The development of urban area was accured quickly and lead to many environmentalproblems such as the rising of temperatures and decreasing of environmental quality. Greenopen space (RTH)was needed to overcome those problems.  The objectives of the researchwere to figure out the characteristics of vegetation in Patriot Bina Bangsa Urban Forest(including the species, density, broad canopy coverage), to figure out comfort index ofPatriot Bina Bangsa Urban Forest and to find out the visitor’s perception about comfortsvalue of facilities.  The analysis of vegetation was employed as the method of data collectionsensus method was used as the sampling method, and temperature humidity index (THI) wasused to determine the comfort level.  Interview techniques with random sampling method wasused to determine the visitors perception.  The result showed that the vegetationcharacteristics of Patriot Bina Bangsa Urban Forest took effects to temperature andhumidity. High density of tree could decrease the air temperature and increase the humidity, where dense canopy class had air temperature at 27.6 ºC and humidity at 80.1%; moderatecanopy class had air temperature at 29.1 ºC and humidity at 73.2%; sparse canopy class hadair temperature at 30.1 ºC and humidity at 70.5%.  Based on the temperature humidity index(THI), Patriot Bina Bangsa Urban Forest was categorized as uncomfortable, with THI values>26.  Most of visitors (77.72%) believed that the facilities wich exist in Patriot Bina BangsaUrban Forest ware categorized good.Key words :Patriot Bina Bangsa Urban Forest, urban forest comfort, city
