How to Do It Right
Navigating Tunnel Worlds
Target weekdays for open tunnels and peak foot traffic; check official maps from downtown associations for current hours, as many close weekends. Start at major access points like skyscraper lobbies. Book guided tours for first-timers to uncover hidden branches.
Wear comfortable shoes for uneven floors and stairs; download offline maps since signals weaken underground. Pace yourself with breaks at food courts. Respect posted rules on photography and loitering.
Practice reading multi-level signage for quick orientation; no special gear needed beyond basics. Go solo with a tunnel app or join free walking groups. Venture off main paths for quiet retail nooks.
