Discover Nantes with the outdoor Jules Verne escape game, a 2-hour adventure combining puzzles and city exploration for around $17.80 per person.
This outdoor escape game, “Jules Verne – The extraordinary challenge,” offers a unique way to explore Nantes. Priced at $17.80 per person and lasting approximately 2 hours, this activity combines a treasure hunt with the thrill of solving puzzles in an urban setting. The tour departs from Les Machines de l’Île and ends back at the same point, making it a convenient circular experience. It’s designed for groups, with group discounts available, and it features a mobile ticket for easy access.
The activity is suitable for those who enjoy interactive outdoor adventures and do not mind moderate physical activity. Its modern, tech-driven approach relies on a charged smartphone with internet access and basic supplies like a notebook and pencil. While the experience is engaging, some reviews note that the puzzles may not provide much educational insight into Jules Verne or the city’s history, making it more of a fun challenge than an educational tour.

The adventure kicks off at Les Machines de l’Île, a vibrant hub in Île de Nantes known for its giant mechanical creatures and artistic displays. From this central location, players receive their initial access code through a chatbot to begin the mission. The start is straightforward, with clear instructions provided for participants to dive into their adventure.
The meeting point’s proximity to public transportation makes it accessible for most visitors, and the entire experience is designed to be self-directed once underway. The activity finishes right back at the starting point, adding convenience for those with tight schedules or plans to explore further.

Throughout the walk, players observe their surroundings for clues, interact with their digital guide, and work closely with teammates to piece together the story. The puzzles are described as “sharpening” and requiring receptiveness and quick thinking, making it an engaging challenge for those who enjoy a mix of adventure and mental agility.

This activity necessitates only a charged smartphone with internet access, ideally one per player, to access the chatbot and solve puzzles.
