1. Secret Covered Passages of Central Paris
Paris’s network of 19th‑century passages, glass‑roofed arcades like Galerie Vivienne and Passage des Panoramas, are a treasure trove of hidden gems. Just a stone’s throw from Rue de Rivoli, you’ll stroll past boutique bookstores, vintage toy shops, and patisseries that feel lifted from a storybook. These covered ways were built to bypass the muddy streets of medieval Paris and today offer a beautiful fusion of old-world charm and modern style.
Insider tip: Visit on a rainy afternoon, sip hot chocolate at Café Vivienne, and marvel at the mosaic floors. Keep your eyes peeled for a secret apartment tucked behind ornate doors, one of many secret spots that only locals know about.
2. A Serene Oasis on La Promenade Plantée
Also called the Coulée Verte René-Dumont, la Promenade Plantée is a lush, elevated park built atop an old railway viaduct (the original railway line from the 19th century). Stretching through the Latin Quarter and Bastille, it offers a welcome break from the bustling streets below. Wander along winding paths lined with rose gardens and modern art installations, and you’ll feel a world away from the Seine.
Why it’s unique: Unlike most urban parks, this greenway preserves snippets of world war history and Victorian engineering. At one end, it leads almost directly to the Parc des Buttes Chaumont, another tranquil oasis known for its cliffside views and suspension bridge.
3. Underground Mysteries: The Paris Catacombs & Beyond
Beneath the city’s narrow cobblestone streets lies a secret world: the Paris Catacombs. While most tourists know the public route, few venture deeper on a guided walking tour that reaches the final resting place of millions. Bring a flashlight to explore off‑limits chambers lined with skulls and femurs, learning about centuries of rich history, epidemics, and urban reforms.
Firsty‑enabled tip: Download your digital map underground, where Wi‑Fi dies, your eSIM connection stays strong, so you can easily follow your guide’s route and capture beautiful photos in eerie low light.
4. From Sewers to Secrets: The Paris Sewer Museum
Just a stone’s throw from Notre Dame, the Paris Sewer Museum (Musée des Égouts) invites history buffs to navigate the labyrinthine tunnels that handle the city’s wastewater. Don a hard hat and follow raised walkways past plaques explaining how engineers overhauled sewers in the 19th century. You’ll be surprised at how this unconventional visit becomes a must‑see.
Why it stands out: It’s a true hidden gem, far removed from tourist traps, offering insights into Paris’s public health revolution and its vast collection of underground infrastructure.
5. Sunset Cruise & Floating Cinema on the Seine River
Imagine boarding a vintage barge on the Seine River at dusk, the water reflecting the golden glow of the Eiffel Tower as you take your seat for a French classic on a big screen. This floating cinema pairs film screenings with gourmet snacks and hot chocolate for cooler evenings. It’s a romantic, immersive twist on a typical day trip cruise.
Insider tip: Book the “Mona Lisa” screening around sunset, there’s something magical about watching the film as Paris’s landmarks glide past your window.
6. Belleville’s Street Art Scavenger Hunt
Paris lies in layers of creative expression, and nowhere is that more apparent than Belleville’s street art. This interactive street art tour uses QR codes and augmented‑reality murals to guide you through graffiti alleys, pop‑up galleries, and works by famous artists like JR. It’s a living museum where every wall tells a story.
Why it’s special: You’ll uncover many hidden gems, stenciled portraits, political collages, and even a tribute to Jim Morrison near the old Cirque d’Hiver. Perfect for art lovers seeking insider access.
7. Île de la Cité & Square du Vert-Galant
The historic heart of Paris, Île de la Cité, is home to Notre Dame and the Place des Vosges, but also to lesser‑known treasures. Tucked at the island’s western tip is Square du Vert Galant, a peaceful spot shaded by plane trees, where you can picnic on sandstone benches overlooking river confluences.
Hidden detail: Walk past the official barricades to find a tiny staircase leading to a secluded riverside gazebo, a favourite hidden gem for locals.
8. Medieval Marvels: Musée de Montmartre & Napoleon’s Vineyard
Up in Montmartre, the Musée de Montmartre showcases works by Toulouse-Lautrec and Renoir, set inside the oldest house on the hill. Behind the museum, you’ll discover the last terrace of Montmartre’s original vineyard, once tended by Marie Antoinette’s gardener.
Why it’s unforgettable: You can stroll past flowering vines, pause at a quiet corner to sip rosé or even take a cooking class in the museum’s garden kitchen, learning authentic French pastry techniques.
9. Gothic Grandeur & Ghosts at Notre Dame Cathedral
Though it’s recovering from the fire, Notre Dame Cathedral remains a Gothic icon. Skip the daytime crowds and book an evening lantern tour of the façade and crypt. Your guide—often a medievalist—will recount tales of middle ages rituals, the cathedral’s use as a revolutionary headquarters, and rumored hauntings by clerics of old.
Plus: Just beneath, you can explore the archaeological crypt’s rich history exhibits, revealing Gallo‑Roman foundations and remnants of the famous artists who sculpted its gargoyles.
