Get back to nature in the volcanic landscapes of Terceira Island on an approximate 2.5-hour hike along the Mistérios Negros trail. Benefit from pick-up at your hotel in Angra do Heroismo or Praia da Vitória, and then make your way to the start of the trail. Set off on a moderate level circular trek of 5 kilometers to see different landforms created by the ancient lava flows. Encounter small lakes and volcanic domes, along with the Pico Gaspar climb up a volcano that erupted 15,000 years ago. Called Mistérios Negros due to the dark lava rock surrounding the area, the area is not to be missed. Follow the trail through different vegetation, including Japanese cedar, juniper and blueberry plants. Keep a look out for the local birdlife as you fill your lungs with fresh country air.
