What Is This Tour All About?
This isn’t your average city tour. Instead, it’s a mission-style adventure where you’re tasked with protecting Porto’s heritage from the fictional threat of spies from the secretive GLOOM organization. The goal? To solve clues, decipher riddles, and discover hidden spots around the city—all while keeping Porto’s charm safe from espionage. It’s a playful, story-driven way to learn about the city’s highlights, with the added twist of a secret mission.
How Does it Work?
Once you book, you’ll receive a confirmation code via email, along with instructions. The adventure kicks off at the Coliseu do Porto, where you find a QR code to scan using your phone. This step is essential—your mobile device becomes your mission control. From there, you’ll follow clues that lead you through key landmarks, including top attractions and some lesser-known corners that even locals might not know.
The activity lasts approximately 2 hours 30 minutes, but you’re encouraged to go at your own pace. Whether you want to speed through or take your time exploring, the flexible timing means you can customize your experience. The route finishes back at the starting point, Armazém 93.
What’s Included and What to Expect?
You can expect a mix of clever riddles, surprising installations, and interesting puzzles designed to challenge your curiosity. The clues are crafted to make you think and observe, encouraging teamwork whether you’re with friends, family, or a small group.
A highlight for many is the chance to see Porto’s most famous landmarks through a different lens. The clues often lead to stunning views and hidden corners, giving you a more authentic feel of the city. As one reviewer mentioned, “We really liked the game, the clues are fun and challenging, and the courses are quite interesting.”

What Makes It Special?
The main appeal is the interactive element. Instead of passively looking at sights, you’re actively engaged in solving puzzles that reveal stories and secrets of Porto. This makes the tour more memorable and fun, especially for those who love a challenge.
The experience is also great value. For approximately $22 per person, you get a multi-faceted activity that combines sightseeing, problem-solving, and a bit of adventure—all at your own pace. Many reviews point out how enjoyable and well thought out the clues are, making this a rewarding way to spend part of your Porto trip.
What Could Be Better?
A common concern is the reliance on good weather. Since the entire activity is outdoors, rain can derail the fun, or at least make it less comfortable. Also, it’s not designed for people with special needs, so keep that in mind if traveling with mobility challenges.
Plus, one review highlights a failure in execution, with the event not taking place due to no staff being present. While this seems to be an isolated incident, it’s worth noting that sometimes logistical issues can happen, so checking recent reviews or contacting the provider beforehand might be a good idea.
Who Will Love This?
This experience really shines for adventurous travelers who enjoy puzzles and storytelling. It’s perfect if you want to explore Porto in a more engaging way beyond the usual walking tour. It’s also suited for small groups looking for a private experience or for families with older children who can handle the walking and the riddles.
If you’re traveling solo, it could still be fun, especially if you enjoy meeting like-minded people during group activities, but it’s primarily designed for private groups.
The Price and Its Value
At less than $25, the tour offers a good bang for your buck. It’s a hands-on activity that mixes sightseeing with mental challenges, providing more depth than just walking around with a guide. It’s not a typical tour—there’s no lecturer or large group—and the focus on self-guided discovery makes it feel personalized.
However, it’s worth considering that if you’re expecting a highly structured experience, this one’s more freeform and relaxed, which might not suit everyone’s taste.
Final Thoughts

If you’re after a unique way to see Porto that combines adventure, discovery, and a touch of storytelling, this “Hidden Valley” mission could be a perfect fit. It’s especially suited if you appreciate puzzles, enjoy exploring hidden corners, or want an activity that breaks away from traditional sightseeing routes.
This tour is best enjoyed in good weather and with a group that’s enthusiastic about interactive experiences. It’s affordable, engaging, and offers a fresh perspective on Porto’s well-loved sights. Just be prepared for some outdoor walking and the need for a mobile device, and you’ll likely find it a memorable part of your trip.
