Tenerife is the biggest and most complete choice, with the bulk of Spain's tallest peak, Teide, dominating the interior and a lively, built-up south coast built for resort life. Its twelve all-inclusive hotels span 81 to 192 EUR a night with an average rating of 8.8, and the range - from the classic La Laguna Gran Hotel to the contemporary Barceló Santa Cruz Contemporáneo and the more intimate Hotel Taro Santa Cruz - shows an island that covers every style without you needing to compromise.
Gran Canaria pairs the famous dunes of Maspalomas with the most varied landscape of the four islands, from green ravines to desert-like scrubland, and backs it with the region's strongest nightlife. It also posts the highest average rating in this ranking, 8.9, across a 90 to 242 EUR range that includes Suites 1478, the boutique Cordial Plaza Mayor de Santa Ana and the golf-and-spa-led Salobre Hotel Resort & Serenity.
Fuerteventura and Lanzarote are the quieter, more distinctive picks. Fuerteventura is built around genuinely endless white-sand beaches, near-constant wind and some of the best watersports conditions in Europe, with hotels such as AVANTI Lifestyle Hotel, Playitas Hotel - Sports Resort and HD Lobos Natura Fuerteventura pitched at 123 to 307 EUR and an 8.7 average. Lanzarote trades beaches for volcanic drama and design, favouring low-rise, adults-recommended boutique hotels like Finca Isolina, Palacio Ico and La Isla y el Mar, priced 127 to 259 EUR with an 8.8 average.
