Most tourists use Puerto Barrios as a gateway to Livingston or Belize since there's not much to see here, but just out of town a very pretty waterfall, Las Escobas, has a good swimming hole at its base. You might also want to visit Punta Manabique, a long point of land with mangroves and swamps jutting out into Amatique Bay, or hike in the rainforests of Cerro Gil. All around this area, there's good bird-watching and nature-viewing, which you can enjoy on hikes or boat rides. For tours or other information, ask at your hotel.
Fishing, snorkeling, and scuba diving are popular at the nearby Belizean cays. If you want to do any tours or activities while you're in the city, ask at your hotel, or check in with the folks at Amatique Bay Resort and Marina.
