Because Spain and its neighboring islands have over 40 airports, one of the best ways to travel around Spain is by plane. If you are departing from either Madrid Barajas or Barcelona El-Prat you are going to find several flights to destinations all over the country, but you will also find plenty of flights between some of the smaller cities in Spain. Renfe is the national train network of Spain and they offer regular service throughout the country on a combination of high-speed, normal-speed, and suburban train lines. Travelers find that this train system is both efficient and reliable and you can even take trains from Spain into the neighboring countries such as Portugal and France. If you will be traveling a long distance in Spain, one of your best options is to book one of the high-speed trains called the Alta Velocidad. As you get into smaller cities and towns in Spain that is when you'll begin to find more normal speed and regional trains that make efficient and on-time trips but in a slower timeframe. Another option for travel around the country is on their extensive bus network. This method of travel will not be as quick as flying or taking a train and often is not quite as comfortable, but it is one of the most affordable ways to travel throughout Spain and it can get you to some of the smallest towns in the country. The country of Spain has a large network of motorways and toll roads. Because of this great network of roads, Spain is a good country to rent a car and do travel on your own time.
