The largest of the Canary Islands, Tenerife tempts travelers with its mountainous landscape, 165 miles of shoreline and welcoming weather year-round. Dig your toes into the sand at idyllic beaches, hike among the vegetation and lava flows in Corona Forestal Nature Park, enjoy a dip in saltwater pools at Lago Martianez or discover local history and culture in San Cristobal de la Laguna, a UNESCO World Heritage Site. In Teide National Park, take in panoramic views on a cable car ride up Mount Teide, a dormant volcano. From the gondola station, try the challenging, roughly 40-minute trek to the 12,198-foot summit to stand on the highest point on Spanish soil. In February, a huge pre-Lent carnival celebration takes place on the island.
