Here's another way to go beyond the usual hotspots while traveling: Dive down about 30 feet (9.1 meters) and explore the plants and animals of your destination's shores and reefs. Generally, because you're presided over by a scuba service and attached to an oxygen supply, you don't have to be the best swimmer, and can focus on exploring rather than staying afloat. Belize's Barrier Reef is warm year-round and home to friendly manatees that reportedly swim close to divers. Koh Tao is a party destination for young revelers around the world, but its reef offers a large population of white sharks. And of course, you could also check out Australia's Great Barrier Reef, technically the largest living structure on Earth.
