Top Walking Trails in Paris, Ranked by Distance and Difficulty

Parisians itching to take their fitness outdoors this July are spoiled for choice when it comes to city walking trails, with routes ranging from relaxed riverside ambles to robust woodland circuits. This summer, new wayfinding signs posted by the Mairie de Paris highlight four of the city’s most-used paths, all rated for distance, surface and intensity.

With school holidays upon us and summer temperatures hovering near 28°C according to Météo-France, staying active can mean escaping stuffy gyms for the capital’s plentiful parks and riverbanks. The recent launch of the Paris Marche app—listing over sixty mapped trails with gradings for stairs, inclines and distances—makes it easier for residents to pick a safe and suitably challenging walk, even in urban heat.

Four Must-Try Routes for Every Walker

For a flat, accessible stroll, the Seine Riverbanks route is a perennial favorite: pick up the promenade at Pont d’Arcole and follow the pedestrian Quai de la Tournelle for a 4.5 km (one-way) riverside walk, passing Île Saint-Louis and finishing near the Jardin des Plantes. This section, officially part of the Berges de Seine, is entirely car-free and paved, making it suitable for pushchairs and those looking for an easy, social outing. The mild gradient makes this a low-difficulty option—perfect for families or those easing back into exercise.

For those seeking a little more challenge and shade, the Bois de Boulogne in the 16th arrondissement is home to the city’s longest marked circuit: the "Boucle du Grand Lac." Spanning 11 km around Lac Inférieur, this dirt-and-gravel path includes gentle hills (total elevation gain roughly 120 metres) and forested stretches. Paris Rando, an association promoting group hikes, rates this loop as moderately difficult: plan 2.5 to 3 hours for the full round, with public toilets and a handful of cafés at the northern edge near Avenue de Longchamp. Cyclists and runners share parts of the route; signage installed in May now clearly distinguishes the walking lanes.

Numbers Show a Summer Walking Boom

The appetite for outdoor walking is evident. According to the latest figures from Paris’s Direction des Espaces Verts et de l’Environnement, footfall counters along the Seine and in the Bois de Vincennes registered a 19% jump in visitors this June compared to last year, approaching 350,000 total walking entries per month at peak spots. Both parks remain free to enter and open from 7am to 10pm daily in July and August. The new Paris Marche app (available since 20 June) reports nearly 15,000 downloads, with users spending an average of 25 minutes per session choosing trails or tracking walks.

Other notable routes include the Promenade Plantée, the city’s original elevated greenway in the 12th, with a 4.7 km walk from Bastille to Porte Dorée and gentle slopes, and the shady, slightly more demanding perimeter trail at Parc des Buttes-Chaumont in the 19th, clocking in at 2.6 km with some brisk ascents.

Entry to all these parks is free. Guided group walks organised by Paris Rando start at €8 for non-members and take place every Saturday morning—registration opens weekly at www.parisrando.org.

Choosing the Right Walk for You

Locals are encouraged to consult the Paris Marche app or the new citywide wayfinding signs before heading out, with trail difficulty and distances clearly listed in French and English. Early mornings (before 9am) or late evenings (after 7.30pm) are recommended for cooler temperatures and lighter crowds, especially on weekends. Water fountains are dotted along major trails, but city officials advise walkers to carry their own refillable bottles during heatwaves. For those with mobility concerns, flat riverbank promenades like the one between Pont Neuf and Pont d’Austerlitz remain the most accessible.

With the holiday season in full swing and foot traffic still on the rise, walkable Paris is more welcoming—and better signposted—than ever. Check local park websites for temporary construction updates, and consult a local medical professional for personal health advice before dramatically upping your physical activity.
