Because of the unique locality of Pécs you simply cannot get lost in the city. If you go down from the hill sooner or later you will find the city centre. But if you are willing to spend some time in the untroubled nature, all you have to do is to go up the hill.
The Mecsek hill which is surrounding Pécs is a harmonic place to visit during the whole year. On the top of it you will find the TV-tower, with a restaurant and an amazing view at the city. Who is willing to find the nature inside the city must go to the Botanical Garden of the University (6 Ifjúság Street). It is a little island of harmony within the civilization. The Tettye ruins are telling the story of the renaissance. Unfortunately the palace did not remain hereanymore but the green area around it has been recently renovated, making it an ideal place to take a walk among the ruins, especially at night when you can have a magical view at the whole city. If you don't mind taking a bus, Lake Malomvölgy or Lake Orfű are the best places to visit to be near the water, especially in summertime. In Lake Orfű you can also swim, however, Lake Malomvölgy is only for fishing or hiking/running/biking on the route around the lake.
Getting closer to the nature might involve living animals too; in this case you should definitely visit the Pécs Zoo is under construction currently, according to the operator it will be able to welcome guests again by the middle of 2015.
