Discover the adventure of mining your own opal at Querétaro’s active Opalo el Pilon Mines—guided by experienced miners, with hiking and authentic regional insights.
Are you someone eager for a hands-on experience that combines a bit of nature, a dash of history, and a whole lot of fun? This tour at the Opalo el Pilon Mines in Querétaro promises just that—an authentic chance to learn about opal formation, explore an active mine, and even mine your own gemstone. While it’s a short, three-hour outing, it offers a surprisingly rich peek into mining life that might just surprise you.
What we love about this experience is its interactive nature—you’re not just a spectator, but a participant. Plus, the guided tour by a seasoned miner provides genuine insights into the craft and regional flora. The only caveat? It’s a physically active outing, with hiking involved, so comfortable shoes are a must. This tour suits those who enjoy a bit of adventure, are curious about natural processes, and don’t mind getting a little dirt under their nails.
If you’re traveling near Querétaro and looking for an affordable yet memorable activity that offers more than just sightseeing, this could be a perfect choice. It’s especially ideal if you’re interested in geology, regional plants, or simply want to try your hand at gemstone mining in an authentic setting.


If you’re craving a unique, tactile experience that pulls you away from typical tourist spots, this three-hour mining tour ticks many boxes. Located in Querétaro, in the Mexican state of the same name, the activity revolves around an active opal mine. What makes it stand out is the chance to mine your own opal—and keep whatever you find. It’s an appealing way to turn geology into a tangible souvenir, especially for those interested in gemstones or natural history.
Your journey begins with a 15 to 20-minute hike through regional scenery, which offers an opportunity to appreciate the local flora and fauna. This gentle trek sets the tone for the adventure ahead, and we found it a lovely way to transition from the outside world into the underground experience.
Once at the mine, you’ll be equipped with tools—an important detail because it transforms the activity from a simple “look, but don’t touch” tour into a hands-on mining experience. Guided by a miner, you’ll learn about opal formation, which involves natural geological processes that occur over millions of years. This background makes your gemstone feel more meaningful—you’re not just digging randomly, but understanding a natural process.
The actual mining process is unlimited in time—meaning you can take as long as you like to sift through the material and try to find your gemstone. As one reviewer pointed out, “the activity includes unlimited time to mine, which is generous and makes the experience less rushed.” You might find that time slips away as you enjoy the quiet thrill of discovery.
Many reviews emphasize the authenticity of the experience, with the guided miner sharing insights into regional medicinal plants and local ecology. This educational component adds depth, turning the activity into a mini geology and botany lesson rolled into one.
The cost of $11 per person is remarkably reasonable, considering how personalized and tactile the experience is. It’s a great value, especially since you get to keep whatever you find. This can be particularly rewarding—you might walk away with a beautiful gemstone that’s genuinely yours.
To maximize your time at the mine, bring comfortable shoes suitable for hiking, a sun hat for protection during the outdoor walk, and casual, comfortable clothing. Since the tour is outdoors and involves some physical activity, these simple preparations can make a big difference.
The tour is conducted in Spanish, so some familiarity with the language or a guide app could enhance your understanding. The activity is not suitable for people over 95 years old, mainly due to the physical requirement of hiking and mining. Also, alcohol and drugs are not permitted, ensuring a safe environment for all participants.
