Fly into Tenerife South, breeze through, rent a tiny car, roads climb fast. First hit Playa de las Teresitas, north side, golden sand shipped from Sahara, palms lined, calm bay for lazy swims. Locals grill fish weekends, join in, bring beer. But real black sand magic's west, Playa de los Gigantes, massive cliffs drop straight into Atlantic, waves pound dark grains, surfers ride barrels. Sunset from here turns cliffs orange, water ink.

Core of the island? Teide, dormant beast, 3718 m, snow cap in January, flip flops in July. Drive up from sea level, pine forest gives way to moon rock, altitude kicks lungs. Park at base, cable car whisks you 2000 m quick, last 163 m hike permit only, book months ahead. Summit smells sulfur, views stretch to Gran Canaria on clear days. Mid way stop, Roques de García, weird lava fingers, short loop trail, photos look Martian. Night option, guided astro tours, telescopes on blankets, Milky Way spills like cream.

South west, Masca valley, road hairpins scare rental agreements, but village at bottom worth it. Stone houses, palm groves, hike the gorge 3 hours down to tiny beach, boat pickup only way back, book ahead. Water icy Atlantic, pebbles black, cliffs tower 600 m, feels end of world.

North east, Anaga mountains, laurel forest dripping moss, clouds snag peaks. Taganana village, black sand cove, waves big, surfers only. Hike Cruz del Carmen to Punta del Hidalgo, 4 hours, ocean crashes below, goats block path. Lunch in Chinamada, cave restaurants, goat stew, wine from plastic jugs.

Food shifts by altitude. Coastal, papas with red mojo, octopus grilled. Up high, conejo en salmorejo, rabbit in garlicky sauce. Guachinches, pop up home restaurants, house wine, bench tables, cash only, ask locals.

Stay weird. Parador in Teide park, old school, fireplaces, wake to volcano view. Masca hamlet fincas, no wifi, stars your tv. Los Gigantes cliff side apartments, pool hangs over drop. Avoid mega hotels unless buffet calls.

Quick hits: whale pilot tours from Los Gigantes, 3 hours, pods year round. Loro Parque north, penguins in heat, orca shows, ethical debates, you pick. Carnival Santa Cruz February, bigger than Rio some say, book year early.
