Hogwarts is one of the best schools in the world. The best way to go there is to catch the train "Hogwarts Express" which is in King's Cross Station, the platform 9 ½, there is just across the wall that divides the platform 9 and 10.
Hogwarts was founded long ago by the world's greatest wizards: GodricGryffindor, Helga Hufflepuff, Rowena and Salazar Slytherin Rawenclaw.It is the safest place in the world after Gringotts, the wizarding bank. You can not Apparate at Hogwarts as Dumbledore and all other directors cast a spell anti-Apparition.
