The Best Walking Tours in Berlin (Updated 2025)
"I found Berliner Unterwelten’s tours fascinating because they literally take you under the streets to explore Cold War and World War II–era bunkers, the few remnants of Germania that Hitler envisioned, and sub‑terrestrial tunnels used for secret purposes—including tunnels dug under the Berlin Wall; tours start from around 16 EUR." - Matthew Kepnes
