Nature in Portugal swings from Atlantic surf to volcanic crater within the borders of one small country. The mainland offers mountains, river valleys, and a wild ocean coast, while the islands of Madeira and the Azores add laurel forest and lava-formed lakes far out at sea. To explore nature and outdoors in Portugal is to move through this astonishing variety, from a granite mountain range to a southern lagoon to a crater lake in the mid-Atlantic. For a nation of its size, Portugal holds an outsized share of landscapes.

Geography spread the gifts wide. The mainland rises to the Serra da Estrela, the highest range on the Portuguese mainland, while the Peneda-Gerês National Park guards wolves and ancient oak in the green north. The Douro carves its terraced valley inland, and the southern coast keeps the lagoons of the Ria Formosa and the cliffs of the Algarve. Out in the ocean, Madeira's famous levada water channels thread through laurel forest, and the Azores cradle volcanic crater lakes like those of Sete Cidades. Nature in Portugal stretches from mountain to mid-ocean.

Today the open air rewards every kind of explorer. The best nature and outdoors in Portugal span hiking the Serra da Estrela and Peneda-Gerês, walking the Madeira levadas, and exploring the Azores craters and the Algarve coast. Visitors searching Portugal outdoor tours or top nature experiences will find guided hikes, island treks, and coastal walks. Among the restorative things to do in Portugal, a levada walk through Madeira's forest stays with you for years. The country is small, but its wild side reaches from the mountains to the middle of the Atlantic.
