You need to book tickets for attractions in advance
One of the most important Spain travel tips that Toplist would like to share with you is to book your tickets for attractions and activities in advance, regardless of the season. That means you need to book tickets for attractions in advance. The reason is that, even if you think visiting Spain in the off-season is a good idea, many attractions need to be booked up well in advance. For example, tickets to Granada's renowned Alhambra frequently sell out months in advance, which can be a major inconvenience if you are traveling on the spur of the moment.
Furthermore, the most popular restaurants in cities such as Barcelona and Madrid require reservations and are frequently packed. You can certainly leave some room for spontaneity on your trip, but you will be much happier if you visit Spain with the big-ticket items pre-booked. This is actually one of the things to know before traveling to Spain that you should remember!
