TOP SECRET: Underground Tunnel & Bunker Tours

Beneath the streets of Cape Town lies a hidden world most visitors never know exists. Step below the surface into a network of tunnels and bunkers built into a historic fort dating back to 1795 — a site that once played a real and active role in South Africa's military history, and still carries that atmosphere today.

On this tour, you'll wind through original underground tunnels and bunkers, step inside a decommissioned ammunition magazine, and see first-hand how vintage ammunition lifts once operated to move shells through the fort. The highlight for many visitors is coming face to face with the only disappearing gun left in South Africa — a rare feat of military engineering that few get to see up close.

Once you've explored the depths, resurface for refreshments at the atmospheric "Sergeants Bar," the perfect setting to hear the stories that bring this site to life. Learn about the secret radar stations that once monitored the coastline, and the gripping history of German U-boats that sank over 100,000 tons of shipping in Cape waters during the war — a chapter of local history that's often overlooked.

Allow around 2 hours to fully take in this immersive underground experience. Tours are available privately or as scheduled group sessions, making this a genuinely unique outing for a wide range of occasions. It's an unforgettable venue for corporate team-building days, bachelor parties, treasure hunts, Halloween events, or a fully themed Secret Agent–style escape tour.

Whether you're a history buff, a curious local, or looking for something different to do in Cape Town, this tour offers a rare glimpse into a hidden military past most people walk right over without ever knowing it's there.

Booking well in advance is essential, as spaces fill quickly.
