Marly Park and Louveciennes Forest Loop

This moderate jogging loop, spanning 8.66 km, usually takes around 1 hour to complete. Your actual time may vary depending on your pace and how often you stop to enjoy the scenery.

The loop features a varied and engaging terrain. While it primarily consists of paved surfaces, you'll also encounter rolling sections with enough elevation gain to provide a good workout. The broader Forêt de Marly includes some unpaved, mellow trails that can be muddy, so be prepared for mixed conditions.

Rated as 'moderate', this loop requires a reasonable level of physical fitness due to its rolling terrain and elevation changes. While not overly strenuous, it's best suited for joggers who are comfortable with a bit of a challenge rather than absolute beginners.

You'll experience a blend of natural beauty and historical significance. Keep an eye out for the Marly watering trough and the Tapis Vert of Parc de Marly. The forest itself, once a royal hunting ground for Louis XIV, is dotted with over fifty ponds and offers a wilderness atmosphere with potential sightings of roe deer and squirrels.

Autumn is particularly beautiful for jogging this loop, as the deciduous trees (like oak and chestnut) transform into vibrant landscapes. However, the trail offers a refreshing escape year-round, with each season bringing its own charm.

The area is easily accessible from Paris. You can reach the heart of the Forêt de Marly directly via public transport, with the Saint-Nom-La-Bretèche Forêt de Marly train station serving as a convenient access point. Specific parking details for the trailhead are not provided, but public transport is a strong option.

Generally, dogs are permitted in the Forêt de Marly, but it's always best to keep them on a leash to protect wildlife and ensure a pleasant experience for all visitors. Please check local signage for any specific restrictions within the Parc de Marly itself.
