Land of volcanic drama, staggering sunsets, and some of Spain’s most diverse terrain, Tenerife is vying to be the adventure capital of the Canary Islands. The colossal, dormant volcano Mount Teide—together with the red-tinted rocks and barren landscapes of Teide National Park, a UNESCO World Heritage Site—is one of Tenerife’s top draws: Hike, drive, or take the Teide Cable Car to the top of the volcano for stunning views of Orotava Valley and the crater of Mount Chahorra. Santa Cruz de Tenerife, the island’s lively and culturally rich capital, boasts bars, museums, and shops, and serves as a launchpad for day trips to La Gomera, an unspoiled Canary Island home to Garajonay National Park and Masca Valley. From Playa de la Americas, whale- and dolphin-watching trips are a popular choice with naturalists; while Costa Adeje proves the perfect place to snorkel with turtles or learn to scuba dive amid submerged caverns. The popular resort towns of Los Cristianos and Los Gigantes appeal to travelers looking to relax with pretty marinas and golden beaches. Explore the quaint town of Puerto de la Cruz on a Segway, see the island from above on a paragliding flight, or soar out to sea on an extreme jet ski safari—no matter how you explore Tenerife, the island never fails to impress.
