This tour starts in front of a rare WWII Douglas C-47 Skytrain aircraft, which acts as a striking photo opportunity and an introduction to the site. You’ll get the chance to climb aboard the aircraft, a rare experience for aviation buffs or history lovers. It’s an excellent way to set the tone for the adventure ahead, blending history with hands-on exploration.

Next, you’ll move to the runways, where your group will drive slowly across these vast, deserted stretches. It’s easy to imagine what pilots experienced as they took off from this clandestine base. The views are impressive, especially as you catch sight of a plane-shaped hole in the hill, hinting at the massive underground structures that lie beneath.

The heart of the tour is the visit to the tunnels, which stretch about 3 kilometers underground. Here, you’ll step into a different world—dimly lit, cool, and echoing with stories of wartime activity. You’ll be provided with strong flashlights (included), as you walk through the dark corridors, discovering everything from construction details to the lives of the personnel who worked there.

Guides like Antonio are praised for their deep knowledge and storytelling prowess, sharing personal, often insider, stories of the base’s operational days, staff relationships, and conflicts. As one reviewer noted, Antonio “brought the place to life,” making history accessible and engaging through his stories.

The tunnels reveal a complex network that was once a hub of secrecy and tension, shaped by rising Cold War fears. You might get a sense of how rising international tensions could divide colleagues of different nationalities, a poignant reminder of how geopolitics can influence personal lives.

The tour wraps up back at the airplane, where you can reflect on what you’ve seen and learned. The entire experience lasts around 3 hours, making it a manageable yet thorough exploration.

Walking through the dark tunnels is the tour’s most immersive moment. You’ll traverse narrow passages, some with damaged sections, which is why appropriate footwear is recommended—think sturdy boots rather than sneakers. The tunnels are cool and dark, so carrying a strong flashlight (provided) is essential.

Guide-reviewed safety protocols are explained before entering, ensuring a safe experience, though you should note that this activity isn’t suitable for people with claustrophobia, respiratory issues, or wheelchair users.

Many visitors appreciate the detailed storytelling about the construction, operation, and eventual destruction of the base. You’ll learn about the relationships among employees, how the base functioned during its heyday, and the stories of conflict—adding a layer of human connection to the otherwise stark environment.
