Ho Chi Minh City is one of Southeast Asia's best bases for day trips. The Cu Chi Tunnels are an hour northwest on good roads. Tay Ninh, with its extraordinary Cao Dai Great Temple, is another hour beyond that. Vung Tau — a beach resort on the South China Sea — is the closest beach to the city and a popular weekend escape for Saigonese. The Mekong Delta, Vietnam's rice bowl, begins just two hours south: My Tho is the nearest delta town, but Can Tho deeper into the delta is worth an overnight.
