I personally like Sorkheh Hesar National park, it can get very crowded on holidays or weekends but best time to go there is weekdays, Weather is so good and clean, there is bicycle-way in almost all roads of park, there is some spots for camping, also near those spots you can find barbeque. But never try to camp a fire because it can get dangerous very fast.

Niavaran park, its a public park in north of Tehran at Niavaran district and its situated at south of the Niavaran Palace Complex.
This park is built by latest Shah of Iran, Mohammad Reza Shah.
Its a beautiful park full of trees. The weather there is colder than rest of city. This park has a beautiful fountain and there is a playground for children. It can get very crowded most of times.

Very cheerful and peaceful place to spend with my wife.
