The mixture of cultural traditions has generated substantial diversity in folklore, cuisine, music, and literature, particularly the latter, given the literary contributions of Nicaraguan poets and writers such as Rubén Darío. Known as the "land of lakes and volcanoes", Nicaragua is also home to the Bosawás Biosphere Reserve, the second-largest rainforest of the Americas. The biological diversity, warm tropical climate and active volcanoes make Nicaragua an increasingly popular tourist destination.
