"This Hawaiian locale is the perfect place to see the black rocks and crystal lagoons the Big Island is famous for. Not your average sandy stretch, Carlsmith Beach is a grassy, tree-filled park overlooking brilliant lava-ringed lagoons. The clear, turquoise waters here are protected by a reef, making the area a snorkeling hot spot. An abundance of sea turtles adds to the unique experience of this magical habitat. Pack your lunch and picnic at one of the on-site tables in the shade of a palm tree." - Travel + Leisure Editors
