Tenerife

Tenerife claims the crown for altitude and year-round warmth, as Mount Teide's 3,718-meter peak dominates the skyline and creates microclimates across the island. With an average winter temperature of 21°C, it is warmer than the typical rival, making it a top winter-sun destination. The 3,000-meter drop from Teide's summit to the southern beaches hosts 4 million annual whale-watching trips, a number that outpaces Mallorca's 1.2 million. More than 70% of visitors choose the southern resorts like Los Cristianos for consistent sunshine, yet the island's six distinct ecosystems—from lunar lava fields to laurel forests—offer variety that outperforms #3's more limited landscapes.
