Arrive at Paris-Charles de Gaulle Airport around early evening (8–9 hour flight from Toronto). Skip the RER and take the *Roissybus* (€12.50) directly to Opéra; it's slower but gives you real Paris views and saves transport costs. Check into your hostel by 7 PM, drop your bag, and head immediately to Rue Mouffetard in the Latin Quarter (walkable from most central hostels, or a €2 Metro ride). This lively pedestrian street is packed with small produce vendors, crêpe stands, and locals—grab a savory crêpe from one of the corner vendors (€4–6) and a coffee from a neighborhood café. Wander the surrounding side streets until 10 PM to get your bearings and soak in the Friday evening energy without the tourist crowds that hit Champs-Élysées.

Start at Marché Bastille (Thursday–Sunday, Boulevard Richard-Lenoir, 7 AM–2 PM). This is where real Parisians shop—no tourist menus, just vendors selling produce, cheese, rotisserie chicken, and pastries. Grab a fresh croissant and strong coffee from a vendor stall (€3–5 total) and eat on a bench while observing locals. The market closes by 2 PM, so arrive by 8 AM to beat the crowds.

Walk east through the Marais district (20-minute walk or easy navigation). This neighborhood was historically bohemian and still retains that edge—narrow medieval streets, independent boutiques, and Jewish delis. Pop into L'As du Fallafel on Rue des Rosiers (€5–8 for a falafel sandwich; it's local, not touristy, despite modest fame). Spend 2 hours getting deliberately lost in the grid of alleyways—you'll stumble upon small galleries, vintage shops, and quiet courtyards. The 11°C mist will add atmosphere rather than hinder exploration.

Head to Canal Saint-Martin (15-minute walk north from Marais, or €2 Metro). This is where young Parisians congregate—atmospheric, never crowded with tour groups. Grab street food from vendors near the water: a croque-monsieur from a food truck (€6–7) or fresh sandwich from Du Pain et des Idées bakery nearby. Sit by the water until dusk (around 9:30 PM in late May), watching locals chat and cycle past. The mist will create moody, cinematic lighting.

Visit Marché d'Aligre in the 12th arrondissement (8 AM–1 PM, Thursday–Sunday). This is grittier and less polished than Bastille—filled with North African spices, vintage items, and serious food vendors. Grab a couscous or tajine from a vendor (€6–8) or fresh fruit and cheese for a picnic. The market is 25 minutes walk from central Paris; use the time to cut through residential neighborhoods. Brunch after: Café Charlot (actually, skip chain-like spots). Instead, find a tiny neighborhood café in the 12th and order an *omelette* and *orange pressée* (fresh-squeezed orange juice, €3–5). Ask locals for a recommendation—this becomes part of the adventure.

Catch your flight from CDG around 3–4 PM on Sunday (giving yourself until noon to pack). Walk to the nearest Metro station by 1 PM and take the Roissybus back (€12.50). You'll have spent zero money on taxis or tourist transport and eaten better than most travelers spending 5x your budget.
