If you are asking yourself this question, it is because you don't know Valencia yet, and if you don't know Valencia, you are missing something important...
Not because it is the third largest city in Spain, founded by the Romans, occupied by the Muslims and reconquered by the Christians, which could perhaps indicate the richness of the historical and monumental heritage of its historic centre.
Nor because it is bathed by the Mediterranean Sea and has beaches presided over by blue flags and awarded with recognitions such as the Q for Tourist Quality, where you can sunbathe on the sand, dive into the refreshing water, play volleyball, pedal on a scooter in the open sea, enjoy an ice cream, go for a catamaran or boat ride, take a sailing course, paddle surf, kite surf, or "anything surf"....
Nor because there is a multitude of ideal areas to go out and have a drink at nightfall in one of the fashionable bars, dance until dawn in the most select discotheques and enjoy "the Moon of Valencia"...
Nor because you can enjoy the best gastronomy, including, of course, rice in any of its varieties, paella, black, a banda, duck, seafood... Because the signature Mediterranean cuisine is unbeatable and the quality in Valencia's restaurants is a must. Not to mention the fact that you can enjoy tapas and a beer in any beach bar while you enjoy the sea breeze, or in any bodega in the city as you stroll through it.
Nor, of course, because it is the third best positioned Spanish city in Trivago's ranking of online reputation worldwide, with 81.64 points out of 100, and with more than 200,000 ratings.
Valencia is always good and simply because you can't miss it. There may be a few reasons why you shouldn't visit Valencia that only you would know, but there are thousands more why you should.
COME.