10. Le Marais & the Musée des Arts Forains
Le Marais pulses with bustling city energy, bohemian vibes in Saint Germain’s sister quarter. But off the beaten path, you’ll find the Musée des Arts Forains, a private carnival museum housed in a Belle Époque ballroom. Climb aboard antique carousels, join a fairground shooting gallery, and try 19th‑century carnival games.
Don’t miss: The medieval banquet hall replica, where you can book a private after‑hours evening with theatrical performances and unlimited mulled wine.
11. Canal Saint-Martin & Secret Apartments
Follow the towpaths of Canal Saint Martin, where iron footbridges arch over mirror‑flat water. Along the way, discreet plaques mark former entrances to hidden apartments—once squats occupied by impressionist painters. Today, intimate dinners are occasionally hosted in these converted lofts, offering multi‑course menus from local chefs.
Local tip: Arrive just before the previous night’s lock closures and watch barge operators in action—then grab a crepe from a canal‑side vendor.
12. Rooftop Beekeeping in the Heart of Paris
Few think of Paris as a city of hives, but atop municipal buildings in the Latin Quarter and Rue de Rivoli, urban beekeepers tend their colonies. Join a rooftop workshop to don beekeeper’s gear, inspect frames, and taste fresh honey. By the end, you’ll understand how these rooftop hives contribute to biodiversity in the french capital.
Why it’s unique: You’ll leave with a jar of honey stamped with the date, proof of your hands‑on experience high above the bustling streets.
13. Montparnasse’s Hidden Rooftop Yoga at Sunrise
Before the city awakens, head to Montparnasse Tower’s rooftop terrace for a sunrise yoga class that overlooks the Arc de Triomphe, the Eiffel Tower, and the Sacré-Cœur. The gentle flow sequence, led by a local instructor, ends with a meditative tea ceremony in a glass pavilion.
Firsty‑enabled tip: Stream a live playlist from your Firsty eSIM to set the perfect soundtrack—no buffering, even at dawn.
14. The Forgotten Railway: La Petite Ceinture
Once Paris’s circumferential train route, la Petite Ceinture was abandoned in the 1930s and reclaimed by nature. Now, sections in the 15th and 16th arrondissements host guided urban hikes through overgrown tunnels, wildflower‑lined tracks, and graffiti‑tagged viaducts. It’s an absolutely beautiful juxtaposition of decay and rebirth.
Photographer’s note: Dawn light filters through broken panes, casting moody shadows, ideal for beautiful photos.
15. Marais Ghost Tour & Secret World War Trails
After dark, join a World War II historian for a walking tour of Le Marais’s hidden Resistance sites. Under the dim glow of streetlamps, you’ll pass the former Nazi headquarters, clandestine print shops, and a secret apartment that sheltered Jews.
Why it sticks with you: The guide’s vivid storytelling brings the middle ages and modern conflicts into a tangible present, reminding you how Paris’s layers of history still resonate.
16. Picnic in the Rose Gardens of Place des Vosges
One of Paris’s oldest squares, the Place des Vosges, is ringed by red‑brick arcades and lush rose gardens. Spread a blanket on the manicured lawn, unpack a baguette and cheese from a nearby fromagerie, and watch Parisians stroll by in slow‑motion elegance.
Local secret: On certain weekends, you may catch a harp recital under the vaulted ceilings of La Carreau du Temple, another favourite hidden gem just around the corner.
17. Day Trip to Château de Versailles Hidden Trails
No list of unique things to do in Paris is complete without Versailles, but skip the palace crowds. Instead, book a bike tour through the Grand and Petit Trianons’ back trails, exploring Marie Antoinette’s rustic hamlet and private groves. Your guide will share tales of court intrigue and lost passageways that allowed royals to move unseen.
Pro tip: Bring your Firsty‑enabled GPS to navigate unmarked forest paths, no paper maps needed.
18. Culinary Capers: Private Cooking Class in Saint-Germain
If you dream of mastering coq au vin or flaky croissants, a private cooking class in Saint Germain is the way to go. Hosted in a historic townhouse overlooking the Seine, you’ll shop for fresh produce with a local chef, then learn technique and folklore behind each dish.
Why it’s memorable: You dine with fellow students around a communal table, savoring your creations alongside seasonal French wine, a perfect blend of hands‑on learning and conviviality.
19. The Grand Mosque & Its Tranquil Oasis
Tucked behind the Panthéon, the Grand Mosque of Paris is an unexpected haven of Moorish design: horseshoe arches, intricate tile work, and a courtyard surrounded by orange trees. After touring the prayer hall, slip into the hammam for a traditional steam bath, an unforgettable adventure away from tourist traps.
Firsty‑enabled tip: Book your spa slot online via Firsty to avoid the on‑site queue, then stream meditation tracks as you relax.
20. Sunset at the Arc de Triomphe: Stadium‑Style Stairs
Everyone knows the Arc de Triomphe, but few climb its narrow spiral at sunset. After ascending 284 steps, you’ll emerge onto the rooftop terrace to see Paris bathed in golden light. From here, the Champs‑Élysées is just a stone’s throw away, and the city’s 12 grands boulevards stretch to the horizon.
Why it’s special: Late‑summer humidity means fewer crowds, and the skyline view—with the Eiffel Tower framing the silhouette of Montparnasse Tower, makes for beautiful Paris memories.
