ink-based attacks, rewarding a Pictos that enhances elemental damage. Expedition Journals here hint at the Paintress’s origins, adding narrative weight. Simon’s surreal, ever-changing environment and rich rewards make it a must for players chasing story and power-ups.

9. Ancient Sanctuary

The Ancient Sanctuary, accessible in Act 2, is a sacred ruin with glowing glyphs and paint spikes. A hidden Paint Spike here holds a rare collectible, and solving glyph-based puzzles unlocks a Colour of Lumina. The zone’s enemies, weak to fire, are perfect for testing Lune’s elemental skills. An optional boss, the Sanctum Watcher, drops a Pictos that boosts parry rewards, ideal for defensive builds. The Sanctuary’s serene yet ominous atmosphere and valuable loot make it a compelling side trip.

10. Gestral Beach

Gestral Beach, available across multiple zones, is a quirky coastal area where Gestral merchants challenge you to duels to unlock their shops. Winning these fights grants access to rare Tints and Music Records, while the beach’s relaxed vibe—complete with dancing Gestrals in swimsuits—offers a humorous break. Hidden collectibles, like Expedition Journals, are tucked behind coral barriers, requiring Esquie’s abilities. The beach’s lighthearted challenges and unique rewards make it a delightful detour for completionists.

Why These Areas Matter

These 10 side areas showcase Clair Obscur: Expedition 33’s brilliance in blending exploration, combat, and storytelling. Each zone is visually distinct, from the golden fields of Yellow Harvest to the surreal cascades of Flying Waters, reflecting the game’s clair-obscure aesthetic. They offer practical rewards—Pictos, weapons, and materials—that enhance your party’s combat prowess, crucial for tackling the Paintress and her Nevrons. The hybrid turn-based and real-time combat system shines in optional boss fights, where dodging, parrying, and exploiting weaknesses are key. For example, equipping lightning-infused weapons in Yellow Harvest or fire-based skills in Ancient Sanctuary can turn tough battles into manageable victories.

Beyond loot, these areas deepen the game’s narrative. Expedition Journals scattered throughout reveal the tragic fates of past expeditions, while interactions with friendly Nevrons, like helping one in Frozen Hearts, add emotional weight. The zones also encourage creative exploration, with no minimap forcing players to rely on visual cues like lanterns or paint streaks. Esquie’s traversal abilities, unlocked by finding his missing rocks, open new paths, rewarding persistence with hidden alcoves and collectibles. These mechanics make every side area feel integral to the expedition’s journey, not just filler.

For players, these areas extend the game’s 30-hour main campaign by another 20-30 hours, offering challenges for all skill levels. Whether you’re a completionist hunting achievements, a lore enthusiast unraveling the Paintress’s mystery, or a combat lover testing builds in the Hidden Gestral Arena, there’s something for everyone. The absence of a quest log means you’ll need to track side objectives manually, but the rewards—stylish Outfits, powerful Pictos, and heartfelt character moments—are worth the effort.

Tips for Exploration

To maximize your experience, rest at Expedition Flags to heal and allocate skill points, but beware—resting respawns enemies, so use Chroma Elixirs for quick heals. Pay attention to enemy weaknesses, listed in the Battle Wheel, and experiment with Pictos to boost AP or damage. When navigating, look for Esquie’s rocks to unlock abilities like swimming or breaking Paint Spikes, which grant access to hidden areas. Finally, don’t skip friendly Nevrons—their quests often yield rare items and add charm to the world.

They’re vibrant, rewarding extensions of a world brimming with beauty, danger, and mystery.
