What is the Green Mountain Adventure Challenge?

The Green Mountain Adventure Challenge (GMAC) is a multi-day, real-world quest rooted in the history and landscapes of Vermont’s Green Mountains. Unlike typical outdoor activities, it emphasizes interactive storytelling and puzzle-solving. You and your team will decode clues, explore ancient valleys, and learn about the area’s past—all while engaging with the environment in a meaningful way.
This isn’t a race. The tour is designed to be open-ended, giving you the freedom to take as much time as needed. The goal? To uncover the hidden story of a secret world and arrive at an unexpected surprise at the end. It’s a combination of physical exploration and mental challenge that appeals to adventurers who enjoy problem-solving and historical discovery.
How does the itinerary work?

The adventure officially starts at the meeting point: 108 Vermont Rte 100, West Dover. From there, the journey unfolds through a labyrinth of clues scattered across Vermont’s scenic valleys and mountain trails. You’ll encounter signs, landmarks, and possibly relics that form part of the puzzle.
What makes this self-guided format appealing is that you control the pace. The average time reported is 2-3 days, but you’re free to take longer if you wish. The route and activities are designed to be flexible, meaning you can pause, reflect, or revisit clues as needed.
The tour concludes back at the starting point. There’s no predetermined schedule, but the experience is meant to be an immersive journey into the history and mystery of Vermont’s landscape.
What can you expect during the adventure?

Expect to wander through ancient mountain valleys, each holding stories and signs that could unlock the next clue. The puzzles are described as mind-bending, so some level of curiosity and patience will serve you well.
The challenge involves more than just walking — it requires keen observation and teamwork. Reviewers mention that each encounter and sign might be the key to your next step, emphasizing the importance of attentiveness. You might come across historical tales or intriguing artifacts as you go, making each discovery rewarding.
We loved how one reviewer said that it’s a real challenge based in real history with real outcomes, which adds a meaningful layer to the fun. The activity also encourages exploration of Vermont’s natural beauty, so be prepared for scenic vistas and fresh mountain air.
