Cu Chi Tunnels
Concierge.com's insider take:
It's difficult to regard the orderly rubber trees and rice paddies and realize this rural landscape 40 miles northwest of Saigon was the most heavily bombed, gassed, and defoliated target in the history of warfare. Through a labyrinth of underground passageways and rooms, Vietcong rebels were able to control this rural area, emerging from trapdoors at night to lay booby traps or ambush patrols, then retreat to well-equipped lairs 30 feet below the surface that could withstand B-52 air strikes. A section of the 150-mile tunnel network has been developed and, thankfully, enlarged (the original passages were barely 18 inches wide and 30 inches tall). Saigontourist, along with every private tour company in town, offers a half-day tunnel excursion, usually with hotel pickup and return (84-8-829-8914; www.etravelvietnam.com). You'll find displays of gruesome booby traps, a screening of a heavy-handed 1967 North Vietnamese propaganda film about a pretty Cu Chi peasant girl turned "American-killer hero," and several winding, lengthy tunnels to navigate (flashlights are provided). And for an extra $13, you can squeeze off a ten-round clipthe munitions menu includes a choice of M16 or AK-47 riflesat the on-site firing range. Go as early as possible to avoid Ho Chi Minh City rush hour traffic and tour-bus crowds.
