Sorkheh Hesar National Park protects dry hills and open country on Tehran's eastern edge, a reminder that the metropolis still presses against wild land. The landscape is not lush, but it has room, long views, and wildlife habitat in a city where green space can feel rationed.
It is most appealing to travellers who have already seen central Tehran and want an outdoor reset without committing to a full mountain excursion. Go early, take water seriously, and treat it as a semi-wild edge of the capital rather than a manicured urban park.
