The Teide National Park is located at the heart of Tenerife and is the location of Mount Teide, Spain’s highest mountain and the highest volcano in the Atlantic Ocean islands. You can hike to the summit, or take the cable car and explore at the top. The mountain is more than two miles (3,718 meters) high, measured from sea level, so the summit isn’t recommended for children under 3 or pregnant women due to the high altitude.
