Île-de-France is one of the most destination-dense regions on Earth. Within its 12,012 km² you will find the Louvre — the world's largest museum — the Palace of Versailles — the most opulent royal residence in Europe — the medieval spires of Chartres Cathedral, the Renaissance grandeur of Fontainebleau, the water-lily ponds of Monet's Giverny, and the fairy-tale castle of Disneyland Paris. And that is just the headline acts.
This guide covers the very best things to do in Île-de-France in 2026, with eco-friendly travel tips woven throughout so you can enjoy this extraordinary region while minimising your environmental impact. Every attraction is reachable by public transport from central Paris, and every hotel booking made through IMPT removes 1 tonne of CO₂ from the atmosphere.
No trip to Île-de-France is complete without a visit to the Château de Versailles, the UNESCO World Heritage palace of Louis XIV. The Hall of Mirrors, the King's Grand Apartments, and the 800-hectare gardens are among the most spectacular sights in Europe. The estate also includes the Grand Trianon, the Petit Trianon and the charming Queen's Hamlet — Marie Antoinette's rustic retreat.
Eco tip: Take the RER C train from central Paris to Versailles-Rive-Gauche — 35 minutes, €4 round trip, and produces just 0.5 kg CO₂ per passenger. Avoid taxis and private cars. Book your entry ticket online in advance to skip the queue and reduce paper waste.
Opening hours: Tue–Sun, 9am–5:30pm (gardens until 8:30pm summer). Allow at least half a day.
One of the largest royal palaces in France, the Château de Fontainebleau was home to monarchs from Louis VII to Napoleon III. Its 1,500 rooms span eight centuries of French architecture. The surrounding Forest of Fontainebleau — 25,000 hectares of ancient woodland, sandstone boulders and heathland — is a paradise for hikers, climbers and nature lovers.
Eco tip: Take the Transilien train from Gare de Lyon to Fontainebleau-Avon (45 minutes). The forest is free to enter and offers over 300 km of marked trails. Stay at a Green Key-certified hotel like Hôtel de l'Aigle Noir or the EU Ecolabel-rated Les Demeures de Fontainebleau.
Claude Monet's home and gardens in the village of Giverny (Eure, just west of Île-de-France's border) are a pilgrimage site for art and nature lovers. The famous water-lily pond, Japanese bridge and riotously colourful flower beds inspired some of the most iconic paintings of the Impressionist movement.
Eco tip: Visit on a weekday in May or June when the gardens are at their peak but the crowds are thinner. Take the train from Paris Saint-Lazare to Vernon-Giverny (45 minutes), then walk or cycle the 5 km to the gardens (free bike rental available at the station).
The Cathedral of Our Lady of Chartres is a masterpiece of French Gothic architecture. Its twin spires, luminous 13th-century stained-glass windows and labyrinth are UNESCO World Heritage-listed. The cathedral survived both world wars intact and remains one of the best-preserved medieval cathedrals in Europe.
Eco tip: Chartres is 1 hour from Paris Montparnasse by TER train (€15). The cathedral is free to enter. Combine your visit with a stroll through the medieval town centre and a picnic at the banks of the Eure river.
Disneyland Paris in Marne-la-Vallée (Seine-et-Marne) is the most visited theme park in Europe. The resort includes two parks — Disneyland Park and Walt Disney Studios Park — plus the Disney Village entertainment district. In 2026, new attractions and seasonal festivals make it a year-round destination for families.
Eco tip: The RER A train runs directly from central Paris to Marne-la-Vallée/Chessy station in 40 minutes. Disneyland Paris has committed to reducing its carbon footprint, with solar carports, waste-reduction programmes and eco-designed hotels. Book an eco-certified hotel outside the park for a more sustainable option.
A boat cruise on the Seine River is one of the most magical ways to see Paris. Glide past the Eiffel Tower, Notre-Dame, the Louvre, Musée d'Orsay and the Grand Palais. Evening cruises with dinner and sparkling lights are especially memorable. Several operators now offer electric boats and zero-emission vessels.
Eco tip: Choose a company that uses electric or hybrid boats — such as Vedettes de Paris or Bateaux Parisiens (some vessels now run on electric power). Walking the 7-km riverbank from Notre-Dame to the Eiffel Tower is a zero-emission alternative that reveals hidden views.
The hill of Montmartre in the 18th arrondissement of Paris is a village within the city. Climb the 270 steps (or take the funicular) to the Basilica of Sacré-Cœur for panoramic views over Paris. Wander the cobbled streets past artists' studios, the Place du Tertre and the vineyard of Clos Montmartre — the last working vineyard in Paris.
Eco tip: Visit early in the morning (before 9am) to avoid crowds and experience the basilica in silence. The walk from Anvers Métro station to the summit is steep but rewards you with a zero-emission sightseeing experience.
The Forêt de Fontainebleau is one of the most beautiful forests in France. Its dramatic sandstone boulder fields — known as the chaos — attract climbers from around the world, while the 300 km of walking trails offer everything from gentle family loops to full-day hikes. Keep an eye out for deer, wild boar and the rare heathland flora.
Eco tip: The forest is free. Take the Transilien train to Fontainebleau-Avon, then walk 15 minutes to the forest edge. The GR13 long-distance trail crosses the forest. Pack a picnic and carry out all waste.
While the Loire Valley is technically the next region south, the border is just an hour from Paris. Day trips from Île-de-France to Château de Chambord, Chenonceau and Cheverny are popular and easy. The Loire Valley is a UNESCO World Heritage site for its cultural landscape of châteaux, vineyards and historic towns.
Eco tip: Take the TGV from Paris Montparnasse to Tours (1 hour) and cycle between châteaux on the Loire à Vélo cycling route (600 km of marked paths). Electric bike rentals are widely available.
The Parc Naturel Régional de la Haute Vallée de Chevreuse is a protected area in Yvelines (78) and Essonne (91), just 30 km south-west of Paris. Rolling hills, medieval villages like Chevreuse and Dampierre-en-Yvelines, the ruined Château de la Madeleine, and the 17th-century Château de Breteuil make this a perfect green escape from the city.
Eco tip: Take the RER B to Saint-Rémy-lès-Chevreuse and walk into the park. The park visitor centre offers maps of eco-friendly trails. Combine with a visit to the organic farm at Ferme de Viltain for fresh produce.
Paris is home to some of the world's finest museums. The Louvre houses 38,000 works including the Mona Lisa and Venus de Milo. The Musée d'Orsay boasts the world's largest collection of Impressionist art. The Centre Pompidou is Europe's largest modern art museum. The Picasso Museum and Rodin Museum offer more intimate experiences.
Eco tip: Many museums now offer digital ticketing (no paper) and have sustainability policies. The Paris Museum Pass gives you access to over 60 museums and reduces the carbon footprint of repeated ticket purchases. Walk or use the Métro between museums — the Line 1 Métro connects the Louvre, Tuileries and Champs-Élysées.
The Gardens of Versailles are a masterpiece of French formal garden design. Rent a bike or an electric cart to explore the Grand Canal, the Neptune Fountain, the Orangery and the vast wooded areas. The gardens are free on days without the Musical Fountains Show.
Eco tip: Bike rental is available inside the gardens and produces zero emissions. Alternatively, walk the 5-km loop around the Grand Canal — a flat, pleasant route that takes about 1.5 hours.
