1. La Cité (Medieval Citadel)

The spectacular walled fortress with 52 towers that inspired Disney castles worldwide and remains one of Europe’s largest intact medieval cities.
Insider Tip: Enter through Porte Narbonnaise early (before 9am) to experience the winding streets without crowds, and walk the entire wall circuit counterclockwise for the most dramatic reveals of the countryside.

2. Basilica of Saint-Nazaire

This stunning church combines Romanesque and Gothic architectural styles with some of the finest medieval stained glass in southern France.
Insider Tip: Look for the small door on the north side that leads to a hidden staircase where you can climb to see the stained glass windows up close – most visitors miss this opportunity.

3. Château Comtal (Count’s Castle)

The impressive inner fortress within the citadel offers a fascinating glimpse into medieval military architecture.
Insider Tip: The included audio guide skips many interesting details; instead, time your visit for the 2pm English tour when guide François often shares captivating stories about siege warfare techniques.

4. Bastide Saint-Louis (Lower Town)

The charming grid-pattern “new town” (still dating from the 13th century) with its attractive central square and local atmosphere.
Insider Tip: Visit the covered market on Saturday mornings when local farmers bring specialties, then enjoy your purchases in the peaceful gardens behind Saint-Michel Cathedral.

5. Pont Vieux (Old Bridge)

The picturesque medieval bridge spanning the Aude River offers classic views of the fortress.
Insider Tip: Walk halfway across at sunset, then look back toward the citadel for a spectacular photo opportunity that professional photographers favor when the fortress walls glow golden.

6. Canal du Midi

This UNESCO-listed waterway connects the Mediterranean to the Atlantic and offers beautiful towpath walks.
Insider Tip: Skip the touristy boat rides and instead rent bicycles from “Le Vélo Vert” to cycle the shaded towpath to the charming Trebes locks, stopping for wine tasting at Château Pennautier.

7. Museum of Fine Arts (Musée des Beaux-Arts)

Housed in the former Présidial building, this museum showcases impressive Flemish, Dutch, and French paintings.
Insider Tip: The third-floor collection of local landscapes reveals viewpoints that still exist – ask at the desk for their hand-drawn map showing where you can find these exact views today.

8. The Ramparts (Les Remparts)

The massive double walls that encircle La Cité stretch nearly 3km and offer spectacular walking and viewing opportunities.
Insider Tip: Access the lesser-visited western section through Tour du Grand Burlas for crowd-free exploration and the best sunset positions overlooking the Aude valley.

9. Lac de la Cavayère

This pleasant lake just outside town offers beaches, water activities, and hiking trails through the surrounding forests.
Insider Tip: Skip the main beach and follow the trail clockwise around the lake for about 15 minutes to find a small hidden cove that locals call “Plage des Pins” where the water is clearer and crowds are rare.

10. Château de Pennautier

Often called the “Versailles of Languedoc,” this magnificent 17th-century château surrounded by vineyards offers tours and wine tasting.
Insider Tip: Book the “Secret Cellars” tour in advance (not advertised on their main website) to access underground passages connecting to the original wine cellars and taste reserve wines not available to regular visitors.
