First, there is Spanish Spanish, as in Spanish as spoken by Spaniards. It's somewhat different than Latin American Spanish. Of course, Latin American Spanish itself is further broken down into various varieties.

From what I understand, even within Spain, there are different dialects of Spanish Spanish, such as Castilian, Andalusian, Extremaduran, etc.. Reportedly, Castilian is one of the most famous dialects.
