Zemplén is in Northern Hungary.
Zemplén is a historical region of Hungary and also a mountain range in the far North of the country.
Sárospatak and Sátoraljaújhely are on the same railway lines. Regular train service from Miskolc is available (1 and a half hour). There are 5 trains day that goes directly to both cities from Budapest (4 hours).
By car the fastest way is on motorway M3 then on route 37. Both cities are on this road.
Smaller towns and villages can only be reached by bus. Mostly the buses start from the two cities in the region.
There are inns and csárda (country inn in Hungarian) with the usual Hungarian menu in the region. In Sárospatak there are few good pizzerias.
Just next to the region Anyukám mondta  is one of the best restaurants in Hungary (Encs). Rustic Italian food with original Italian ingredients and with a fantastic Italian coffee.
As Tokaj is just south of the region, good wine is plenty and widely available.
