Tenerife is regarded as the "island of eternal spring. The trade winds assist the island in maintaining a perfect temperature and create 'A Sea of Clouds,' a natural phenomenon in which clouds gently push against the hilltops, causing air moisture to condense. The rich culture of Tenerife has been heavily influenced by Spain and the Guanches (the indigenous group who originally inhabited the island). Additionally, historical influences from Europe, Africa, and the Latin Americas have shaped the island's towns, villages, and festivals. This fusion is particularly evident in the island's architecture, cuisine, and local traditions. Tenerife also hosts the world's second-largest carnival celebration in terms of magnitude and spectacle, trailing only Rio de Janeiro. The 14-day celebration attracts visitors from all over the world.
