Looking for a nature getaway just under an hour from Paris? The Atout Branches Park, located in Milly-la-Forêt in the Essonne département (91), nestled within the Gâtinais Français Regional Natural Park, promises a perfect day of outdoor adventures in the heart of the Fontainebleau Forest for the whole family. Established in 2003 and taken over in 2021 by two outdoor enthusiasts, this park welcomes adventurers from as young as 2 years old for an immersive natural experience just 50 kilometers from Paris. Come 2026, the park will unveil two new experiences: a mini-golf course in the woods and two exclusive Mystery Games, Le totem sacré (The Sacred Totem) and Le refuge (The Refuge).

What to Do at Atout Branches? A Program for Every Profile

Atout Branches isn’t just a spot for a quick activity—it’s a place for a full day of adventure. The heart of the park is, of course, its tree climbing course, featuring 11 progressively challenging trails ranging from ground-level options for the little ones as young as 2, to an 18-meter-high panoramic trail. Each age group has its tailored level: Pitchounes (2-4 years), Bambins (4-7 years), Children (8-9 years), Juniors (10-14 years), and Adults (15 and up). The courses are navigated in supervised self-guided sessions, allowing everyone to progress at their own pace. Expect to spend between 1.5 and 2 hours to enjoy several courses back-to-back.

The 10-meter outdoor climbing wall expands the sports options available. Open to those aged 8 and up, it features three difficulty levels (green, blue, or red routes) and is equipped with the automatic DYNO system for a safe descent. It's a great alternative for anyone eager to climb without venturing into the trees.

Escape rooms, laser tag, and puzzle courses: indoor adventures to explore too

Atout Branches stands out for its unique blend of physical challenge and mental strategy. The Connected Escape Game 2.0, equipped with geolocated tablets, offers three outdoor adventures that can be enjoyed year-round: The Last Dragon (for ages 8 and up, 1 hour 20 minutes), Alice’s Mystery and the Chronogear (ages 12 and up, 2 hours), and Jack Black’s Treasure (ages 14 and up, 2 hours). A fourth adventure, The Witch’s Return, is available exclusively during the All Saints’ Day holidays.

For children aged 6 to 12, the puzzle courses (such as Explorer Koala or Druid Reflection) offer around 45 minutes of forest exploration with a booklet in hand. And for the younger crowd aged 5 to 10, the classic pirate treasure hunt remains a favorite at the park. For those seeking collective adrenaline, the Outdoor Laser Tag (available from age 7, for teams of 8 to 14 players) guarantees two thrilling 10-minute sessions in the open air, promising unforgettable team confrontations.

The Two New 2026 Mystery Games: The Sacred Totem and The Refuge

Big news on the adventure front for 2026. The park is unveiling two brand-new Mystery Games, an innovative concept that combines traditional Escape Games with outdoor puzzle trails. Entirely played on the ground amidst the trees, these adventures are open to anyone aged 12 and over.

The Sacred Totem transports players deep into a forgotten jungle, as they search for an ancient relic of power hidden by a long-lost tribe. Your task is to decipher clues to uncover your role in this mysterious quest... and perhaps become the new custodians of the totem. Up to three teams, each with 2 to 6 players, can embark on this adventure simultaneously, lasting around an hour.

The Shelter opts for a wintery, immersive atmosphere: lost in the woods, players have one hour to find a cabin and unlock its door by searching the surrounding area for essential objects. It's a race against time in the heart of nature, with teams of 2 to 6 players. In both cases, advance booking is mandatory through atoutbranches.com.

Mini-golf in the forest: the next big trend for 2026

In 2026, the park will also debut a 12-hole mini-golf course set within the wooded landscape, offering fun for all ages and seamlessly blending with other activities. Playful and laid-back, this new addition was made possible through collaborations with local partners from Milly-la-Forêt, including Krys, Bricomarché, La Halle du Chocolat, and Les Délices Fromagers. It's the perfect way to wind down after a day of exploration, with a game of mini-golf under the trees and a racquet in hand.
