Bukit Parang is a hill that is composed of intrusive diabas igneous rock which breaks through the claystone of the Karangsambung Formation at 39 mya. The process of intrusion forms a columnar joint structure that is exposed around it. The burly structure of the pole is the main attraction for visitors, in terms of geology, morphology and aesthetics. Joint column occurs in intrusive igneous rocks as well as lava flows. Magma or lava breaks down due to cooling forming cracks that are perpendicular to the cooling plane. After cracks then develop to form a polygonal plane. Parang Hill is one of 41 geological sites in the Karangsambung-Karangbolong National Geopark area, which was inaugurated at the end of 2018. The number of geo-sites is necessary so that the priority of regional development and spatial planning is better. The development of geopark and tourist villages around geosite will increase the number of visitors and the carrying capacity of the environment. This study aims to look at aspects of tourism development in terms of geosite and geomorphosite assessment which includes 5 parameters namely scientific value, educational value, economic value, conservation value and added value. The method used is field observation and quantification of the 5 (five) main parameters with weighting as a feasibility value of the Bukit Parang geosite for geotourism. These quantification values can produce information and recommendations for the management of geotourism especially in Bukit Parang, and generally in Karangsambung-Karangbolong Geopark. The values of quantification of the main parameters are 75% intrinsic and scientific value, 88% educational value, 66.67% economic value, 75% conservation value and 60% added value. The total score is 14, Mean 0.74, median 1, standard deviation 0.31 and coeffisient of variation 0.4. Based on the ANOVA test about the feasibility values ranging from 0-1, Bukit Parang has a feasibility value of 0.74.
