With so many Spain tourist attractions to chose from, this list could easily have been a top 40 countdown of the top destinations. Nevertheless, here are some of Destination360's best suggestions for your next trip to the Iberian Peninsula

Run with the bulls in Pamplona

Channel you inner Hemingway during the Fiestas de San Fermin. In this, the most storied of Spain tourist attractions, six bulls are released into the narrow cobblestone streets of Pamplona each morning during the week of July 6 to July 14; in front of the bulls hundreds of locals and tourists from around the world test their daring by running in front of, next to (and sometimes under) the careening bulls. The whole event provides some of the best Spain sightseeing, and the entire week of festivities is the highlight of adventure tourism in Spain.

Party all night (and all morning) in Ibiza

Increasingly, tourism in Spain has become synonymous with the island of Ibiza, and for good reason—you come to Ibiza to party. Indulge your hedonistic side as you dance the night away in some of Europe's hippest clubs. Take the raucous Disco Bus from club to club and dance and drink from Midnight to well-past 6 am in this most frantic of Spain attractions.

Tour the Basque Country

The Basque Country or Pais Vasco, is an area north of Madrid bounded by the Pyrenees Mountains and the Bay of Biscay. This unspoiled and easily traversed landscape is among the best tours to Spain for those seeking a quiet, quaint, old world getaway.

Visit the Prado

Madrid's premier tourist attraction, and one of a handful of must-see Spain tourist attractions, the Museo del Prado houses one of the oldest and most prolific collections of art in the world.

Relax at Parc Guell

Laid out on hill with breathtaking views of Barcelona, the Parc Guell (Guell Park) was Antoni Gaudi's most ambitious project after the Sagrada Familia church. Though commissioned as a private housing complex, only two houses were every built on the site. What remains, can only be described as the most psychedelic of Spain attractions. Twisting ceramic benches, a vast hall of pillars, giant lizards and sloping pathways all provide an amusement park feel.

Las Fallas in Valencia

Tours to Spain wouldn't be complete without a trip to Valencia during the Fiesta de Las Fallas. From March 12 to 19 the city of Valencia is a pyro's dream come true. From the minute you step off the train, firecrackers are popping at your feet, as giant Papier Mache effigies or fallas are paraded through the streets, judged, and awarded prizes. At night free firework shows light up the sky, while the days are filled with bullfights and paella eating on every street corner.

The Alhambra

Any trip to the south of Spain must include a stop in Granada and a tour of the Alhambra. Composed of three distinct groups of buildings on the Alhambra Hill, the complex is essentially a palace with extensive gardens surrounded by a fortress. This national monument is one the most mythical and romantic Spain attractions.

Ramble along Las Ramblas

Tourism in Spain is not all festivals and bullfights. Travelers looking for a low-key Spain sightseeing option can stroll along Barcelona's main street: The Ramblas. This leafy avenue is lined with cafes and newspaper stalls and is a favorite stroll for locals and tourists alike.

Donana National Park

Tours to Spain are incomplete without a trip through this untracked National Park. One of the last areas of true wilderness in Europe, the Donana National Park in western Andalusia is filled with wetlands, 150 species of birds, wildlife in abundance and the endangered imperial eagle and lynx.

The Guggenheim in Bilbao

Described as the the greatest building of our time, this Frank Gehry-designed postmodernist museum attracted 1.4 million viewers in it first year alone. Once inside, art lovers are treated to a host of twentieth-century masterworks from artists including Picasso and Rothko.
